Effect of weed control practices for growth parameters in direct seeded rice (Oryza sativa L.)

Abstract

Direct seeded rice is considered one of the most effective, sustainable, and economically feasible rice cultivation methods currently in use. The present investigation was undertaken to evaluate the “Effect of weed management practices on production and productivity in direct seeded Rice (Oryza sativa L.)” at the Experimental Farm, School of Agriculture Science, LNCT University, Bhopal, (M.P.) during two consecutive years of 2023 and 2024 during kharif season. The research employed a Randomized Block Design for the experiment, which included three replications and twelve treatments (T1 - T12) of weed control. During both years of same season, the highest value of plant height (cm), number of tillers/m2, dry matter production (g/m2), leaf area index (LAI), root length (cm), root volume (g/cc) and root dry weight (g/plant) at harvest were recorded with T9 {Pretilacholr 750 g/ha (2 DAS) fb Bispyribac sodium 20 g /ha (20 DAS)}, respectively.
