Abstract

Experiments were carried out to determine N uptake by weeds in crops of wheat, peas, potato, rice, maize, soybean and sorghum; weeds assimilated substantial amounts of N within 5-6 weeks of sowing crops and the nutrient drain by weeds was higher in kharif than in rabi. Herbicides, by killing weeds, effected a considerable increase in N uptake by crop plants and in yield
