Influence of integrated weed management practices and biofertilizers on yield attribures and yield of Kharif soybean [Glycine max (L.) Merill] in southern Telangana agro- climatic zone

Abstract

The experiment was conducted under field conditions at Agricultural College farm, Rajendranagar. Hyderabad, Telangana State during 2014–2015 and 2015–2016, to assess the effect of Bio-fertilizers and Integrated Weed Management (IWM) Practices on yield of soybean. The experiment was laid out in split-plot design with three replications. The main treatments were Five Integrated Weed Management (IWM) practices and the sub plot treatments were four Integrated Nutrient Management (INM) practices. Days to 50% flowering were not influenced by different treatments. At harvest the number of pods plant-1 (33.32), number of seeds pod-1 (3.0, 3.1),test weight (g) (12.5,12.8), seed yield (17.21,17.35qha-1), haulm yield (25.18,25.34 qha-1) were recorded significantly highest in treatment W4 (Hand weeding at 25 and 45 DAS) in two years respectively which was on par with W1 (pendimethalin @ 1.0 kg a.i ha-1 as pre-emergence followed by hand weeding at 25 DAS) The yield of grain and haulms were not altered by the application of bio- fertilizers or their interaction with weed management treatments. Hence application of pendimethalin @ 1.0 kg a.i ha-1 as pre-emergence followed by one hand weeding at 25DAS can be recommended to realize higher yields in Southern Telangana Agro-climatic Zone.
