Studies on efficacy of pre-mix penoxsulam + pendimethalin on weed growth of direct seeded rice

Abstract

The present investigation entitled “Sudies on efficacy of pre- mix penoxsulam + pendimethalin on weed growth, yield and economics of direct seeded rice” was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur during kharif season of 2015. The soil of experimental field was sandy loam in texture (Inceptisols), neutral in pH and has 0.44 % organic carban, low nitrogen, medium phosphorus and high potassium content. Experiment was laid out in Randomized Block Design (RBD) with three replications. The result of experiments indicated that the treatment Penoxsulam + Pendimethalin (10+240 g/l) SE @ 100 + 2400 g a.i. ha⁻¹ (T₅) registered maximum growth characters of rice like plant height, dry matter, number of tillers, leaf area, leaf area index, CGR.
