Effect of Integrated Weed Management on Yield and Economics of Soybean

摘要

A study was conducted to know the influence of some herbicide (pre- and post-emergence) and their rates of application with and without integration of cultural practices on soybean (cv JS 80-21). Maximum weed control efficiency was recorded with clomazone applied at 1 kg a.i/ha as PE + one hand weeding at 30 DAS. Similarly maximum grain yield (1,722 kg/ha) was also obtained with this treatment. The economic analysis of different treatments revealed that maximum net return and B: C ratio was obtained with clomazone applied at 1 kg a.i./ha as PE + one hand weeding at 30 DAS which was Rs 8,260 and 1.92 respectively.
