Abstract

Results of the field study indicated that post-ernergence control of weeds with non-selective herbicide glyphosate 2.05 kg ha −1 fb HW enhanced the seed cotton yield to 1412 kg ha −1, which was 200 kg more than that yield obtained with manual weeding twice (1215 kg ha −1). Pre-emergence control of weeds with pendimethalin 1.0 kg ha −1 fb a manual weeding recorded 1154 kg of seed cotton ha −1 which was also signifkantly inferior to post-emergence weed control. Lower dose of glyphosate 1.025 kg ha −1 fb HW and glufosinate 0.45 kg ha −1 also controlled the weeds effectively and produced comparable cotton yield with that of glyphosate 2.05 kg ha −1 fb HW.
