ABSTRACT
A field experiment was conducted during the 1994 and 1995 monsoon seasons to study the effect of butachlor alone and in combination with safener. The results of the study revealed that application of butachlor 2.00 kg/ha + safener 0.188 kg/ha at 7 days after sowing (DAS) remaining statistically at par with butachlor 1.50 kg/ha + safener 0.188 kg/ha (2 & 7 DAS) and hand weeding twice, decreased dry matter accumulation and nutrient (N, P and K) uptake by weeds and increased corresponding uptake of nutrients by rice crop. Application of safener along with butachlor increased the efficacy of the herbicide at each of the times of application.
