ABSTRACT

Field experiment was conducted on transplanted rice cv. PR 106 during kharif season of 1999. The results revealed that combinations of crop stand and pre emergence application of butachlor led to pronounced reductions in weeds dry weight and increased grain yields. The two doses of butachlor used were equally effective under all crop stands. Statistically better grain yield obtained from the treatment combination of 44 hills m–2 with butachlor @ 1.125 kg ha–1 in comparison to those under 25 hills m–2 (both random and line plantings) with butachlor @ 1.5 kg ha–1 indicated the possibility of lowering the recommended dose of butachlor from 1.500 to 1.125 kg ha–1 under thicker crop stand.
