Integrated nutrient management in groundnut (Arachis hypogaea L.)

摘要

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, dry matter accumulation, number of pods/plant, pod weight/plant, kernel weight/ plant, total protein content, oil content, pod, haulm and kernel yields and 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), yield 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.
