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. The crop growth, and yield of soybean were significantly influenced by the weed management treatments. The plants were stunted with low height throughout the growth due to overcrowding of weeds that were not removed. The plants attained maximum height of 42.6 cm at harvest in 2014. The height was 43.6 cm in 2015. Leaf area index is an important vegetative growth parameter. The pre emergence application of pendimethalin @ 1.0 kg a.i ha<sup>-1</sup> increased the leaf area index of soybean seedlings. Maximum leaf area index developed at 60 days due to hand weeding at 25 and 45 days. There was no remarkable variation due to the integrated weed management treatment. Maximum dry weight of 4423 kg ha<sup>-1</sup> was obtained in 2014 and 4533 kg ha<sup>-1</sup> in 2015 due to hand weeding at 25 and 45 days after sowing.
