Efficacy of pre and post emergence herbicides on weed flora of urd bean under rainfed subtropical Shiwalik foothills of Jammu & Kashmir

An experiment was conducted during rabi seasons of 2006 and 2007 at Pulses Research Sub-Station Samba, SKUAST-Jammu to study the efficacy of pre and post emergence herbicides in controlling weed flora of urd bean (Vigna mungo L.) under rainfed subtropical conditions of Jammu. The weed free treatment produced the highest seed yield and was at par with imazethapyr 250 ml/ha (post-emergence) after 15–20 days sowing. However, among the other treatments, pendimethalin (pre-emergence) 1.0 kg/ha fb 1 HW at 30 DAS was found superior in controlling the weed flora and increasing the seed yield. Unweeded check produced the lowest seed yield.
