Influence of Bioinorganic Combinations on Yield, Quality and Economics of Mung Bean

A field study was conducted during rainy (kharif) season of 2013 to find out the effect of bioinorganic nutrient combinations on yield, quality and economics of mungbean [Vigna radiate (L.) Wilczek]. The twelve treatments comprised one control, three levels of inorganic sources (75, 50 and 100% NPK of recommended dose) and other eight in combination viz. 50% RDF+ Rhizobium + Phosphorus solublizing bacteria (PSB), 50% RDF + 2.5 t/ha Vermicompost, 50% RDF+2.5 t/ha Vermicompost/ha + Rhizobium + PSB, 75% RDF+ Rhizobium + PSB, 75% RDF + 2.5 t/ha Vermicompost, 75% RDF + 2.5 t/ha Vermicompost + Rhizobium +PSB, 100%RDF+ Rhizobium+ PSB and 100% RDF + 2.5 t/ha Vermicompost were laid out in randomized block design with three replications. Amongst combinations, significant improvement in plant height at harvest, yield attributes, yield, protein per cent, nutrient content and uptake were recorded with application of nutrients through 75% RDF + 2.5 t/ha vermicompost + Rhizobium + PSB as compared to other combinations, followed by treatments 100% RDF + 2.5 t/ha vermicompost and 100% RDF + Rhizobium + PSB. The highest and comparable net returns were obtained with the application of 100% RDF + Rhizobium + PSB (INR 52894.73) followed by 75% RDF + 2.5 t/ha vermicompost + Rhizobium + PSB (INR 51582.60) and 75% RDF + + Rhizobium + PSB (INR 50664.74). The above studies show that bioinorganic combinations have their own roles play to higher productivity, not only solely supply all the nutrients to the soils but also create favorable conditions for betters growth to producing crop.
