Abstract:

A field experiment was conducted during kharif 2012 to evaluate the efficacy of different pre and post emergence herbicides in direct seeded rice. The chemical treatments included two pre-emergence herbicides namely pendimethalin 1000 g/ha and oxadiargyl 100 g/ha and four post-emergence herbicides viz. bispyribac-sodium 25 g/ha, fenoxaprop 67 g/ha, ethoxysulfuron 18.75 g/ha and chlorimuron-ethyl +metsulfuron-methyl RM 4 g/ha at 25 DAS. Weed free and weedy check were also included. Among chemical treatments, sequential application of pendimethalin 1000 g/ha fb bispyribac-sodium 25 g/ha and chlorimuron-ethyl+ metsulfuron-methyl RM 4 g/ha produces minimum density of Echinochloa glabrescens, Cyperus spp. and Ammania spp. at 45 DAS which was statistically at par with weed free. This treatment also had highest efficacy against Echinochloa glabrescens, Cyperus spp. and Ammania spp. at 45 DAS. Sequential application of pendimethalin 1000 g/ha fb bispyribac-sodium 25 g/ha and chlorimuron-ethyl+ metsulfuron-methyl RM 4 g/ha gave maximum number of effective tillers (209.3), filled grains/panicle (83.7), grain yield (3.97 t/ha) and B:C (2.37) among chemical weed control treatments which was at par with weed free.


Keywords: Direct seeded rice, effective tillers, filled grains, grain yield, herbicides, weed control efficiency.
