Influence of integrated nutrient management on growth and yield of cowpea (Vigna unguiculata L.) in Prayagraj region

Abstract

A field study was conducted at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, during the zaid season of 2021. (U.P.). This study was carried out with the objective to study the interaction effect of different levels of NPK, FYM, Vermicompost and Panchagavya on growth and yield of cowpea.The experiment used a randomized block design (RBD) with nine treatments which were replicated three times. The soil texture of the experimental plot was sandy loam, with a pH of 7.2, low organic carbon (0.48 percent), available N (171.48 kg/ha), available P (13.6 kg/ha), and available K (215.4 kg/ha). The results showed significantly increase in growth parameters i.e. plant height (69.48 cm), number of nodules/plant (24.37), plant dry weight (22.22 g/plant), crop growth rate (3.0 g/m2/plant) and yield attributing parameters i.e. number of pods/plant (15.45), length of pods (27.02cm), number of seeds/pod (13.57), test weight (85.6 g), seed yield (2.68 t/ha), stover yield (6.09 t/ha). The harvest index (30.56) was recorded with vermicompost 1.5t/ha + RDF 100% kg/ha.
