Abstract


Fimbristylis miliacea was most dominant weed in zero tilled condition with average contribution of 55.3 per cent at 60 days stage. Higher dry weight was observed during the second year of experiment. Anilofos 0.4 kg ha" as early post emergence application followed by 2,4-0 at 0.5 kg ha" reduced density and total dry weight of weeds at 60 days stage resulting in highest weed control efficiency (91.5 and 55.1 per cent respectively during 2001 and 2002) among herbicidal treatments. Weeds caused complete destruction of rice crop in weedy check plots. Owing to better control of weeds pendimethalin at 1.0 kg ha' followed by 2,4-0 at 0.5 kg ha
