Abstract:
A field experiment was conducted at Tirhut College of Agriculture, farm Dholi, Muzaffarpur, Bihar during kharif season 2016, to evaluate the effect of nutrient and weed management practices on yield, nutrient uptake and quality of soybean [Glycine max (L.) Merrill]. The experiment was laid out in split-plot design comprising of five nutrient levels in main plot and four in weed management practices in subplots with three replications. Maximum grain yield (16.94 q/ha) and total uptake of N (140.39 Kg/ha), P (9.11 Kg/ha) and K (50.53 Kg/ha) was noticed with 50% RDF along with 2.5 t FYM/ha and Vermicompost 1.25 t/ha which was significantly superior over control but statistically at par with 50% RDF + 5 t FYM/ha. In weed management practices, maximum yield (16.71 q/ha) and total uptake of N (136.92 Kg/ha), P (9.15 Kg/ha) and K (49.84 Kg/ha) was noticed with hand weeding twice at 25 and 45 DAS which was significantly superior over control but was at par with Pendimethalin 1.0 kg/ha (Pre-emergance) + one hand weeding at 40 DAS and Pendimethalin 1.0 kg/ha (Pre-emergance) + Imazethapyr 55 g/ha (Post-emergance) at 25 DAS. Protein content was not significantly affected due to different nutrient and weed management practices however maximum protein content was found with RDF (36.11%) and Pendimethalin 1.0 kg/ha (Pre-emergance) + Imazethapyr 55 g/ha (Post-emergance) at 25 DAS (36.04 %).
