12 pages, via online journal, This study aimed to investigate elementary school students’ needs and preferences regarding urban agriculture. In total, 1268 students in grades 4 to 6 at four elementary schools in Seoul, South Korea, participated in the study. A 21-item questionnaire was developed and distributed in each school by trained researchers for 3 weeks in Oct. 2017. More than 73.7% of the students reported having an awareness of and need for urban agriculture, and 86.8% (N = 1048) indicated their participation intention. Students noted needing urban agriculture for scientific inquiry and recommended including a learning activity in urban agriculture (35.4%, N = 400) for psychological stability and stress reduction (20.9%, N = 236), and for leisure and hobby purposes (16.2%, N = 183). Students reported participating in urban agriculture activities in indoor and outdoor spaces (33.8%, N = 423) for more than 30 minutes and less than 60 minutes (42.0%, N = 525) twice per week (40.2%, N = 501) with friends (72.9%, N = 818). Preferred urban agriculture indoor activities were planting plants (21.8%, N = 822), arranging flowers (20.9%, N = 788), and making craftwork using plants (18.9%, N = 714). Harvesting (20.8%, N = 790), watering (15.1%, N = 570), and planting transplants (13.1%, N = 493) were preferred outdoor activities. Other preferred activities included playing with livestock (22.4%, N = 884), cooking with the harvested crops (21.3%, N = 805), and feeding livestock (17.2%, N = 650). The female students demonstrated greater perception, experience, awareness of the necessity, and willingness to participate in urban agriculture compared with male students (P = 0.01). The lower the grade, the more students perceived the necessity of urban agriculture (P < 0.001). The results of this study can provide basic data for the practical development of urban agriculture programs for elementary school students.
8 pages, via online journal, Rose (Rosa ×hybrida) breeders historically have bred plants based on what they personally have deemed attractive and traits required by growers to produce the crop successfully. End-user preferences were not formally considered in breeding decisions. The purpose of this study was to investigate growers’ and consumers’ opinions of roses available on the market and preferences for future roses coming into the market. A web-based survey tool was developed to measure the attributes consumers were considering in purchasing and growing rose plants, their knowledge of diseases and pests, and their hopes for new plants coming to market. A link was sent to horticultural group mailing lists as well as distributed through personal e-mail lists, Facebook, and a news release from Texas A&M University. The survey was posted for 4 months. It included ≈66 questions and took 30 minutes or more to complete. More than 2000 responses were received from rose growers and nursery consumers worldwide. The respondents preferred roses that were disease resistant, with fragrant, abundant, red, and everblooming flowers. The ideal height of the preferred rose shrubs was waist to shoulder-height. Differences were found in preferences between experienced rose growers and those who were not affiliated with rose associations on variables such as the need to use chemicals to manage diseases, the importance of foliage glossiness and large vs. small blooms, the value of roses in the garden setting, the level of difficulty roses pose in growing situations, and the willingness to pay more for a rose shrub in comparison with other garden plants. Differences also were found among age groups and preferences for flower color, fragrance, foliage color, and foliage glossiness. This information could be helpful in targeting marketing of roses.
6 pages., Via online journal., Strawberry (Fragaria ×ananassa) and caneberries (Rubus sp.) are popular crops that can bring revenue to farms and may improve farm profitability. High and low tunnels can bring a number of benefits to growers, including season extension and improved berry yield and quality, as well as management challenges. Few studies in the literature report directly on grower experiences using tunnels. We report the results of interviews of 10 independent growers who use tunnels to produce strawberries and caneberries. The results echo previous studies finding improved yield and quality, and highlight benefits and challenges around pest, weed, and nutrient management. One novel finding is the role of season extension in creating marketing opportunities. Interviewed growers caution of a learning curve and the need to start on a small scale and grow gradually. Future focus for research should include improved ventilation and mechanization.
4 pages., Via online journal., Interactive web-based questions were developed for students to review
subject matter learned in an online plant propagation course. Articulate Storyline
software was used to build nearly 250 review questions with five different testing
styles to ascertain proficiency in subject areas, including the biology of propagation,
the propagation environment, seed propagation, vegetative propagation, micropropagation, and cell culture. Questions were arranged to correspond to the
supporting textbook chapters in Hartmann and Kester’s Plant propagation: Principles and practices, ninth edition. These are open access and available to instructors
and students worldwide. Users received immediate feedback for each question
answered correctly or incorrectly. The system remembers where one leaves off,
which enables starting and stopping multiple times within a chapter. Means of preand posttest responses to nine content knowledge items showed that students
perceived a significant content knowledge gain in the course. These online interactive reviews can be adapted easily to other courses in a variety of fields,
including horticulture, botany, systematics, and biology. They can also be expanded
to overlay multiple objects and trigger events based on user response. Since inception,
the website hosting these online reviews averaged 156 unique visitors per month.
Students have reported this to be a useful tool to prepare them for course exams.

