Efficacy of herbicides in transplanted, medium-duration rice (Oryza sativa) under sub-tropical conditions of Jammu

Abstract

A field experiment was conducted during the rainy season of 2001 and 2002 on sandy-loam soils of Jammu, to test the efficacy of different herbicides in transplanted, medium-duration ‘PC 19’ (‘Tawi’) rice. Herbicide combinations, viz. anilophos + ethoxy sulfuron (0.312 + 0.015 kg/ha) applied 10 days after transplanting (DAT) or metsulfuron-methyl + chlonimuron ethyl + butachlor (0.004 + 0.938 kg/ha applied 3 DAT) or butachlor followed by (fb) metsulfuron-methyl + chlonimuron ethyl (0.938+0.004 kg/ha applied 3 DAT fb 21 DAT) with a mean grain yield of 48.1, 44.3 and 45.6 q/ha, respectively, remained at par with 2 hand-weedings (20 and 40 DAT). However, through improvement in weed-control efficiency corresponding mean values being 69.6, 60.8 and 61.5%, enhanced the grain yield significantly by 67.6, 54.4 and 58.9%, respectively, over control. Among the herbicides, combination of anilophos and ethoxysulfuron proved most profitable with net returns of Rs 14,268/ha and benefit: cost ratio of 1:97.
