A field experiment was conducted during 2018 at the Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Jaguli, Nadia to study the effects of three irrigation regimes (CPE 60 mm, CPE 50 mm and CPE 40 mm) and five nutrition (control, FYM @ 2.5 t/ha, cowdung @ 10 t/ha, poultry manure @ 2.0 t/ha and RDF) on summer cowpea. The results showed that under plenty water supply condition, scheduling of irrigation at CPE 40 accompanied with 100% recommended dose of fertilizers (12.5:25:12.5 kg/ha of N, P and K, respectively) as basal was found to be the best treatment combination for obtaining maximum growth, yield components, pod and seed yield and moderate crop water use efficiency. Under limited or water constraint, deficit irrigation schedule at CPE 50 or CPE 60 in association with 100% RDF was the alternative option for achieving relatively higher pod and seed yield and higher to maximum crop water use efficiency. The seasonal yield response factor for cowpea was found to be 4.64.