7 pages., Via online journal., This study examined how different presentation formats affected knowledge gain among school grounds managers. Results indicate large-group participants (presentation to ≈50 participants at a turfgrass field day) had greater knowledge retention than small-group participants (presentation to 6–10 participants at an interactive workshop). Small-group attendees had more flexibility to discuss issues that affected them directly and may have focused on those issues instead of the targeted information. Large-group meetings were more ridged in format and attendees were less able to deviate from the main subject matter being presented. However, the value of the small-group meeting should not be discounted, especially when athletic field grounds managers and staff require information specific to their situation. When disseminating more general information, the large-group meeting format is a better means of delivery.
10 pages., Via online journal., Pollinating insects are integral to the health of all terrestrial ecosystems and agriculture worldwide. Urbanization can greatly reduce nutritional resources and habitat for pollinators. However, these losses can be mitigated through targeted landscape practices, such as planting nectar- and pollen-rich plants and managing pollinator habitat in urban areas, especially home landscapes. As homeowners attempt to conserve pollinators through horticultural practices, they often seek the advice and guidance of horticulture retail employees. The knowledge horticulture employees have about pollinators and the recommendations they provide to customers is largely unknown. A nationwide survey was developed and distributed with the objectives to 1) assess employee knowledge about pollinators and pollination biology, 2) discover what plant and management recommendations employees were giving customers pertaining to pollinator conservation, and 3) determine where to focus possible education and outreach, as well as which topics to focus educational programs on. Our findings suggest, among our respondents, that overall knowledge was adequate, with a mean score (±sd) being 8.37 (±3.23) of a possible range of 0–14 points. Uncertified and part-time employees were identified as having significantly lower scores. The subject of plant selection was found to have the largest gap in knowledge, with a mean score of 1.82 (±0.62) of a possible three points. We identified several opportunities for educational outreach, aimed at improving employee and customer knowledge on this important subject.
5 pages., Via online journal., Food security is a growing global concern. To meet the needs of an ever-growing population, food production practices will need to evolve to maximize food quantity and quality. Controlled-environment food production has increased significantly in the United States over the past 5 years, and a component of that production includes hydroponic food crops. In an effort to better prepare a workforce with knowledge of hydroponic crop production, a new course was added to an existing greenhouse curriculum. A service-learning project was integrated in the course that allowed students to experience both growing crops hydroponically and volunteering at a local food bank with a free meal program. Self-assessment showed a significant increase in student confidence in understanding food security by the end of the course. There was also a significant knowledge gained in defining terminology, factors, and the impact of food security in a community. The three guided reflections students completed during the course identified four common themes relative to the course content and service-learning project including the following: community benefits, value of volunteering, local and global effects of food insecurity, and personal growth.

9 pages., Via online journal., Negative impacts from invasive species present a global problem. Consequently, invasive species biology has emerged as an important subdiscipline of conservation biology. One of the goals of invasive species biology is to educate the public about impacts and potential control of invasive species. The purpose of this study was to determine if a lecture, a lecture and laboratory learning model, or both influence college student learning gains and whether increase in knowledge results in changes in attitudes about invasive species. A pre- and posttest instrument that measured knowledge and attitudes of invasive species was administered to several different classes of students at a university and community college. One group of students received a lecture and laboratory curriculum between the pre- and posttest (the lecture and laboratory treatment group). A second group of students received a lecture between the pre- and posttest (the lecture-only treatment group) and a third group received no instruction between tests (the control group). The lecture was in the form of an electronic presentation, whereas the laboratory curriculum included a case study, a visual aid, and a scavenger hunt to educate students about examples of invasive plant and animal species. In all classes and groups, there were at least 2 weeks between administering the pre- and posttest. Results showed that the control group scores were not different between the pre- and posttest. However, both the lecture-only and the lecture and laboratory treatment groups had scores that changed after receiving the curricula. In addition, there was an effect of curricula on student learning for the three conditions. The differences between the group that received no curricula vs. the two that did indicated that the curricula were effective teaching interventions to help students become more educated about invasive species.
12 pages., Via online journal., This present quantitative study documented the demographic base of 21st century Extension Master Gardener (EMG) volunteers in the United States. As the EMG program approaches its fifth decade and momentum builds for national leadership, collaborative programming, and innovative impact reporting, it is important to understand the characteristics of the current volunteers and their coordinators. A national study of EMG coordinators and volunteers was conducted in Fall 2016. Response was strong, representing 71.4% of state programs and 7498 volunteers. Responding state coordinators are primarily white females, have a mean age of 51.2 years, and have served in their position an average of 7.2 years. Most state coordinators (94.1%) have a graduate degree (master’s or higher). Responding local coordinators are primarily white females, have a mean age of 51.9 years, and have served in their position 7.5 years. Some local coordinators (57.4%) have a graduate degree (master’s or higher). EMG volunteers responding were primarily female, white, educated, retired, and of economic means; have a mean age of 64.8 years; and have served an average of 7.7 years. Four generations [Traditionalist (born 1925–42), Baby Boomer (born 1943–60), GenX (born 1961–81), and GenY (born 1982–2000)] were represented in survey responses. EMG volunteers were 14.5% Traditionalists, 73.2% Baby Boomers, 11.5% GenX, and 0.9% GenY. There were significant differences in the age, age at initial training, years of active service, and service hours reported in 2015 (the prior complete program cycle) among four generations of EMG volunteers. Responses from EMG volunteers and their coordinators represented all six extension programmatic regions established by the EMG National Committee. Significant differences in age, years of service, and number of volunteer service hours reported in 2015 exist among EMG volunteers across extension programmatic regions. The majority of EMG volunteers responding to the survey indicated they volunteered in an urban county (80.5%), whereas 17.2% of respondents served in a suburban county and 2.1% were connected with rural counties. There were no significant differences in the average age, years of service, and number of volunteer service hours reported in 2015 for EMG volunteers in urban, suburban, and rural programs. Historical data and the present study share similar trends within demographics, including age, income, gender, education, and race/ethnicity, yet offer important considerations for future program growth and development.

