Effect of Mesotrione 40% SC on Weed Growth, Yield and Economics of Maize (Zea mays L.)

Newer herbicides are required to reduce the losses cause by weeds in maize crop. Therefore, a field experiment was conducted during kharif 2019 at Research Farm, AICRP on Forage Crops, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (Madhya Pradesh) study effect different weed management practices productivity Maize (Zea mays L.). The randomized block design with eight treatments (six herbicidal hand weeding twice 20 and 40 DAS weedy check) replicated thrice. Observations were recorded for various parameters crop growth parameters. All significantly reduced total density dry weight as compared check. Among treatments, mesotrione 350 g ha-1 lowest other herbicides. While highest under check treatment. Significantly higher yield attributing traits application which resulted grain stover yields (2447.22 21804.72 kg ha-1) followed 300 ha-1. Maximum net returns Benefit: Cost ratio also obtained
