Effect of integrated nutrient management on yield attributes and quality of soybean.

摘要

A field experiment on integrated nutrient management in soyabean cv. DS-228 (Phule, Kalyani) was conducted during kharif 2005 on a medium black soil in Pune, Maharashtra, India. The treatments consisted of T1: absolute control, T2: 100% recommended dose of fertilizer (RDF, 50:75 kg N:P/ha), T3: 100% RDF+farmyard manure at 5 t/ha, T4: 50% RDF+50% N (FYM)+50% P (rock phosphate) and 100% RDF (FYM)+100% P (rock phosphate). T3 recorded the highest number of pods (43.50), seeds (106.35) and pod weight per plant (25.15 g), seeds per pod (3) and 1000-seed weight (182.00). Significantly the highest seed yield of 4464.2 kg/ha was obtained with T3 and was at par with T4 (3348.20 kg/ha) and T2 (3333.32 kg/ha).
