Effect of weed management to enhance the productivity of zero tillage maize grown in rice fallow condition

Abstract

A field experiment was conducted at the Annamalai University, Department of Agronomy, Faculty of Agriculture, Annamalai Nagar during winter season of 2018 to study weed management practices for enhancing productivity of zero tillage maize grown under rice fallow conditions.. The trial was fitted in randomized block design with three replications there were altogether ten weed control treatments. Weed management practices result shows significantly when application of paraquat 0.6 kg ha^-1 immediately after dibbling of seeds followed by hand weeding on 30 DAS recorded the lowest weed density, weed biomass and higher weed control efficiency. Yield attributes and yield of maize was significantly higher with application of paraquat 0.6 kg ha^-1immediately after dibbling of seeds followed by hand weeding on 30 DAS and it was on par with hand weeding twice at 15 and 30 DAS.
