The suitable crop establishment options with appropriate amount of residue retention may lower weed infestation, better crop growth, productivity, profitability and soil health. The overall goal of the present experiment was to assess the impacts of different crop establishment options on rice growth and yield in eastern Uttar Pradesh, India. Specific objective of the study was to determine the effects of different crop establishment methods on productivity and profitability of rice.The strategy was to assess yield response measured during two consecutive seasons of the rice with different crop establishment methods. The impacts on rice yield, yield attributes and economics were assessed for different crop establishment [RE1:- Puddled transplanted rice (PTR), RE2:-Reduced till-direct seeded rice (RT-DSR), RE3:-Zero till-direct seeded rice (ZT-DSR) and RE4:-Zero till-direct seeded rice with 30cm anchored wheat residue (ZT-DSR+AR)]. The field experiment was laid out according to a complete randomized block design with four replications. The different crop establishment methods did not influence significantly the yield and yield attributes [panicles m-2 (no), panicle length (cm), panicle weight (g), grains Panicle-1 (no), 1000 grains weight (g)]of rice except number of panicle m-2 in both the years but higher value of yield and yield attributes were recorded by ZT-DSR+AR followed by ZT-DSR and RT-DSR. The highest gross return (₹ha-1), net return (₹ha-1) and B: C ratio recorded in ZT-DSR+AR that followed by ZT-DSR and RT-DSR crop establishment methods, whereas lowest with PTR.
