Abstract:
A field experiment entitled “Influence of Foliar Application of Water Soluble Fertilizers on Soil Nutrient Dynamics, Yield and Quality of Summer Cowpea (Vigna unguiculata L.) was carried out during the season 2021, at SSAC Departmental Research Farm, College of Agriculture, Latur. The experiment was laid out in randomized block design with 3 replications with 9 treatments among that one is of absolute control, one of recommended dose of nitrogen and phosphorous, 3 treatments are of foliar application of individual water soluble fertilizers viz., Among the various treatments combination of foliar application of water soluble fertilizers with RNP (T9 RNP + foliar spray of 19:19:19 @ 0.5% at 30 DAS + 0:52:34 @ % + KNO₃ 1.0% @ 60 DAS) showed significant increase in content and uptake of nutrients (N, P and K) yield and the quality parameter like protein content and test weight of cowpea than foliar application of individual water soluble fertilizers (T3 RNP + foliar spray of 19:19:19 @ 0.5% at 30 DAS) over control. So it can be concluded that the foliar application of combined of water soluble fertilizers along with RNP showed significantly superior effect on soil nutrient dynamics, yield and quality as compare to the foliar application of individual water soluble fertilizer with RNP over control of cowpea on low nitrogen content soil.
