Efficacy of new herbicide (bispyribac sodium 10% SC) against different weed flora, nutrient uptake in rice and their residual effects on succeeding crop of green gram under zero tillage
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 1
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.
