Weed Management in Shaftal (Trifolium resupinatum) Under Mid Hill Conditions of Himachal Pradesh

Pendimethalin at 1.25 kg ha⁻¹ gave better control of weeds with weed control efficiency of 92.9% and produced significantly higher green forage yield (19.7 t ha⁻¹) and remained at par with butachlor at 1.50 kg ha⁻¹ (19.1 t ha⁻¹). Higher doses of herbicides gave better conttol of weeds but proved toxic to crop and caused significant reduction in forage yield. Butachlor at 1.50 kg ha⁻¹ resulted in highest net return of Rs. 11,511 ha⁻¹ and remained at par with pendimethalin at 1.25 kg ha⁻¹ (Rs. 10,983 ha⁻¹).
