On an average weeds reduced cane yields by 67.2%. There was no reduction in the cane yields where weeds infested the crop for the first 30 days only. Weed infestation after 30 days of planting caused significant reduction in the cane yields. Weed-free condition maintained beyond 120 days after planting did not increase cane yields significantly. It indicates that the critical period of weed control lies between 30 and 120 days after planting in spring planted sugarcane.
