A field experiment was conducted during kharif season of 2013 on sandy loam soil to effect of fertility levels and biofertilizers on yield, quality and economic of cowpea. Results indicated that application of 100% RDF+ VC@ 2 t/ha significantly increases the number of pods/plant, number of seeds/pod, seed, straw and biological yield, protein, net returns and remained at par with the application of 75% RDF+ VC@ 2 t/ha over control. But seed inoculation with Rhizobium and PSB significantly higher number of pods/plant, number of seeds/pod, seed, straw and biological yield, protein and net returns over rest of treatments. However, the test weight unchanged under different levels of fertility and biofertilizers.
