A field experiment was conducted during kharif 2014-15 at College farm, College of Agriculture, Latur, VNMKV, Parbhani (Maharashtra) to evaluate the effect of 10 treatments i.e., various sources of nutrient on yield and quality of cowpea (Vigna unguiculata L.) with variety ‘Konkan Sadhabahar’. The experiment was conducted in a randomized block design (RBD) and replicated thrice. As regards the seed yield (1066 kg ha-1) and straw yield (2707 kg ha-1) were considerably higher with the application of 75 per cent RDF +Bio-fertilizers + vermicompost @ 1.25 t ha-1. The application of RDF (25:50:00 NPK kg ha-1) (T1) recorded the higher protein content (23.26) and application of 75 per cent RDF + Bio-fertilizers + vermicompost @ 1.25 t ha-1 (T6) gave highest protein yield (246 kg ha-1) due to increased yield. The obtained results might be due to the improvement of physical, chemical and biological properties of soil, improvement in the water holding capacity of soil and induced solubilisation of phosphate and helped in nitrogen fixation. This collectively resulted in increased yield of cowpea under rainfed conditions.
