Effect of live mulches and herbicides on weeds and yield of direct-seeded rice under irrigated conditions

A field experiment was conducted at Mata Gujri College, Fatehgarh Sahib, Punjab during rainy season of 2017 to study the effect of live mulches and herbicides in direct-seeded rice under irrigated condition. The experiment was laid out in a split-plot design with three replications. The live mulch include Sesbania rostrata, Vigna unguiculata and Sesamum indicum while weed management treatments were pendimethalin 1.0 kg/ha (PE) fb bispyribac-Na 25 g/ha (PoE), bispyribac-Na 25 g/ha + carfentrazone 20 g/ha (PoE), bispyribac-Na 25 g/ha + ethoxysulfuron 18 g/ha (PoE) and pendimethalin 1.0 kg/ha (PE) along with weed free and weedy checks. Results indicated that higher yield attributes and yield were recorded under live mulch with Sesbania rostrata, which was statistically at par with live mulch with Vigna unguiculata and significantly superior over live mulch with Sesamum indicum. Among herbicides, application of bispyribac-Na 25 g/ha + carfentrazone 20 g/ha being at par with bispyribac- Na 25 g/ha + ethoxysulfuron 18 g/ha was significantly superior over other treatments.
