ECONOMICS OF CHEMICAL WEED MANAGEMENT IN DRUM SEEDED RICE (ORYZA SATIVA L.)R. Suganya, S.M. Suresh Kumar and G. BaradhanAbstract Field experiment was conducted at Periyanarkunam during Kuruvai 2021 to evaluate the economics of chemical weed management in drum seeded rice. The experiment was conducted in randomized block design with four replications. Among the treatments, application of bensulfuron methyl 0.6% + pretilachlor 6% @ 10 kg ha-1 PE on 8 DAS fb metsulfuron methyl 10% + chlorimuron ethyl 10% WP @ 20 g ha-1 PoE on 25 DAS fb hand weeding on 45 DAS recorded the highest gross, net returns and benefit cost ratio with the lowest total cost of cultivation. Hence this method of weed management can be recommended to achieve the highest profit in drum seeded rice. |
