Field experiment was conducted at the Experimental Farm, Department of Agronomy, Annamalai University during Late samba season (September, 2017-January, 2018) with rice variety ADT 49 to study the impact of various organic manures on rice weed control. The experiment was taken up in Randomized block design with that treatments comprised of unweeded control (T1), off season ploughing treatment (T2), application of organic manures viz., goat manure @ 5 t ha-1 (T3), poultry manure @5 t ha-1 (T4), farm yard manure @ 12.5 t ha-1 (T5) and green leaf manure (Glyricidia sepium) @ 6.25t ha-1 (T6) and hand weeding twice (T7). Among the rice weed control measures, twice hand weeding at 20 and 40 DAT recorded the least weed counts, weed biomass (78.90 kg ha-1) and highest weed control index (89.84 percent) favouring higher yield attributes and grain yield (4.94 t ha-1).
