Abstract: A field experiment was conducted at the Wetlands Farm of Department of Farm Management, Tamil Nadu Agricultural University to evaluate the effect of different chemical and non-chemical weed management practices on the growth of aerobic rice. Pre emergence (PE) application of pendimethalin (1.0 kg ha^-1) on 3 DAS + Early post emergence (EPOE) application of bispyribac sodium (25 g ha-1) on 20 DAS significantly higher leaf area index, drymatter production, crop growth rate and SPAD values. This sequential application of pendimethalin and bispyribac sodium recorded 61.11 per cent increased dry matter over weedy check at maturity. Meanwhile growing intercrops as living mulch showed promising results for using it as a component of integrated weed management practice.
