e0“A field experiment was conducted during Rabi season of 2015-2016 at Agricultural College and Research Institute, Killikulam to find out the most effective weed control measure study weed dynamics, productivity and economics of hybrid maize as affected by integrated weed management”
e4“Significantly highest grain yield were recorded underalachlor @ 1.5 kg a.i./ ha + HW at 30 DAS (7115 kg ha-1) followed by two hand weedings at 15 and 30 DAS (6855 kg ha-1) and mechanical weeding with power weeder twice on 15 and 30 DAS(6714 kg ha-1)”
