Abstract:
A field experiment was conducted during the kharif seasons of 2018 and 2019 to study on outcomes of yield attributes, yield and economics of Rice (Oryza sativa L.) through applied the various planting methods and weed management practices. Taking all things together, there were sixteen treatment combinations comprising of four crop planting methods and four weed management practices. The experiment was laid out in Split Plot Design. Planting methods are Transplanting (20cm x 10cm), Direct seeded rice (Sprouted & line sowing) (20cm apart), Drum seeded rice (Sprouted) (20cm x 10cm) and System of rice intensification (20cm x20cm) were kept in main plot and weed management practices are Bispyribac sodium 25 gaiha-1at 25 DAS/T, Bispyribac sodium 25 gaiha-1at 25 DAS/T + hand weeding at 40 DAS/T, two hand weeding 20 & 40 DAS/T and Weedy check in sub-plots and replicated thrice. Rice planting by SRI method had maximum grain yield (32.07 and 34.36 q/ha), harvest index (46.54 and 47.43%), net return (Rs.46757/ha) and benefit: cost ratio (1.42). The two hand weeding at 20 and 40 DAS/T followed by Bispyribac sodium 25 g ai ha-1 at 25 DAS/T with hand weeding at 40 DAS/T proved to be most effective in minimizing the density of weeds and their dry weight, and in enhancing the grain yield (34.09 and 36.53 q/ha), harvest index (48.20 and 48.72%), net return (Rs 46525/ha) and benefit: cost ratio (1.35).
