SUMMARY
A field experiment was conducted on sandy clay loam soil from March to July 2022 to study the weed control efficiency of Sulfentrazone and its effect on yield parameters and yield of fodder maize at Pandit Jawaharlal Nehru College of Agriculture and Research Institute (PAJANCOA & RI), Karaikal. The experiment included sixteen treatments comprising sulfentrazone applied with six doses (180, 210, 240, 270, 300, and 360 g/ha) on the day of sowing and 3rd DAS. It also included the application of atrazine (250 g/ha), hand weeding twice at 20 and 40 DAS (farmer’s practice), weed- free throughout the crop growth, and unweeded control (without weed management). The experiment was statistically tested using a Randomized Block Design with three replications. From the present study, it was concluded that the effective and economical control of weeds with higher seed yield of fodder maize was obtained by the application of Sulfentrazone 39.6% (w/w) SC @ 180 g a.i./ha on the day of sowing or 3rd DAS.
