Abstract:
The pulses are an integral part of the cropping systems of the farmers all over the country. Pulses are recognized as an indispensable constituent of the Indian diet and an important source of protein for the poor as well as for vegetarians. In participatory mode, On Farm Testing (OFT) was carried out to assess the effect of bio-fertilizers on grain yield and economics of summer green gram during the summer season of 2013-14 and 2014-15 at the farmers’ field on ten pre-selected locations in Muzaffarpur district of North Bihar. Each farmer was considered as a replication. The results of the trial explicitly revealed that the effect of bio-fertilizers was found effective to touch the level significance for grain yield production. The grain yield (999.40 kg ha^-1) data showed that treatmenti.e. RDF (N₂₀-P₄₀-K₀₀kgha^-1) along with Rhizobium + Phosphorus Solubilizing Bacteria (PSB) were statistically significant over RDF (N₂₀-P₄₀-K₀₀ kgha^-1) and Farmers’ Practice. A maximum Net Return (Rs. 34690.00 ha^-1) and B:C ratio (3.51) was found in thetreatmentN₂₀-P₄₀-K₀₀ kgha^-1 along with Rhizobium + Phosphorus Solubilizing Bacteria-PSB as compared to RDF and Farmers’ Practice.
