Abstract
A field experiment was conducted at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during Kharif season of 2021. To evaluate the effect of different doses of Mesotrione 2.27% w/w + Atrazine 22.7% w/w SC on growth and yield of maize (Zea mays L.). The experiment was laid down in the Randomized block design with ten treatments which was replicated three times. Experimental Field was infested with Echinochloa colona, Digitaria sanguinalis, Dactyloctenium aegyptium, Commelina benghalensis, Trianthema and Cyperus rotundus. Ready-mix herbicide, Mesotrione 2.27% w/w + Atrazine 22.7% w/w SC (Calaris Xtra) manufactured by Syngenta was used in the experiment. Among the herbicidal treatments, the application of Mesotrione 2.27% w/w + Atrazine 22.7% w/w SC @ 1.750 kg a.i. ha-1 recorded the lowest weed density and highest weed control efficiency (approx. 90%) at every growth stage of maize. However, among herbicidal treatments, grain yield of maize was maximum with the application of Mesotrione 2.27% w/w + Atrazine 22.7% w/w SC @ 1.0 kg a.i. ha-1(T4) which might be due do toxicity effect of herbicide.
