Abstract: An expriment entitled “Effect of organic manures, bio-fertilizers, levels of nitrogen and phosphorus on soybean [Glycine max (L.) Merrill]” was conducted during 2014-15 at Tribal Research cum Training Centre, Anand Agricultural University, Devagadh Baria, Dist. Dahod, Gujarat. The soil of the experimental site was sandy loam in texture, free from any kind of salinity or sodicity hazards, having low in organic carbon and nitrogen, medium in available phosphorus and high in potassium. The experiment consisted of sixteen treatment combinations each of two organic manures (vermicompost @ 2.5 t ha^-1 and FYM @10 t ha^-1), levels of nitrogen (22.5 and 45 kg N ha^-1), levels of phosphorus (30 and 60 kg P₂O₅ ha^-1) and biofertilizers (No biofertilizer and Rhizobium + PSB). The experiment was laid out in randomized block design with factorial concept. The soybean variety NRC-37 was used in the experiment as a test crop. Significantly the highest seed yield (1760 kg ha^-1, 1809 kg ha^-1 and 1843 kg ha^-1) of soybean was found with the application of vermicompost @ 2.5 t ha^-1, 60 kg P₂O₅ and seed treatment of Rhizobium + PSB, respectively.
