Abstract


A field experiment was conducted during 2009-10 at the research field of AICRP on Dryland Agriculture,                                       Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to study the effect of integrated nutrient management on soil fertility, nutrient balance, yield and economics of soybean grown in an Inceptisol under rainfed condition. The soil of the experimental site was moderately alkaline in reaction, low in available nitrogen, medium in available phosphorus and high in available potassium. Nine treatments with three replications tried in randomized block design consisted of control, 100% RDF     (30:75:00 kg ha-1), 100% RDF along with biofertilizers, 100% N through FYM along with biofertilizers, 100% RDF along with 25 kg K2O ha-1, 100% RDF along with 25 kg K2O ha-1 and biofertilizers, 50% N through glyricidia along with 50% N through inorganics, 50% N through glyricidia along with 50% N through inorganics and biofertilizers,50% N through glyricidia along with 50% N through inorganics, biofertilizers and 25 kg K2O ha-1. The results indicated that the application of 100% RDF along with 25 kg K2O ha-1 and biofertilizers resulted in higher productivity and economic returns with improvement in soil fertility and nutrient balance in soybean grown in an Inceptisol under rainfed condition.
