New Research Article Received :- Integrated nutrient management in groundnut (Arachis hypogaea) A. P. Chavan , N. K. Jain , V. V. Sagvekar and Taresh Kumar Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur – 313 001 India ABSTRACT A field experiment was conducted during two rabi seasons of 2010-11 and 2011-12 to study the integrated nutrient management in groundnut (Arachis hypogaea) at Agricultural Technical School (Dr. B. S. Konkan Krishi Vidyapeeth Dapoli, Maharashtra) farm, campus-Deodhe (Lanja), district Ratnagiri, Maharashtra, India. Successive increase in fertility levels up to 125% RDF significantly increased plant height, number of branches plant-1, dry matter accumulation, number of pods plant-1, pod weight plant-1, kernel weight plant-1, total protein content, oil content, pod, haulm and kernel yields, available N and K status. The crop fertilized up to 100% RDF significantly increased shelling out-turn as well as available P status and was at par with 125% RDF. Inoculation of groundnut with Rhizobium and PSB significantly enhanced dry matter accumulation, total protein content, all yield attributes (number of pods, pod weight and kernel weight plant-1), yields and available N and P status over control (no biofertilizers). Treatment 125% RDF as well as biofertilizers significantly increased the net returns and benefit cost ratio over rest of the lower treatments. Key words: Biofertilizers, Economics, Fertility levels, Groundnut, Soil fertility status, Yield
