Studies on efficiency of different botanical herbicides on weed management of rice (cv. Gobindobhog)

Abstract:
The aromatic rice variety Gobindobhog was used in the experiment which was carried out in RBD design with 8 treatments and 3 replications. The treatments were: T1 = Control plot, T2 =Two hand weeding @ 20 and 40 DAT; T3 =Mechanical weeding @ 20 and 40 DAT; T4 =Cyperus rotundus extract + 1 mechanical weeding at 30 DAT; T5=Echinochloa colona extract +1 mechanical weeding at 30 DAT ; T6 =Bambusa vulgaris leaf & shoot extract + 1 mechanical weeding at 30 DAT; T7=Cucumis sativus leaf extract + 1 mechanical weeding at 30 DAT, and T8=Xanthium strumanium leaf extract + 1 mechanical weeding at 30 DAT. The result revealed that the application of botanical herbicides had a significant influence on weed control efficiency, weed control index, growth and yield of crop which was found highest under the treatment T7 followed by T6. T7 treatment had maximum number of effective tiller that produced highest yield (3717 kg/ha). Thus, it may be concluded that application of Cucumber leaf extract along with one mechanical weeding at 30 DAT gives highest weed control efficiency.