8 pages., Via online journal., Online, direct selling (ODS) has become the leading way that people acquire goods, with Amazon (Seattle, WA) being the largest online vendor in the United States. This study sought to determine if horticultural businesses were engaging in ODS with Amazon, ebay, and other websites. Researchers examined the ODS activity of 498 businesses using quantitative content analysis methods, and found that 93 horticultural industry businesses were conducting some form of ODS through their websites, but only four offered products on Amazon. Results indicate that ODS remains an untapped marketplace for the horticultural industry, particularly for small, rural businesses.

7 pages., Via online journal., Although some benefits of gardening have been documented, motivations regarding participation in gardening are often considered based on anecdote. The purpose of this study was to use qualitative analysis to explore reasons gardeners from different genders and generations participate in gardening. The questions developed for this study were intentionally exploratory and left open-ended to gather a large variety of responses. Surveys were collected from 177 individuals between the ages of 7 and 94 years old. Responses were categorized into themes identified through the literature review, the pilot study, and through exploration of the data. Responses could fit into as many categories as were mentioned by the respondents and were categorized by three independent coders. Interrater reliability was assessed using a two-way mixed, absolute agreement, average measures intraclass correlation (ICC) and determined the degree to which coders provided consistency in their ratings across participants. Themes developed through this survey included “social interaction,” “aesthetics,” “food availability/health/nutrition,” “economics,” “therapeutic,” “environmental benefits,” “nostalgia,” and “personal productivity.” Themes of personal productivity and nostalgia are those which have not occurred in previous research. Statistically significant differences were found in comparisons among males and females with more males gardening for food/health/nutrition and for reasons regarding nostalgia. More females reported gardening for personal productivity when compared with males. No significant difference was identified in comparisons of gardeners from various age groups indicating that gardeners across generations have similar intentions and receive similar benefits.

7 pages., Via online journal., The availability and cost of agricultural labor is constraining the specialty crop industry throughout the United States. Most soft fruits destined for the fresh market are fragile and are usually hand harvested to maintain optimal quality and postharvest longevity. However, because of labor shortages, machine harvest options are being explored out of necessity. A survey on machine harvest of blueberries (Vaccinium sp.) for fresh market was conducted in 2015 and 2016 in seven U.S. states and one Canadian province. Survey respondents totaled 223 blueberry producers of various production sizes and scope. A majority (61%) indicated that their berries were destined for fresh markets with 33% machine harvested for this purpose. Eighty percent said that they thought fruit quality was the limiting factor for machine-harvested blueberries destined for fresh markets. Many producers had used mechanized harvesters, but their experience varied greatly. Just less than half (47%) used mechanical harvesters for fewer than 5 years. Most respondents indicated that labor was a primary concern, as well as competing markets and weather. New technologies that reduce harvesting constraints, such as improvements to harvest machinery and packing lines, were of interest to most respondents. Forty-five percent stated they would be interested in using a modified harvest-aid platform with handheld shaking devices if it is viable (i.e., fruit quality and picking efficiency is maintained and the practice is cost effective). Overall, the survey showed that blueberry producers have great concerns with labor costs and availability and are open to exploring mechanization as a way to mitigate the need for hand-harvest labor.

9 pages., Via online journal., Water is becoming scarcer as world population increases and will be allocated among competing uses. Some of that water will go toward sustaining human life, but some will be needed to install and support landscape plants. Thus, future water resource availability may literally change the American landscape. Recent research suggests that consumers’ attitudes and behavior toward potable water supplies have changed in other countries because of greater social awareness and increasingly widespread exposure to drought conditions. We conducted an online survey of 1543 U.S. consumers to assess their perceptions about landscape plants, the water source used to produce them, and plant water needs to become established in the landscape. Using two separate conjoint designs, we assessed their perceptions of both herbaceous and woody perennials. Consumers placed greater relative importance on water source in production over water use in the landscape for both herbaceous and woody perennials included in this study. They preferred (had a higher utility score for) fresh water over recycled water and least preferred a blend of fresh with recycled water for perennials and recycled water used for woody perennial production. In addition, the group that did not perceive a drought but experienced one placed a higher value (higher utility score) on nursery plants grown with fresh water compared with those which were actually not in drought and did not perceive one. Educational and promotional efforts may improve the perception of recycled water to increase the utility of that resource. Promoting the benefits of low water use plants in the landscape may also facilitate plant sales in times of adequate and low water periods.
2 pages., Via online journal., Multistate collaborations enable extension professionals to reach their audience across a region with similar production challenges. The objective of this article is to introduce the three proceeding manuscripts delivered at the American Society of Horticultural Sciences annual conference in Atlanta, GA, as part of a workshop entitled “Advancing Technology Adoption and Achieving Extension Impact: A Working Group Success Story.” Topics discussed in the following manuscripts include the development of a multistate working group and the advantages associated with participation, development and impact of book or electronic book publications, and survey results from more traditional hands-on workshops. The goal of this workshop was to provide guidance to others who wish to establish multistate, multidisciplinary collaborative teams as well as use new education formats.

