Grain yield, Raised-bed, Soybean, Weed management, Zero tillage

In this study the population and dry matter of weeds was significantly more under under ZT than CT. Seed yield of soybean was the highest under CT–raised-bed, followed by ZT-raised-bed, CT–flat-bed and ZT-flat-bed. Application of pendimethalin + HW and pendimethalin + chlorimuron-ethyl resulted in almost similar weed control efficiency and gave equal seed yield. Uptake of N, P and K by grain was maximum under pendimethalin + HW, which was significantly more than rest of treatments. It was concluded that soybean can be grown under permanent raised-bed with pre- and post-emergence herbicides for realizing higher productivity.
