A field experiment was carried out during kharif 2001 and 2002 at field unit of All India Co-ordinated Research Project on Weed control, University of Agricultural sciences, Hebbal, Bangalore, under irrigated conditions. The treatment consisted of four weed management practices and two fertility levels. The hand weeding twice resulted in higher grain (3450 kg ha-1), followed by butachlor and 2, 4-D Na salt 0.75 kg ha-1. The higher yield was reflected in terms of yield parameters such as ear length, 1000 grain weight, number of fingers per ear head, ear weight per plant and grain weight per plant. Unweeded control treatment caused significant reduction in these traits and consequently lowered the yield by 43 per cent owing to weed competition. Application of butachlor and 2, 4 - D Na salt 0.75 kg ha-I was resulted in higher net returns and benefit cost ratio as compared to hand weeding twice and unweeded control, owing to less cost. Integrated use of recommended NPK and FYM treatment recorded significantly higher grain (3086 kg ha-1) as compared to recommended NPK alone (2946 kg ha-1). This higher yield in integrated use of recommended NPK + FYM applied plot was reflected in terms of better yield parameter like ear length, ear weight per plant, 1000 grain weight, number of fingers / ear head and grain weight per plant and growth parameter like leaf area, total dry matter production and better distribution of dry matter to graim.
