Field experiments were conducted to study the efficacy of different weed management practices in sugarcane during 1997-99. Cyperus rotundus, Cynodon dactylon and Sorghum halepense were the dominating weeds associated with the crop and constituted 42, 21 and 17.5% of total weed population, respectively. One hoeing at 30 days after planting followed by application of atrazine at 2.0 kg ha'! (just after hoeing) provided 70.5% weed control efficiency. This also resulted in highest cane yield being 49.5% higher than weedy and 2.4% than three hoeings done at 30, 60 and 90 days after planting. The weed infestation did not affect juice sucrose content. Commercial cane sugar yield was highest (10.0 t ha'!) with three hoeings during 1997-98 and with one hoeing fb atrazine (11.0 t ha'!) during 1998-99, though the differences were non-significant.
