Abstract
The field experiment was conducted on Agronomy research farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj Ayodhya (Uttar Pradesh, India) during Kharif season 2021 and 2022. The experiment was laid out in split-plot-design with three replications. Four establishment methods viz., Direct seeded rice, Drum seeder technique, Transplanted rice and System of rice intensification (SRI) were taken in main plot, and six weed management practices viz., Penoxsulam 22.5 g ha-1 at 2-3 leaf stage of weeds DAS/DAT, Penoxsulam 22.5 g ha-1 at 2-3 leaf stage of weeds fb one hand weeding at 35 DAS/DAT, Bispyribac sodium (10%) 25 g a.i. ha-1 at 15 DAS/DAT, Bispyribac sodium (10%) 25 g a.i. ha-1 at 15 DAS/DAT fb one hand weeding at 35 DAS/DAT, Weed free (Two hand weeding) and Weedy check in sub plot. Result revealed that significantly higher crop growth rate, relative growth rate, absolute growth rate, net assimilation rate and grain yield was recorded in system of rice intensification (SRI) during both the years of investigation. Among the weed management practices, higher value recorded with spray of Bispyribac sodium (10%) 25 g a.i. ha-1 at 15 days after sowing/days after transplanting fb one hand weeding at 35 DAS/DAT.
