Abstract: A field experiment was conducted during kharif season of 2012 on loamy sand soil to study theeffect of vermicompost and biofertilizers on growth, yield and quality of cowpea. The experimentconsisted of four treatments of vermicompost (control, 2.0, 4.0 and 6.0 t ha–1) and four treatment ofbiofertilizers (control, Rhizobium, PSB and Rhizobium + PSB) thereby making sixteen treatmentcombinations tested in randomized block design with four replications. Results indicated theapplication of vermicompost 4.0 t ha–1 maximum and significantly higher the net returns over othertreatments and remained at par with 6.0 t ha–1 of vermicompost. However, seed, straw and biologicalyield, total root nodules and Leghaemoglobin content significantly increased upto 6.0 t ha–1 andremained at par with 4.0 t ha–1 of vermicompost over other treatments. But, application ofvermicompost @ 6.0 t ha–1 significantly higher in case of protein content and effective root nodulesover other treatments. The nitrogen fixation capacity unchanged under different levels ofvermicompost. Results further indicated that seed inoculation with the Rhizobium + PSB significantlyhigher seed, straw and biological yield, protein content, total root nodules, effective root nodule,leghaemoglobin content, nitrogen capacity and net returns over control and other treatments.
