Effect of Different Pigeonpea-based Intercropping Systems and Weed Management Practices on Growth of Weeds and Yield of Pigeonpea

Field experiments were conducted during kharif seasons of 1994 and 1995 at Indian Agricultural Research Institute, New Delhi to study the efficacy to different pigeonpea-based intercropping systems in managing weeds. The results revealed that pigeonpea+cowpea intercropping system was most effective in suppressing weeds and increasing pigeonpea yield. Pigeonpea+groundnut was the next best followed by pigeonpea+moong and pigeonpea+soybean. However, pigeonpea+groundnut was the most productive system.
