Performance of herbicides in transplanted basmati rice (Oryza sativa L.)


Author(s): Priyanka Bankoti, Shagun Gupta and Vibhuti Jhala

Abstract: A field experiment was conducted in rice during kharif season 2017 at Shri Guru Ram Rai (P.G) Collage Dehradun, (Uttarakhand). The experiment was conducted in R.B.D with three replications comprising ten treatments of weed management viz., weedy in unpuddled condition, weed free in unpuddled condition, Pretilachlor @ 750 g a.i. /ha in unpuddled condition, Oxyflorfen @ 200 g a.i./ha in unpuddled condition, Pyrazosulfuron @ 20 g a.i./ha in unpuddled condition, weedy in puddled condition, weed free in puddled condition, Pretilachlor @ 750 g a.i. /ha in puddled condition, Oxyflorfen @ 200 g a.i./ha in puddled condition, Pyrazosulfuron @ 20 g a.i./ha in puddled condition. The results showed that chemical methods of weed control significantly reduced the weed population effectively over weedy check. The tallest plants, highest dry matter accumulation were recorded with the application of Pretilachlor @ 750 g a.i./ha over rest of the herbicides in puddled and unpuddled conditions. With the application of Pretilachlor @ 750 g a.i./ha the per cent increase in grains and straw yield was 46.1 & 39 and 40.15 & 47.78 as compared to weedy check in both conditions.