10 pages., Via online journal., Three, 2-day hands-on experiential learning workshops were presented in three southeastern United States cities in June 2014, by the Southern Nursery Integrated Pest Management (SNIPM) working group. Attendees were provided 4 hours of instruction including hands-on demonstrations in horticultural management, arthropods, plant diseases, and weeds. Participants completed initial surveys for gains in knowledge, skills, and abilities as well as their intentions to adopt various integrated pest management (IPM) practices after the workshop. After 3 years, participants were again surveyed to determine practice adoption. Respondents changed their IPM practice behavior because of attending the workshops. Those returning the survey set aside more time to scout deliberately for pests, plant diseases, and weeds; used a standardized sampling plan when scouting; and adopted more sanitation practices to prevent plant disease. Fewer horticultural management practices were adopted than respondents originally intended. Future emphasis should be placed on using monitoring techniques to estimate pest emergence, for example, traps and pheromone lures, as well as plant phenology and record keeping. However, more work is needed to highlight both the immediate and long-term economic benefits of IPM practice adoption in southeastern U.S. nursery production.
9 pages., Via online journal., Certain pesticides are coming under scrutiny because of their impact on pollinator insects. Although most consumers express willingness to aid pollinators, the reasons for consumers’ preferences or barriers to purchasing pollinator-friendly plants and the types of pollinators’ that consumers are trying to protect are less understood. Using an online survey of 1200 Connecticut (CT) consumers, of which 841 had home landscapes, we find that 46% of consumers with home landscapes purchased pollinator-friendly plants to attract pollinators to their landscape. Consistent with past research that focused on consumers’ preferences for pollinator-friendly plants, the data also reveal that some consumers are willing to pay premiums for plants that contribute to pollinator’s health. However, only 17% stated that attracting pollinators was their primary motivation; a finding that suggests labeling alone will likely not motivate consumers to purchase plants. The major barriers to purchasing pollinator-friendly plants included lack of labeling (cited by 28%), followed by high price (28%). Consumers purchasing pollinator-friendly plants were trying to attract butterflies (Lepidoptera) (78%), bees (Apidae) (59%), hummingbirds (Trochilidae) (59%), and other birds (41%). We also find that demographics and purchasing behavior affect barriers and types of pollinators desired. Simply labeling plants has the potential to increase purchasing, but increasing price could be detrimental as many consumers feel pollinator-friendly plants are highly priced. Implications for ornamental horticulture stakeholders are discussed.
8 pages., Via online journal., With growing interest in food system solutions to address poor health outcomes related to preventable chronic diseases, organizations and researchers are examining the value of community gardens as interventions to promote individual and community health. Research suggests that participation in community gardens improves access to fresh, healthy foods and increases fruit and vegetable consumption. In addition to these physical benefits, research also documents a variety of social and communal benefits, by expanding social capital, stabilizing neighborhoods, and cultivating relationships. Unfortunately, most of these studies focus on a specific case, cross case, or intervention studies within a geographically specific locale. Learning lessons from successful community garden programs can be difficult because community gardens often rely on the synergy of a complex network of support agencies that assist in various technical and educational capacities. The purpose of the study was to demonstrate the use of a framework for program development and evaluation that stakeholders, including extension, can adopt to show program outcomes. The framework used a Delphi approach with a diverse panel of community garden stakeholders to reach consensus about program outcomes. The study demonstrated that the panel could reach consensus on a variety of short-, medium-, and long-term outcomes.
9 pages., Via online journal., Little information has been published on the business and marketing practices of landscape firms, an important sector of the green industry. We sought to profile the product mix, advertising, marketing, and other business practices of United States landscape firms and compare them by business type (landscape only, landscape/retail, and landscape/retail/grower) as well as by firm size. We sent the 2014 Trade Flows and Marketing survey to a wide selection of green industry businesses across the country and for the first time included landscape businesses. Herbaceous perennials, shade trees, deciduous shrubs, and flowering bedding plants together accounted for half of all landscape sales; 3/4 of all products were sold in containers. However, landscape only firms sold a higher percentage of deciduous shrubs compared with landscape/retail/grower firms. Landscape businesses diversified their sales methods as they diversified their businesses to include production and retail functions. Landscape businesses spent, on average, 5.6% of sales on advertising, yet large landscape companies spent two to three times the percentage of sales on advertising compared with small- and medium-sized firms. Advertising as a percent of sales was three to four times higher for landscape/retail/grower compared with landscape only or landscape/retail firms; most respondents used Internet advertising as their primary method of advertising. The top three factors influencing price establishment in landscape businesses were plant grade, market demand, and uniqueness of plants, whereas inflation was ranked as the least important of the nine factors provided. A higher percentage of small and medium-sized firms perceived last year’s prices as more important in price establishment compared with large firms. A high percentage of large landscape companies said the ability to hire competent hourly employees was an important factor in business growth and management, but this was true only for about half of the small and medium-sized landscape companies.
3 pages., Via online journal., Increased global trade coupled with diversified employment opportunities demand college graduates possessing well-developed professional skills. Recent survey results identified the importance of professional skills among candidates seeking employment, with communication being recognized as the most important skill or quality when selecting candidates. The ability to work within a team structure, solve complex problems, and organize and prioritize work also ranked high among industry employment needs. Despite a rigorous focus on discipline-oriented knowledge and skills, development of professional skills in students of horticulture may be overlooked or not fully developed. Teaching methods can be modified to incorporate development of professional skills and discipline-oriented knowledge to enhance student employment preparedness and directly address industry needs.
7 pages., Via online journal., The purpose of this study was to determine college students’ understanding of invasive species and their support for plant and animal pest control and eradication methods. Surveys were administered at a university and community college in Texas in biology and agriculture departments. A total of 533 respondents participated in the study. Most students said they were not part of any type of environmental organization and felt they were not very informed about invasive species issues. More students reported learning about invasive species in high school than in college courses. The average score on knowledge questions related to invasive and native plants and animals was 32%. Most students underestimated the negative impact of invasive species but many were aware of costs to manage those species. Reliable reported sources of information included environmental organizations, college courses, and the Internet. Pearson product-moment correlations showed positive relationships between students who had college class instruction regarding invasive species and positive attitudes toward management of invasive species. Positive relationships were also found between instruction and an awareness of invasive plants or animals. Respondents who were knowledgeable of invasive species in the community had more positive attitudes toward the management of invasive species. In demographic comparisons, differences were found with males, upperclassmen, and those identifying as Caucasian or other having more knowledge of invasive species and more positive attitudes toward their management.
4 pages., Via journal article., Learning by doing plays a critical role in a learner’s conceptual understanding. By actively engaging with a concept, students gain experience and develop an enduring understanding of the concept. The concept of pollen viability is a critical component in the field of plant breeding and can be used to explain various aspects of pollen quality. An inquiry activity was designed to expose undergraduate students in a horticulture course to the concept of pollen viability and its application. The entire class was tasked with collaborating to identify an in vitro germination medium optimized to germinate plumeria (Plumeria rubra) pollen. To determine optimum sucrose and pH concentrations of the medium, student groups were assigned treatments of pollen from two plumeria cultivars that were germinated in Brewbaker and Kwack media of differing sucrose and pH concentrations. Students calculated the percentage of germinated pollen and assessed pollen tube integrity and used these variables as evidence of an optimized medium. Although undergraduates were engaged in authentic research practices during the inquiry activity, lack of time and resources impeded completion of the activity. However, students were exposed to methods and instrumentation directly related to evaluating pollen viability. Moreover, they were exposed to the basic practice of pollen quality assessment that they can use to carry out investigations on pollen fertility. In addition, insight was gained to improve the inquiry activity in the future. Now, well-informed modifications to the inquiry activity can be made to pilot this activity in a formal horticulture laboratory section.
3 pages., Via online journal., Student engagement in the classroom is critical for effective learning. To enhance student engagement, several teaching approaches can be used, including a flipped classroom approach and virtual field trips. The flipped classroom approach was used in an undergraduate tropical production systems course in which students viewed lecture materials outside of class, brought their smart devices to class to review materials, searched for new information on the Internet, and participated in small group discussions. In the virtual field trip assignment, each student visited a commercial farm or nursery, interviewed the owner or manager, and gave a presentation to the class about the operation of the enterprise and its sustainable practices.

