摘要

Among several factors responsible for low yield of wheat, competition offered by weeds is the most important and uncontrolled weed growth may reduce wheat yield ranging from 13 to 53 percent depending upon magnitude, nature and duration of weed infestation. Wheat is predominant winter crop in north-west hills which occupies maximum acreage among rabi crops. Identification of critical period of crop-weed competition is one of the most important factors in crop production. Information on critical period of weed-crop competition in rainfed wheat under the mid-hill conditions of north-west Himalayas is lacking.
