Abstract

The study was conducted at CCSHAU Rice Reserach Station, Kaul during kharif, 1993 and 1994 in which butachlor 1.5 and 1.0 kg/ha compared with hand weeding twice, weed-free check and non-weeded check. Lower dose of herbicide was supplemented with one hand weeding or application of 2,4-D Na 30 DAS. Highest grain yied of 53.42 q/ha was recorded with weed-free check compared to 5.36 q/ha under non-weeded check. Hand weeding twice registered grain yield of 47.68 q/ha and reduced weed dry weight (89.8 g/m2). Butachlor 1.0 kg/ha in combination with one hand weeding proved as effective as hand weeding twice in reducing weed dry weight (102.3 glm2) and increasing rice yield (45.61 q/ha). Highest net return of Rs. 12.25 thousand/ha due to weed management was obtained with butachlor 1.0 kg/ha in combination with one hand weeding which was followed by hand weeding twice (Rs.11.73 thousand) and weed-free check (11.70 thousand).