12 pages., Via online journal., Advances in precision agriculture technologies provide opportunities to improve the efficiency of agricultural production systems, especially for high-value specialty crops such as fresh apples (Malus domestica). We distributed an online survey to apple growers in Washington, New York, and Michigan to elicit stakeholder perceptions of precision agriculture technologies. Findings from this study demonstrated that growers are willing to adopt precision agriculture technologies when they receive results from applied research projects and are engaged with active extension programs. The availability of customized services and purchasing and rental options may minimize the effects of the economies of size that create barriers to adopting increasing access to technologies. Finally, respondents deemed collaborative efforts between industry and academic institutions crucial for adapting the innovation to better address the needs of growers.
10 pages., Via online journal., A survey of Connecticut consumers was used to investigate perceptions of various green industry retailers. Consumer perceptions of independent garden centers (IGC), home improvement centers (HIC), and mass merchandisers (MM) business practices and their perceived value were assessed. Analysis of variance and ordinary least squares regression models were used to analyze the data. Results indicated that customer service, knowledgeable staff, and high-quality plants are important factors when consumers are deciding where to shop. IGCs were ranked highest in perceived customer service, knowledgeable staff, and plant quality, followed by HICs. MMs were ranked lowest for the majority of measured business practices, with the most notable exception being price. Additionally, IGCs, HICs, and MMs are perceived differently across age cohorts.
6 pages., Via online journal., Plant Madness was a classroom activity developed and implemented for the Landscape Plants II identification course at Kansas State University. The game was modeled after the National Collegiate Athletic Association college basketball March Madness tournament and Bracketology. One activity objective was to provide students an opportunity to learn new and recent cultivars and plant species not specifically covered in the class curriculum. The activity also provided students opportunities to practice public speaking skills, an avenue to be creative, and simply have fun in class. In Plant Madness, each student randomly drew a plant from a hat and then students were randomly assigned tournament seed rankings (preliminary rankings). On specified game days, one student played against another student, each having 2 minutes of play. Student play varied, and consisted of defining different plant attributes, landscape appeal, and interesting facts, for example; or identifying the opposing student’s plant’s faults through riddles, poems, games, songs, or simply recitation. Referees (e.g., guest faculty, graduate students) reviewed student play and awarded points, and the student with the highest score advanced to the next round through the single-elimination tournament. A postactivity survey was administered [Spring 2016 and 2017 (n = 44)] to obtain student feedback. When asked if the students liked the activity, it was nearly unanimous, 98% liked Plant Madness. Similarly, most students (93%) self-reported the activity increased their awareness of new or recent plant cultivars. When asked to rate the activity compared with other class approaches for learning different plants based on a scale of 1 (excellent) to 5 (poor), the average rating was 1.8. Students’ average rating for their ability to be creative for Plant Madness was 1.8 (1 = to a large extent, 5 = not at all). Ninety-five percent of the students recommended repeating the activity.
3 pages., Via online journal., Increased global trade coupled with diversified employment opportunities have generated demand for college graduates to possess enhanced interpersonal and foreign communication skills and a well-developed understanding of foreign culture. Horticultural employment opportunities also require students to possess a mastery of horticultural theory with an established record of direct, hands-on experience. Despite these needs, financial limitations of students and academic departments coupled with a lack of available opportunities may restrict students from developing these critical skills. Through development of cooperative learning programs, students have an opportunity to master and refine their horticultural skills while simultaneously raising funds, which are allocated for professional development including an international learning program. This article provides a successful overview of a student-based cooperative learning program that enhances student learning opportunities.

