Field experiment on the competitive effect of weeds for soil nutrients in hybrid maize Var. Ganga-5) indicated that weeds removed about 59 kg N, 10 kg P and 59 kg K per ha at the early stage (30 days) of the crop growth. The weeds removed 7 to 10 times more nut- rients than the crop at this stage. Pre-emergence application of simazine at 1.0 kg a. i/ha effectively checked the nutrient depletion and caused 41, 73 and 35 per cent increase in the NPK uptake of the crop over unweeded control. Simazine-treated crop recorded higher arain yield than the manual weeding treatment,
