Abstract:
Through the Farmers’ Participatory research, an experiment was conducted at five sites to determine the effect of resource conservation tillage (Zero-Tillage) technology on weeds in wheat crop under the rice-wheat cropping system. During first year, weed density of 22.6 weeds M-2 was observed in zero-till wheat crop, which decreased to 15.6 weeds m-` in the third year, conversely 32.4 weeds m-2 were counted in the conventional till wheat crop, which declined to 24 weeds m-2 in the last year of studies. On average, a decrease of 32% weed density in wheat crop was observed due to zero-tillage compared to the decrease of 26% weed density under conventional tillage over a period of three years. Moreover 52% lesser weeds were found in the zero-tillage fields than the crop established with conventional method. The findings suggest that zero-tillage technology for wheat crop depressed the germination and growth of weeds despite its other known benefits like facilitating earlier planting, saving of water, labour and land preparation cost.
