This study investigates the economics of different weed management practices in kharif and summer mungbean [Vigna radiata (L.)Wilczek] under the Punjab (India) conditions. The field experiments (Experiment 1 and Experiment 2) were conducted during kharif 2016 and summer 2017 with ten different weed management treatments by replicating thrice in Randomized Complete Block Design (RCBD). Application of pendimethalin 30 ECat 0.45 kg ha-1 + hand weeding (HW) at 4 weeks after sowing (WAS) and pendimethalin 30 EC + imazethapyr 2 SL (pre-mix) at 0.45 kg ha-1 + HW at 4 WAS recorded statistically similar net returns with two HW at 4 and 6 WAS during both the seasons. Application of pendimethalin 30 EC at 0.45 kg ha-1 + HW at 4 WAS, pendimethalin 30EC at 0.75 kg ha-1 and imazethapyr 10 SL at 75 g ha-1 at 15 days after sowing (DAS) recorded higher, though statistically similar, B:C ratio than with two HW at 4 and 6 WAS. Pendimethalin 30 EC at 0.45 kg ha-1 + HW at 4 WAS, pendimethalin 30 EC at 0.75 kg ha-1, pendimethalin 30 EC + imazethapyr 2 SL at 0.45 kg ha-1 + HW at 4 WAS and imazethapyr 10 SL at 75 g ha-1 at 15 DAS can act as alternative to two HW where labouris costly or not available at appropriate time for manual weeding in mungbean.
