Experiments conducted to identify the critical period of crop-weed competition in finger millet revealed that the period from 25 to 45 days after sowing was most crucial to provide weed free condition to the crop and dely in weed removal beyond 45 days after sowing resulted in decreased grain yields. Weeding operations done earlier than 25 days after sowing affected the crop yields adversely and the weed free conditions extended beyond 45 days after lowing did not give any additional advantage. Instead repeated weedings done to provide weed free conditions for the longer duration caused adverse effect on grain yield.
