HD-2329) seed crop. Uncontrolled weeds caused 30.7% seed yield loss as compared to season-long weed free conditions. Weed competition for the first 30 days did not reduce the yield significantly. When weeds were allowed to compete beyond 30 days i.e. upto 45 days or longer, significant reduction in yield was observed. Keeping the crop free from weeds for initial 30 days only yield was reduced significantly. Weed free period upto 45 days or more resulted in seed yield statistically alike to season-long weed free conditions. Therefore, the critical period of weed crop competition was worked out to be the first 32 to 40 DAS in wheat.Read More
