Résumé
An investigation on “Nutritional requirement of vegetable cowpea in northren dry zone of karnataka” (Vigna unguiculata L.) was undertaken during kharif season of 2016. The experiment involving two varieties and five different combinations of chemical fertilizers was laid out in randomized complete block design with factorial concept and replicated thrice in Haveli farm under University of Horticultural Sciences, Bagalkot. To assess the performance of cowpea varieties for vegetative, yield and quality parameters. Analysis of variance revealed highly significant difference between varieties and treatment combinations. The variety Arka Suman (V1) found better for growth parameters (plant height, number of leaves, leaf area index and dry matter production) as well as yield parameters (number of pods per cluster, pod yield per plant, pod yield per plot, total bio mass and seed yield) and for quality traits like protein content and stover yield were found superior in Arka Suman (V1) as compare to Arka Gariam (V2). Among different chemical fertilizer treatments, the treatment F1 (125 % RDF of NPK) recorded significantly higher growth, yield and quality parameters. Gross returns, net returns and B : C ratios were found significantly higher due to adoption of 125 % RDF of NPK along with variety Arka Suman (V1) proved to be most productive as well more economical which results in higher gross return (43560.6 Rs.), net return (272141.1 Rs.) and B : C ratio (2.66:1).
