Abstract :

The research was conducted with transgenic cotton hyid during winter irrigated season of 2009–10 and 2010–11 at the experimental site of Tamil Nadu Agricultural University, Coimbatore, with seven weed management methods viz., pendimethalin at 1.0 kg ha–1 + hand weeding, pendimethalin at 1.0 kg ha–1 + power weeder weeding, hand weeding on 25 and 45 DAS, power weeder weeding on 25 and 45 DAS, hand weeding on 25 + power weeder weeding 45 DAS,power weeder weeding on 25 + hand weeding 45 DAS and unweeded check. In both the years, higher seed cotton yield was recorded in hand weeding twice at 25 and 45 DAS and pendimethalin at 1.0 kg ha–1 + hand weeding also efficiently suppressed the weeds and recorded higher seed cotton yield in transgenic cotton.
