Abstract
Field experiments were conducted at ICAR Krishi Vigyan Kendra, Valikandapuram, Perambalur district of Tamil Nandu during kharif 2017 to study the response of maize hybrids to varied plant densities and weed control methods under irrigated condition. The experiments were laid out in split-plot design replicated three with five main treatments viz., M 1 -Maize sole crop, M 2 -Maize + blackgram, M 3 -Maize + cowpea, M 4 -Maize + soybean and sub plot treatments viz., S 1 -Un weeded check, S 2 -Hand weeding (Two times) 20 and 40 DAS, S 3 -Alachlor @ 0.2 kg /ha as pre emergence + Twin wheel hoe on 30 DAS, S 4 -Alachlor @ 0.2 kg /ha as pre emergence + one hand weeding on 30 DAS, S 5 -Alachlor + Post emergence tembotrione on 21 DAS. From the results, it is concluded that maize + cowpea (M 3 ) along with S 3 -Alachlor @ 0.2 kg /ha as pre emergence + Twin wheel hoe on 30 DAS was recorded the lower weed density and weed control efficiency and the highest growth parameters, yield parameters and yield and proved to be an efficient and economically feasible technology to manage the weeds and to realize better returns from the irrigated hybrid maize.
