Effect of New Molecules of Herbicides on Productivity of Transplanted Rice (Oryza sativa L.)
Year: 2025
Type: article
Abstract: Weeds are a significant limiting factor in transplanted rice as they compete for the same nutrients which crop needs. Herbicide usage gaining popularity among the farmer groups especially which are sustainable in nature. The study took place at the Instructional Cum Research Farm, Barrister Thakur Chhedilal College of Agriculture and Research Station in Bilaspur (Chhattisgarh) during the kharif season of 2023. There were three replications of the experiment, and it was set up in a Randomized Block Design. The treatments included seven ways to control weeds: Florpyrauxifen benzyl + Cyhalofop butyl @ 120 (20+100 g/L) (new source technical) applied at 30 DAT (T1), Florpyrauxifen benzyl + Cyhalofop butyl @ 150 (25+125 g/L) (new source technical) applied at 30 DAT (T2), Florpyrauxifen benzyl + Cyhalofop butyl @ 180 (30+150 g/L) (new source technical) applied at 30 DAT (T3), Bispyribac-Na 10% SC @ 25 g/ha applied at 30 DAT (T4), Florpyrauxifen benzyl + Cyhalofop butyl @ 150 (25+125 g/L) (Novlect, Existing source technical) applied at 30 DAT (T5), Weed free through Hand weeding (T6), and Untreated check (water spray) (T7). In August, the test crop Indira Barani Dhan-1 was planted, and in November 2023, it was harvested. The experiment showed that T6 had the best growth traits, such as panicle length, number of grains per panicle, test weight, grain yield, and straw production. T3, T5, T4, T2, and T1 came next. Under T7, the above characteristics had the lowest levels. A study of the economy showed that treatment T3 had the highest net return, followed by T6 and T5. The B:C ratio was highest under T3 (2.30) and therapy T5 (2.16).
