A field experiment on “Response of summer cowpea (Vigna unguiculata L.) to inorganic fertilizers and foliar application of bio-enhancers” was carried out during summer 2022 on loamy sand soil of Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The experiment was laid out in RBD with factorial concept with three replications. The result revealed that significantly higher plant height, Number of pods per plant, number of root nodules per plant, fresh and dry weight of root nodules, seed yield, stover yield and protein content, were recorded with 100% RDF. It also gave the higher net return and B:C ratio. Significantly higher number of pods per plant, root nodules/plant, fresh and dry weight of root nodules, seed yield and stover yield with an application of panchagavya as foliar spray @ 3% at 30 and 45 DAS. The same bio-enhancer application recorded maximum net return as well as B:C ratio.
