Economics of integrated weed management practices in Rabi hybrid maize (Zea mays)

Author(s): R. Nagasai Vardhan Naik and A. Velayutham
Abstract: An experiment was conducted during rabi season of 2015-2016 at Agricultural College and Research Institute, Killikulam to study the effect of weed management on yield and economics of maize. Weed management has positive influence on growth, yield attributes and yield of maize. Maximum highest grain yield were recorded under alachlor @ 1.5 kg a.i ha-1 + HW on 30 DAS (T2) (7115 kg ha-1) and was statistically at par with grain yield obtained by two hand weedings on 15 and 30 DAS (T10) (6855 kg ha-1) and mechanical weeding with power weeder twice on 15 and 30 DAS (6714 kg ha-1). The highest net returns and highest B:C ratio were obtained under alachlor @ 1.5 kg a.i ha-1 + HW at 30 DAS (T2) followed by two hand weedings on 15 and 30 DAS (T10). Alachlor @ 1.5 kg a.i ha-1 + HW at 30 DAS proved equally effective in increasing most of the growth parameters, yield attributes, yield and economic advantage.
