Effect of Nutrient and Weed Management on Growth and Yield of Soybean [Glycine max (L.) Merrill] in Alluvial Soil of Bihar, India
Year: 2019
Type: article
Abstract: Field investigation was carried out to study the effect of nutrient and weed management practices on growth and yield of soybean [Glycine max (L.)] in alluvial soil of Bihar during kharif season 2016. The experiment was laid out in split-plot design having five nutrient levels in main plot and four in weed management practices in subplot. Application of 50% RDF along with 2.5 t FYM/ha and Vermicompost 1.25 t/ha recorded significantly higher plant height (54.60 cm), dry weight/plant (18.60 g), No. of leaves/plant (35.70), leaf area index at 60 DAS (5.36), No. of root nodules/plant at 30 DAS (20.46) and 60 DAS (61.31), No. of pods/plant (23.50), No. of grain/pod (2.52), grain yield (16.94 q/ha) and straw yield (28.64 q/ha) over rest of the treatments but was statistically at par with 50% RDF + 5 t FYM/ha. In weed management practices, hand weeding twice at 25 and 45 DAS recorded significantly higher plant height (55.47), dry weight/plant (18.40 g), No. of leaves/plant (35.10), leaf area index at 60 DAS (5.22), No. of root nodules/plant at 30 DAS (20.14) and 60 DAS (60.30), No. of pods/plant (22.52), No. of grain/pod (2.42), 100-grain weight (9.50 g), grain yield (16.71 q/ha) and straw yield (28.11 q/ha) over control but was at par with Pendimethalin 1.0 kg/ha (Pre-emergence) + one hand weeding at 40 DAS and Pendimethalin 1.0 kg/ha (Pre-emergence) + imazethapyr 55 g/ha (Post-emergence) at 25 DAS.
