Effect of Chemical, Cultural and Mechanical Methods of Weed Control on Wet Seeded Rice

Effective weed control in terms of reduced weed density and dry weight was achieved by pretilachlor with safener at 400 g/ha combined with sesbania (Daincha) intercropping and azolla dual cropping. The conoweeder incorporation of daincha and azolla resulted in higher weed control during early stages. Hand weeding twice and pretilachlor with safener followed by one hand weeding recorded higher weed control at later stages of the crop. Pretilachlor with safener + daincha intercropping + azolla dual cropping maintained its superiority by registering higher grain yield (5744 kg ha) which was 59.9 and 9.5% higher than the weedy check and recommended practice of two hand weedings, respectively.
