A field experiment was conducted during Kharif 2008-10 at Agricultural Research Station, Gulbarga, University of Agricultural Sciences, Raichur (Karnataka) under rainfed condition of North Eastern Dry Zone of Karnataka on a shallow black soils to study the effect of fertilizers, farm yard manure and biofertilizers on growth and yield of pigeonpea. Three years pooled data revealed significantly higher seed yield (1239 kg/ha), net return (INR 35466/ha) and BCR (2.37) following application of 100% RDF over that in 50% RDF (999 kg/ha, INR 25931 and 1.75, respectively). Addition of FYM at 5 t/ha also significantly increased seed yield (1183 kg/ha), net return (INR 31924/ha) and BCR (2.16) over that in control (1056 kg/ha, INR 29472/ha and 1.95, respectively). Combined inoculation of Rhizobium+ Phosphate solubilising bacteria (PSB) + plant growth promoting rhizobacteria (PGPR) out-performed in terms of seed yield (1192 kg/ha) and net return (INR_33613/ha) significantly over both control and Rhizobium + PSB.
