The experiment was carried out at the Wetlands Farm of the Department of Farm Management, Tamil Nadu Agricultural University, India. Pre emergence (PE) application of pendimethalin (1.0 kg ha -1 ), EPOE of bispyribac sodium (25 g ha -1 ) and EPOE of chlorimuron ethyl + metsulfuron methyl (4 g ha -1 ) were the chemical weed management practices. Daincha intercropping (1:1) fb spreading on 30DAS, Cowpea intercropping (1:1) fb spreading on 30DAS, Coir pith mulching (5 tons ha -1 ) on 3 DAS, Shredded coconut waste mulching (5 tons ha -1 ) on 3 DAS along with the combination of mechanical and hand weeding were the non chemical weed management practices. Pre emergence (PE) application of pendimethalin (1.0 kg ha -1 ) on 3 DAS fb Early post emergence (EPOE) application of bispyribac sodium (25 g ha - 1 ) on 20 DAS recorded significantly higher growth and yield attributes. Sequential application of pendimethalin and bispyribac sodium recorded 4128 kg ha -1 grain yield which was nearly 60 per cent increased over the weedy check. Coir pith mulching @ 5 tons ha -1 on 3 DAS recorded significantly lower grain yield (1840 kg ha -1 ) over the rest of the treatments. Original Research Article
