Abstract
The research was carried out during kharif season of 2012-13 to find out the cost-effective weed management practices with
special focus on fine tuning the dose and time of herbicide application,and its impact on growth and yield of pigeonpea at
Bihar Agricultural University, Sabour, Bhagalpur. The result of the study revealed that uncontrolled growth of weeds led to
40.53% reduction in pigeonpea yield in comparison with the other treatments. However, the highest seed yield (2,725 kg/ha)
was obtained in weed free treatment but not cost-effective due to high cost in manual weed operation. Among the herbicide
treatments, lower weed index (7.25%) was recorded in T2 (imazethapyr @ 40 g a.i./ha at 15 DAS), which resulted in higher
seed yield (2,526 kg/ha), net returns (? 71,059/ha) and benefit: cost ratio (2.74).
