Influence of intercropping systems and weed management practices on the growth and yield of irrigated cotton

摘要

Field experiments were conducted at Agricultural College and Research Institute, Killikulam to find out the suitable intercrop and weed management practices on cotton under irrigated condition. The results revealed that higher growth and yield attributes and yield were recorded in sole cotton than cotton intercropped with either cowpea or soybean. Pre-emergence application of metolachlor at 1.00 kg ha~(-1) through herbigation with one hand weeding on 40 DAS significantly enhanced the growth, yield attributes and yield of cotton. The interaction between intercropping and weed management practices indicated that cotton and soybean intercropping system applied with the metolachlor herbicide as pre-emergence at 1.00 kg ha~(-1) through herbigation withone weeding on 40 DAS registered higher growth, yield attributes and yield.
