Abstract
An experiment was conducted at the Students Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, India during summer season of 2018 to find out the most effective pre- and post-emergent herbicide combination for effective management of weeds in blackgram. Experiments consisted of ten treatments. The lowest weed density and biomass, weed index and highest weed control efficiency and blackgram yield as well as B:C ratio was observed with pre-emergence application (PE) of pendimethalin 1000 g/ha followed by post-emergence application (PoE) of imazethapyr 50 g/ha which was effective and economical in managing weeds in blackgram
