A cowpea (Vigna unguiculata Walp L.) cultivar trail was conducted at the University of Horticultural Sciences, Bagalkot during the monsoon season in 2016. The objective of this trail is to evaluate suitable variety and optimum dose of N, P, and K for the northern dry zone of Karnataka and also to evaluate nutrition quality (protein content) of vegetable cowpea as influenced by the different nutrient management practices. Cowpea seeds are sown on different treatment beds like 125 %, 100 %, 75 %, 50 % recommend dose of fertilizers at a spacing of 45 cm row and 20 cm between the seeds. | Influence of nutrient management practices on yield quality and nutrient uptake of N P and K of vegetable cowpea Vigna unguiculata L. in northern dry zone of Karnataka India
