Abstract:

A field experiment was conducted during Kharif seasons of 2018 and 2019 at Instructional Farm, Jaguli Bidhan, Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, with an objective to identify the best weed management practice in transplanted scented rice. The field experiment was laidout in a randomized block design replicated thrice with twelve treatments. It can be concluded that hand weeding at 20 and 40 days after transplanting (DAT) recorded significantly lower total weed density, total weed biomass, higher weed control efficiency and also higher grain yield, straw yield, and harvest index which were statistically at par with pre-emergence application (PE) of pretilachlor 1.5 kg/ha at 2 DAT followed by (fb) post-emergence application (PoE) of bispyribac-sodium at 25.0 g/ha at 20 DAT. Thus, it can be used as the better option for managing weeds and achieving higher productivity by the growers of the locally popular scented transplanted Gobindabhog rice variety in the new lower Gangetic  alluvial zone of West Bengal.
