Relative Efficacy of Different Weed Management Practices on Growth, Yield and Weed Dynamics in Sunflower

摘要

The experiment was conducted during 2020 to evaluate the relative efficiency of the application of herbicides combined with inter cultivation practices for their influence on the growth and productivity of sunflower. Herbicides like pendimethalin, oxyfluorfen, sodium aciflurfen, clodinafop propargyl with intercultivation at different days after sowing and un weeding as control. Pendimethalin @ 0.75 kg/ha at 1 DAS followed by Sodium aciflurofen + Clodinafop propargyl @ 125 g/ha at 21 DAS proved to be better in terms of effective weed control, improved crop growth characters, and productivity of sunflower. The performance of Oxyfluorfen @100 g/ha at 1 DAS fb Sodium aciflurofen + Clodinafop propargyl @150 g/ha at 21 DAS was on par with Pendimethalin @ 0.75 kg/ha at 1 DAS followed by Sodium aciflurofen + Clodinafop propargyl @ 125 g/ha at 21 DAS with regard to growth, yield attributes and seed yield.
