abstract
A field experiment entitled “Studies on effect of post-emergence herbicides for weed management in maize” was carried out during kharif, 2022 at Main Agriculture Research Station, University of Agricultural Sciences, Raichur, Karnataka, India. The experiment was laid out in Randomized Complete Block Design with three replications and eleven treatments. The results of the experiment revealed that weed free check had recorded significantly higher growth parameters viz., plant height number of leaves per plant, leaf area, leaf area index and total dry matter production in maize. Among the herbicide treatments, application of mesotrione 48% SC @ 144 g a.i. ha-1 at 3-4 leaf stage of weeds fb IC at 45 DAS had resulted in higher growth parameters which was statistically on par with mesotrione 48% SC @ 120 g a.i. ha-1 at 3-4 leaf stage of weeds fb IC at 45 DAS, tembotrione 34.4% SC @ 125 g a.i. ha-1 at 3-4 leaf stage of weeds fb IC at 45 DAS and farmers’ practice wherein hand weeding was carried out at 20 DAS followed by IC at 40 DAS. Hence, mesotrione 48% SC @ 120 g a.i. ha-1 at 3-4 leaf stage of weeds fb IC at 45 DAS could be used as an effective weed management practice in maize.
