Abstract
A field experiment entitled “Performance of cowpea [Vigna unguiculata (L.) Walp) under different levels of phosphorus and potassium in combination with biofertilizers” was conducted at crop research farm of Division of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, during kharif 2018. The soil of the experimental field was clay loam in texture, neutral in reaction (pH = 6.9), low in available nitrogen, low in available phosphorus, medium in available potassium and medium in organic carbon. The experiment was laid in RBD design having nine treatments and three replications. The observation revealed that grain yield (10.57 qha-1), straw yield (18.94 qha-1), yield attributes was high with the application of RDF (30N+60P2O5+30K2O) kg ha-1 + seed inoculation with PSB and KSB than other treatments. The RDF+ seed inoculation with PSB and KSB recorded 15.89% high grain yield than RDF (30N+60P2O5+30K2O) kg ha-1. B:C was also recorded more with application of RDF + seed inoculation with PSB and KSB (2.99) and was followed by RDF + seed inoculation with PSB (2.62) whereas lowest benefit cost ration was recorded with control treatment (2.24).
