Effect of different weedicides on growth, yield and quality of okra

The present investigation entitled, “Effect of different weedicides on growth, yield and quality of okra” The field experiment was carried out during 2024-25 at Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. To study the relative performance of different herbicides for control of weeds for better growth, yield and quality of okra. The experiment was conducted in randomized block design (RBD) with three replications and eight treatments viz, T₁-Pendimethalin 38.7% as PE 1.0 kg a.i./ha fb 1HW at 30 DAS, T₂ -Oxyfluorfen 23.5% as PE 0.150 kg a.i./ha fb 1HW at 30 DAS, T₃ -Metribuzin 70% WP as PE 0.60 kg a.i./ha fb 1 HW at 30 DAS, T₄ -Propaquizofop 5% + Oxyfluorfen 12% w/w EC 0.150 kg a.i./ha as PoE at 20 DAS fb 1HW at 60 DAS, T₅-Propaquizafop 2.5% + Imazethapyer 3.75% w/w ME 0.125 kg a.i./ha as PoE at 20 DAS fb 1 HW at 60 DAS, T₆-Imazethapyer 35% + Imazamox 35% WG 0.070 kg a.i./ha as PoE at 20 DAS fb 1 HW, T₇- Farmers practice HW at 20,40,60 DAS, T₈ -Weedy Check were tested. Significantly lower density and dry matter of weeds were recorded with farmers practice of 3 HW followed by post emergence application of Propaquizofop 5% + Oxyfluorfen 12% followed by one hand weeding at 60 DAS. The average plant height, number of fruits per plant, fruit yield per plant and fruit yield per hectare were also highest in farmers practice while it was at par with Propaquizofop 5% + Oxyfluorfen 12% followed by one hand weeding at 60 DAS. The maximum B:C ratio 2.52 was obtained in combined spray of Propaquizofop and Oxyfluorfen followed by one hand weeding at 60 DAS. Post-emergence herbicide application was found to be an effective method for broad-spectrum weed management and improving economic returns in okra cultivation. Propaquizafop 5% + Oxyfluorfen 12% w/w EC at 0.150 kg a.i./ha applied at 20 DAS followed by one hand weeding at 60 DAS was the most effective treatment for enhancing growth and yield parameters.
