Abstract: The experiment was conducted at the Agronomy Research Farm of N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during the Kharif season of 2015-16, to evaluate the effects of pre-emergence and post-emergence herbicides on the growth and yield of Urdbean (Vigna mungo L.). Twelve weed management treatments were tested, including: Imazethapyr 70 g ha⁻¹ PRE, Imazethapyr 80 g ha⁻¹ PRE, Imazethapyr 70 g ha⁻¹ POE (3-4 leaf stage of weeds), Imazethapyr 80 g ha⁻¹ POE (3-4 leaf stage of weeds), Imazethapyr + imazamox (RM) 70 g ha⁻¹ PRE, Imazethapyr + imazamox (RM) 80 g ha⁻¹ PRE, Imazethapyr + imazamox (RM) 70 g ha⁻¹ POE (3-4 leaf stage of weeds), Imazethapyr + imazamox (RM) 80 g ha⁻¹ POE (3-4 leaf stage of weeds), Pendimethalin 1000 g ha⁻¹ PRE, Imazethapyr + Pendimethalin (RM) 1000 g ha⁻¹ PRE, Hoeing (20 & 40 DAS) and a Weedy check. The results showed that the pre-emergence application of imazethapyr + pendimethalin at 1000 g ha⁻¹ was the most effective treatment, improving the growth parameters and grain yield of urdbean. This was followed by imazethapyr + imazamox (RM) at 80 g ha⁻¹, imazethapyr + imazamox (RM) at 70 g ha⁻¹, and pendimethalin at 1000 g ha⁻¹. The post-emergence application of imazethapyr + imazamox (RM) at 80 g ha⁻¹ produced significantly higher grain yield compared to the other treatments.
