Abstract:
A field experiment was conducted at Instructional Farm, DKS College of Agriculture and Research Station, Bhatapara (C.G.) during Kharif season of 2021. The experiment was laid out in split plot design with 3 replications. Crop establishment methods and weed management practices were recorded to have significant influence on yield attributes and yield of rice. SRI method was significantly superior over conventional transplanting. Weed free check recorded significantly higher number of tillers plant^-1, number of panicle hill^-1, panicle length, Number of grains panicle^-1, panicle weight and test weight. Weed free check recorded significantly higher grain yield (6400 kg ha^-1), straw yield (8826 kg ha^-1) and biological yield (15227 kg ha-1) over rest of the treatments. Two hand weeding at 20 and 40 DAT followed by weed control using conoweeder at 10, 20 and 30 DAT were the next best treatment after weed free check. Among the herbicidal weed management practices, post emergence application of bispyribac-sodium 10% SC @ 20 g a.i. ha^-1 showed supremacy for yield parameters over weedy check. A combination of SRI + weed free-check (C₂W₂) recorded maximum net returns (₹79595) and benefit: cost ratio (1.37).
