Abstract:
Weeds are the cause of serious concern on rice production. Therefore a field experiment was conducted during kharif season 2017 to study the effect of different herbicides on growth and yield of transplanted basmati rice at Shri Guru Ram Rai (P.G) Collage Dehradun, (Uttarakhand). The experiment were comprising ten treatments of weed management. The results indicated that chemical methods of weed control significantly reduced the total weed population (m-2) and weed dry weight (gm-2), while increased weed control efficiency effectively over weedy check. The highest number of tillers (m-2) at harvest, filled grains panicle-1, unfilled grains panicle-1, grain yield (q/ha), biological yield (q/ha) and harvest index (%) were recorded with the application of Pretilachlor @ 750 g a.i./ha over rest of the herbicides in puddled and unpuddled conditions. Besides it had highest B: C ratio under the treatment receiving Pretilachlor @ 750 g a.i./ha in puddled and unpuddled conditions. Thus, application of Pretilachlor @ 750 g a.i./ha proved better to obtained higher yield and also fetches more profit, besides suppressing weed in transplanted basmati rice.
