Abstract

Propanil spray once (3.5 kg ai./ha) or twice (7.0 kg ai /ha) were compared with hand weeding and no weeding for their herbicidal efficiency with 18-20 rica raised under different seeding methods and rates. Double sprays of propanil reduced, the weeds by 76 per cent and was close to two hand weedings. The weeding methods had significant influence on the number of productive tillers per unit area and the filled grains per panicle, Both for grain and straw yield two sprays of propanit ware as effective as two hand weedings. Transplanting contributed to greater tillering and higher grain yield while dibbling was on par with transplanting when adequate check of weeds was provided.
