Abstract
A field trial was conducted during wet seasons of 2014 and 2015 at two locations of the district Angul, Odisha to study the crop growth, weed control, yield, economics and nutrient uptake in wetland transplanted rice as influenced by different weed management practice. Four weed management practices, viz. two hand weedings at 20 and 40 DAT, bensulfuron methyl at 60 g ha-1 + pretilachlor at 600 g ha-1, bispyribac-Na at 25g ha-1 and weedy check were laid out in randomized block design with ten replications. Panicum repense, Digitaria sanguinalis under grasses, Xanthium strumarium, Ageratum conyzoides among broad leaf and Cyperus difformis among sedges were predominant weeds in wetland transplanted rice. The results revealed that two hand weedings at 20 and 40 DAT recorded significantly higher plant height, filled grains panicle-1, grain yield, straw yield, weed control efficiency, nutrient uptake by plant which remained at par with bensulfuron methyl 60g ha-1 + pretilachlor 600 g ha-1. In terms of economics, net return and B:C ratio were higher with application of bensulfuron methyl 60 g ha-1 + pretilachlor 600 g ha-1. Pre-emergence application of bensulfuron methyl 60g ha-1 + pretilachlor 600 g ha-1 at 3 DAT considerably reduced the weed infestation registering higher weed control efficiency, higher grain yield in t wetland transplanted rice. Thus, it appeared to be effective, economically viable for weed control, crop growth, nutrient uptake, higher grain yield and profitability.