6 pages., Via online journal., Electric lamps are widely used to supplement sunlight (supplemental lighting) and daylength extension (photoperiodic lighting) for the production of horticultural crops in greenhouses and controlled environments. Recent advances in light-emitting diode (LED) technology now provide the horticultural industry with multiple lighting options. However, growers are unable to compare technologies and LED options because of insufficient data on lamp performance metrics. Here, we propose a standardized product label that facilitates the comparison of lamps across manufacturers. This label includes the photosynthetically active radiation (PAR) efficacy, PAR conversion efficiency, photon flux density output in key wave bands, as well as the phytochrome photostationary state (PSS), red/far red ratio, and graphs of the normalized photon flux density across the 300–900 nm wave band and a horizontal distribution of the light output.

11 pages., Via online journal., Aquaponics, an integrated system with both hydroponic plant production and aquaculture fish production, is an expanding alternative agriculture system. Many key questions about the overall feasibility of aquaponic systems remain unanswered. Of particular concern for start-up and established producers alike are consumer perceptions and willingness to pay for aquaponic produce and fish. This study reports results and analysis of a consumer survey about perceptions and preferences for aquaponic-grown products that was conducted in Minnesota during Feb. 2016. Probit and ordered probit models are used to evaluate the probability of different consumer demographic segments having various levels of knowledge and perceptions about aquaponics. About one-third of respondents had previously heard of aquaponics, and upon learning more about the system through the survey, respondents tended to be generally neutral or favorable to aquaponics. Price might be an issue for many consumers, but many tend to believe that aquaponics can impact the environment in a positive way. The results represent a first step toward building knowledge about the potential consumer base for aquaponics, which is a critical piece in the system’s potential overall profitability. It appears that consumer education and marketing will be key for the expansion of the market.

11 pages., Via journal article., The study focuses on frost protection for early-season (early-ripening) peach (Prunus persica) varieties, which are an important crop for producers in the southeastern United States. Using in-depth interviews with four major Georgia peach producers, we explore their frost protection management strategies. This information is the first step in developing a comprehensive research agenda to advise cost-effective frost protection methods for peach cultivation. We found that peach producers are concerned about frost impacts on their crops. Although early-season peach varieties are particularly susceptible to frost impacts, producers still dedicate significant acreage to these varieties, aiming to extend the market window, satisfy sales contracts, and meet obligations for hired labor. However, early-season varieties do not result in high profits, so producers prefer to concentrate on frost protection for mid- and late-season varieties. Producers employ a variety of frost protection methods, including passive methods (such as planting sensitive varieties in areas less susceptible to frost and adjusting pruning/thinning schedules) and active methods (such as frost protection irrigation and wind machines). The choice among active frost protection methods is based on factors such as the planning horizon, initial investment needs, frequency of frost events, and the effectiveness of the frost protection method. Problem areas that producers identified included improving the effectiveness of frost protection methods; reducing initial investments required to install frost protection systems; and employing better spatial targeting and configuration of frost protection strategies (to reduce investment costs while maintaining or improving the effectiveness of frost protection). Although the initial investment costs of enhanced protection systems may limit producers from actually adopting such methods, the operating costs of such systems are relatively low and have a limited effect on the decision to employ frost protection during a particular frost event. However, producers use information about critical temperatures for different bud stages, and hence, improving the quality of information regarding frost susceptibility can help producers make better frost protection decisions (and potentially reduce electricity costs and water use for frost protection).

