Studies on integrated weed management in onion (Allium cepa L.)

Effective weed control was attained under oxyfluorfen 0.26 kg a.i./ha with hand weeding (30 DAT), followed by oxyfluorfen 0.26 kg a.i./ha + oxyfluorfen 0.26 kg a.i./ha (30 DAT). The same treatments showed higher weed control efficiency (97.11 and 96.66% respectively) and lower weed index (3.57% and 33.48% respectively). Significantly higher weed growth was recorded in un-weeded control, with lower weed control efficiency and higher weed index.
