7 pages, The application of balanced fertilizers is essential to produce highquality broccoli. A field experiment was conducted to find an appropriate fertilizer management practice for broccoli (Brassica oleracea L. var. ‘Italica’) that can generate higher yield and quality. The experiment comprised 24 treatment combinations with six fertilizer management practices, i.e., T1: control. T2: cow dung at 10 t ha-1. T3: chicken manure at 10 t ha-1. T4: recommended NPK dose. T5: cow dung at 5 t ha-1 + 50% of the recommended NPK dose. T6: chicken manure at 5 t ha-1 + 50% of the recommended NPK dose. The highest plant height (60.00 cm) occurred in response to T6, the highest stem length (22.25 cm) in T4, and the maximum number of leaves per plant (22.00) in T4 and T6 treatments. Maximum fresh leaf weight per plant (609 g), stem diameter (3.98 cm), curd diameter (16.63 cm), and individual curd weight (494.50 g) occurred in response to the T5 treatment. The optimum yield (25.78 t ha-1) of broccoli can be obtained by application of cow dung (5 t ha-1) with a recommended dose of 50% inorganic fertilizer NPK (T5). Maximum TSS value (10.54%) occurred in response to T3, which was statistically similar to the effect of T6 (10.52%). Vitamin C content (80.77 mg 100 g-1) became significantly high in response to the T4 treatment (100% recommended dose of NPK). Minimum vitamin C content (53.84 mg 100 g-1) occurred in the control treatment (T1). Applying cow dung at 5 t ha-1 in addition to the 50% recommended dose of NPK fertilizers (T5) led to superior yield values in broccoli.
14 pages, via online journal, Water quality is a complex issue and residential fertilizer can be one of the many contributors to poor water quality. Working with residential audiences to help them understand and reduce their impacts on water quality is an important task among many agricultural education and Extension professionals. In order to effectively work with residential audiences, we must first understand what influences their intent to engage in fertilizer best management practices. In this research, we paired the Diffusion of Innovations and Elaboration Likelihood Model to examine the influence of perceptions of an innovation’s characteristics, personal involvement with water, and communication on intent to engage in fertilizer best management practices. The communication was presented to experimental groups as a 35-second video about fertilizer best management practices. Data were collected via a survey instrument and were analyzed using inferential procedures. Four of the five characteristics of innovations significantly influenced intent to engage in fertilizer best management practices among the control group. However, all five characteristics were significant among the entire sample but the influence was less compared to the control group. Involvement increased intent while the video treatments had little effect. The results of the research support existing findings, but also offer areas of new discovery as well as insights for practice and additional study. Future research should examine the repetition of communication as well as different dimensions of involvement.