6 pages., Via online journal., Based on a survey of the American Society for Horticultural Science (ASHS), membership need was identified for an online peer review system to validate innovation and recognize excellence in science-based teaching and extension scholarship for promotion and tenure purposes. This system would also provide a clearinghouse for instructional materials of merit for use in classrooms, laboratories, and outreach education, which fall outside the parameters of the three academic journals of ASHS. It was determined HortTechnology already provided a valued outlet for peer review of manuscript style teaching and extension scholarship; however, a need was identified for a mechanism to provide peer review of instructional materials which did not conform to a traditional manuscript format. Herein we describe the process that led to the development and launch of HortIM™, a new peer review system for teaching and extension instructional materials. An online peer review process for juried assessment of instructional materials such as articles, bulletins, case studies, fact sheets, instructional videos, teaching modules, and laboratory exercises was developed. A beta test of initial solicited materials in each category was piloted resulting in an initial database of these scholarly materials. This activity culminated in an initial opening of the system for submissions in Fall 2016. This article documents the development of HortIM™, including the submission and review process.

10 pages., Via online journal., We held a technology session at the 2016 Annual Meeting of the American Society for Horticultural Science in Atlanta, GA, to provide guidance for technology choices in extension education and an opportunity to learn more about engaging new audiences, including the millennial generation (people born between 1982 and 2000). The use of technology is now an integral part of extension-client interaction. Presenters in the session gave examples of when technologies such as blogs, social media accounts, or web conferencing tools allowed extension personnel to increase engagement with online consumers and ultimately help fulfill extension’s mission of extending knowledge and changing lives. Effective engagement requires both educators and learners to be satisfied with the exchange. It is critical to monitor the quality of these digitally facilitated exchanges as compared with traditional face-to-face interactions. Additionally, it is possible to quantify digital engagement with readily available metrics, such as “retweets” (a reposted or forwarded message) or “likes” (indication an item is appreciated). These allow innovative and substantive reporting to further justify continued use of digital technologies for enhancing client-extension relations.
6 pages., Via online journal., This study examines the impact of a residential horticultural career academy, Camp Tomorrow’s Undergraduates Realizing the Future (TURF), conducted from 2010 to 2016 at Oklahoma State University (OSU) in Stillwater, OK. Each year, up to 25 Oklahoma high school students were engaged in 2 weeks of hands-on activities representing a variety of horticulture-related careers. Instructors for Camp TURF included OSU faculty, staff, and graduate students from the Department of Horticulture and Landscape Architecture, related OSU departments, and horticulture and landscape architecture industry professionals. The Oklahoma State Regents for Higher Education sponsored this career academy, which was geared toward potential first-generation college students, and helped to expose students to the university atmosphere as well as expand their knowledge of science- and math-related career fields. Pre- and postassessments given at Camp TURF show significant changes in college readiness and familiarity with horticulture careers, but did not necessarily increase interest in particular horticulture and landscape architecture careers. Upon following up with academy graduates, we learned that the academy has been a positive experience for numerous attendees, with 76.6% going on to higher education and two students majoring in horticulture and landscape architecture-related areas.

7 pages., Via online journal., South Carolina public schools consistently rank low in academic performance. In addition, 39% of elementary, 40% of middle, and 30% of high school students within the state are classified as overweight or obese. School garden-based learning (GBL) is a low-cost and high-impact initiative that addresses both poor academic performance and childhood obesity. This study examined how school-based gardens, as part of a pilot farm-to-school (FtS) initiative, are administered and used within academic and cafeteria meal programs. An online survey was developed and sent to 102 educators who previously completed an online training course entitled School Gardening for South Carolina Educators during the 2012–15 academic school years. Data were collected from 37 educators (36% response rate). Survey results indicate that the majority of these educators, although they completed the training course, were unaware that their garden was a component of an FtS program. Moreover, gardens were not integrated with school-wide programs, especially in the cafeteria: most gardens did not contribute food to the cafeteria and meals offered most often did not align with plants learned about in the gardens. Successes of the pilot program were that the majority of educators started and maintained their garden for over 1 year and they were able to use their gardens during the day for academic instruction in multiple disciplines, including math, science, and nutrition.
7 pages., Via online journal., Virtual plant walk maps were developed for an ornamental plant identification (ID) course, with the goal of providing an additional study resource to potentially enhance student learning. The maps provided students an opportunity to revisit plants covered in lecture and laboratory sections at their own convenience, using either a computer or mobile device. Each map plotted the locations of the plants from the corresponding list and provided photographs of specimens, plant family, common and scientific names, and plant type information. At the end of the course, a survey was given to collect information about student use and perceptions of the virtual plant walk maps for two fall semesters (n = 87). Survey results indicated 63% of the students used the virtual plant walk maps as a study resource. Students who used the maps reported accessing the maps an average of 3.2 times between receiving the maps and taking the plant ID quiz in laboratory. Students mainly used the maps to study the most current plant list and accessed previous plant list maps to a lesser extent. About 67% of students who used the virtual maps, used the maps to visually review the plants online only, although 31% of students used the maps for both visual review and to physically retrace the plant walk to view the live specimens. Of the students who did not use the maps, most found other study resources/methods more useful or they forgot about the maps as a resource. When asked to rate usefulness of the maps on a scale from slightly useful (1) to very useful (3), 43% of students indicated that the virtual maps study tool was very useful, 25% indicated the maps were useful, and 8% indicated that the maps were slightly useful. A significant dependence between student use frequency and student usefulness ratings of virtual plant walk maps was observed. As students’ use of the virtual maps increased, they perceived the maps to be more useful to their studies in preparing for ID quizzes. No differences between plant ID quiz scores were associated with virtual plant walk map use, learning style, or use by learning style. Our survey indicated that students used the virtual plant walk maps as a resource and perceived the maps as a useful tool in preparation for ID quizzes.

