5 pages, We developed an Excel-based computational template Extension educators can use to assist clientele with scheduling irrigation for efficient use of water. With the template, the user applies the dual crop coefficient method to calculate evaporation and transpiration rates separately, with the result being more accurate soil water tracking as compared to what occurs when a single crop coefficient is used. Crop water needs can be conveniently calculated on the basis of soil characteristics, crop growth stages, and weather information. Application examples demonstrate that the amount and frequency of irrigation should be adjusted according to soil texture. The template and application examples are available to Extension professionals as electronic supplementary material.

Paper presented at the 8th Associazione Italiana di Economia Agraria e Applicata (AIEAA) conference, Pistoia, Italy, June 13-14, 2019., Analysis of principal determinants of Italian farmers' adoption of sustainable irrigation technologies, considering social, economic, productive, geographical, and climatic aspects.
12 pages, We use the 2013 cotton precision farming survey data to study the adoption of irrigation technologies by cotton farmers in 14 states of the United States. We find that farmers with a higher irrigated yield, and who are from the Southern Plains (Texas and Oklahoma), adopt water-efficient irrigation technologies, such as sub-surface drip and trickle irrigation technologies. There are 10 irrigation technologies that farmers can adopt for cotton production in these 14 cotton-growing states. The intensity of the irrigation technologies, as measured by the number of irrigation technologies adopted in cotton production, is affected by the irrigated cotton yield realized, land holding (total land owned), education, computer use, and the origin of the cotton farmer being from the Southern Plains. We use a multivariate fractional regression model to identify land allocation by the different irrigation technologies used. Our results indicate that significant variables affecting land allocation with different irrigation technologies are the age of the operator, the cover crop, the information sources used, the per acre irrigated yield, the education, and the cotton farmer being from the Southern Plains.

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.
10 pages., Via online journal., The purpose of this study was to investigate the factors influencing people's participation in the exploitation of water resources for agriculture. The population consists of experts with a B.A. and higher degree employed in various sectors of Agriculture Organization, Water Organization and Research Center of Urmia city. The sample was randomly selected, and the sample size was determined through Kerjice and Morgan table to be 196. This is an applied field study. The survey tool is a structured questionnaire with close-ended question and its validity and reliability is confirmed by experienced professors, and Cronbach's alpha coefficient which indicates the validity of the questionnaire is calculated to be 0.834. The results show that there is a significant relationship among the administrative, social, cultural, educational, economic, ecological, technical, structural and political factors and the importance of people's participation in the exploitation of water resources for agriculture. The results of multiple regression showed that the independent variables explained 66 percent of the dependent variable variance. According to finding in this research these recommendation comments: Improvement and shortening of water transfer networks in order to speed up the transfer of water and reduction of water loss. Government financial support in the agricultural-industrial sector in order to use new technologies. Preventing economic, social, environmental and political losses due to Urmia Lake drying. Maintaining the diversity of plants and crops through water management and environmental management and environmental ethics. The role of mass media such as radio and television, the use of other channels of communication in highlighting the importance of optimal water consumption. Government support for farmers to renew or launch pipeline for farms and gardens to prevent water losses, as well as supporting new irrigation methods and repairing old transmission lines. Increasing cooperation between people and society and even the state regarding participation in the optimal use of water resources.
