Abstract:
The field experiment was conducted during Kharif 2019 at Experiment farm of Agronomy Department, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. To study ‘Effect of Weed Management Practices on Growth and Yield of Maize (Zea mays L.)’. The experiment was laid out in a randomized block design with twelve treatments and three replications. In the field experiment chemical weed management practices Pre and Post emergence herbicides treatments viz.; treatment (T1) PE Atrazine @ 0.50 kg a.i./ha + 1HW+ 1Hoeing at (6WAS), (T2) PE Atrazine @ 0.75 kg a.i/ha + 1HW + 1Hoeing at (6WAS), (T3) PE Atrazine @ 0.50.kg a.i /ha, (T4) PE Atrazine @ 0.75 kg a.i /ha, (T5) POE 2,4-D (sodium salt) @ 1.0 kg/ha at 20 DAS + 1HW+1 Hoeing at (6WAS), (T6) POE 2,4-D (Sodium salt) @1.0 kg/ha at 20 DAS, (T7) POE Tembotrione @ 110 g/ha at 20 DAS, (T8) POE Tembotrione @ 120 g/ha at 20DAS, (T9) POE Tembotrione @ 130 g/ha at 20 DAS, (T10) 1 Hand weeding+1 Hoeing, (T11) Weed free and (T12) Weed check. Results indicated that the Weed free and PE Atrazine @ 0.75 Kg a.i/ha+1 Hand Weeding + 1Hoeing at (6WAS) was found significantly superior over the rest of treatments in respect of growth, yield and yield attributes.