8 pages., Via online journal., The objectives of this study were to examine the effects of a horticultural activity program on the emotional intelligence, prosocial behavior, and scientific investigation abilities and attitudes of kindergarteners. A total of 336 children aged 5 to 7 years in public and private kindergartens and day care centers in Incheon, South Korea, participated in a 24-session horticultural activity program. This program included indoor and outdoor activities such as planting seeds, transplanting plants, making and applying eco-friendly fertilizer, watering, harvesting, using plants to make crafts, and cooking with produce. It was designed to improve the emotional intelligence, prosocial behavior, and scientific investigation abilities and attitudes of kindergarteners. Each session lasted an average of 50 minutes and was held once per week. The results of the study showed that the 24-session horticultural activity program improved the emotional intelligence, prosocial behavior, and scientific investigation abilities and attitudes of the children (P < 0.05). Satisfaction with the program was very high among both the children and their teachers and parents. Future studies should consider exploring the effects of horticultural activity programs on children in different age groups.

10 pages., Via online journal., There is a growing body of literature that explores the benefits of school gardening for children, but few studies have been conducted in Taiwan. Even fewer studies have examined which factors influence the benefits that children derive from these activities. Therefore, the purpose of this study was to explore the benefits of school gardening for children in Taiwan and also identify the factors influencing these benefits. This study used qualitative research methods, which consisted of interviewing 43 elementary school students who had extensive experience with gardening, and used a general inductive approach to analyze the data. The study also used a quantitative approach to statistically compare gender differences, which found that there were some differences in preference for gardening between boys and girls in Taiwan. The results also identify seven benefits children can derive from school gardening, including increasing life skills, producing pleasant feelings, improving relationships and having plants as companions, acquiring new knowledge, experiencing the aroma and flavor of fruits and vegetables, improving health, and increasing connection to nature. Some of these benefits of school gardening have not been mentioned in previous studies and can be considered to be new, such as having plants as companions. Additionally, this study found 20 factors that influence the benefits of school gardening. Of these, eight were about plants, seven about activities, two about outdoor environments, and three about other participants. Most of the factors provide more than one benefit. The factors with the greatest impact have the most number of benefits that influence children and include “appearance, odor and texture,” “hands-on,” and “outdoor natural elements.” These factors help us to realize the unique characteristics of gardening, highlight the distinctiveness, and increase the indispensability of gardening activities.
8pgs, The retail portion of the green industry, valued at $50.55 billion, continues to provide a major connection between the industry and consumers. Given the importance of retailers in the green industry and little research exists that documents their advertising practices and impacts, the 2013 Trade Flows and Marketing Practices survey included questions to capture data for retail-only firms. This paper reports on the percentage of sales retailers allocate to promotion and advertising, including a breakdown of media used; point-of-sale (POS) materials and how they are acquired; how green industry retailers are using social media and mobile marketing [in particular, quick response (QR) codes]; the methods retailers use to collect customer demographics; customer loyalty programs (CLP); and how they are managed by retailers and a comparison of retail firms’ advertising practices by size of firm. A combination of mailed and Internet-distributed surveys resulted in a total of 699 useable retail business responses with greater than or equal to $1000 in annual revenue. The median expenditure as a percentage of sales on advertising was 3.6% for all retail firms responding with 33.7% spending no dollars on advertising. In examining the distribution based on media type, the Internet was the most frequently listed by firms (32.3%) with a mean expenditure of 42.5% of total advertising dollars. Social media was listed second most frequently (21.5%) with a mean expenditure of 29.6%. Newspapers were listed as the third most frequently used type of media (18.0%). Social media use is strong and among social media platforms, Facebook (60%) far exceeds any other platform. A third of the respondents (34.2%) reported the use of POS materials. A very small percentage of firms (3.0%) reported using QR codes and 19.4% reported having a CLP. Of those, 45.8% used customer purchase cards, whereas 35.4% used POS software. Nearly 33% of the firms collected demographic information about their customers. Of those, the method with the highest percentage use (multiple responses were permitted) was social media (50.7%) followed by CLP (48.9%), web visits (34.5%), questionnaires (15.7%), social coupons (13.5%), census data (3.9%), and marketing firms (3.1%). There were firm-size differences in seasonal employees and mean sales per employee with large firms having greater numbers than hobby, small- or medium-sized firms. There were no differences in the percentage of advertising media allocations based on firm size, but large firms used web visits, social coupons, and social media more than other types of firms to collect customer demographics. While, green industry retailers are currently using social media for marketing green industry goods, they have much more opportunity to use electronic media for CLPs and to begin using QR codes or other mobile-centric technologies to deliver in-store promotional information to consumers.
