Abstract : Field experiment was conducted in the wetland farms of Tamil Nadu Agricultural University,
Coimbatore during rabi season (August to February) of 2011-12 to evaluate the herbicide (Bispyribac sodium 10% SC) on weed control
and their nutrient management in direct seeded lowland rice. The experiment was laid out in a Randomized Block Design (RBD) with three
replications. The results revealed that Early Post Emergence (EPOE) application of bispyribac sodium 10% SC 40 g ha-1 recorded higher
weed control efficiency and lesser weed density, nutrient uptake at reproductive stage of the crop. Different weed management practices
imposed on rice crop did not affect the germination of succeeding green gram.
