The present study makes comparative evaluation of biofertilizers (brands Biopower and Biozote) and chemical fertilizers (urea and diamonium phosphate (DAP)) on yield and the quality of soybean cv. NARC-1. Significant increase in number of pods per plant, seed oil content and specific gravity of oil was observed in case of chemical fertilizer treatment. All the treatments decreased the acid value and free fatty acid (oleic acid) content of oil, maximum reduction being in the case of Biopower treatment. Biopower treated plant seed oil exhibited higher refractive index and maximum conversion to methyl esters/biodiesel.
