Abstract

The present investigation was conducted at Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during kharif season 2023. The experiment was laid out in Randomized Block Design with eight different treatments viz. T1: Weedy check (control). T2:  Pre-emergence application of pendimethalin @6ml/L. T3:  Postemergence application of metribuzin @525g/ha. T4: Pre-emergence application of pendimethalin @6ml/L. + 1 hand weeding at 40 DAS T5:  Postemergence application of metribuzin @525g/ha at + 1 hand weeding at 60 DAS. T6: Pre-emergence application of pendimethalin @6ml/L.+ Postemergence application of metribuzin @525g/ha+ One hand weeding 40 DAS., T7: Pre-emergence application of pendimethalin @6ml/L.+ Postemergence application of metribuzin @525g/ha, T8: .Weed free check {three hand weeding} at 20,40,60 DAS respectively, replicated thrice. The okra variety ‘Azad Bhindi-1’ was used in experiment. The result of the study revealed that at 30 DAS maximum plant height (30.10cm) was reported in treatment T6, and 60 and 90 DAS maximum plant height (76.50 and 110.00 cm) was reported in T8 and at 30 days maximum number of nodes on main stem of plant (8.70) found in T6, whereas at 60 and 90 DAS maximum number of nodes on main stem of plant (17.80 and 20.50) was reported in T8 . At 30 days maximum diameter of stem(1.30 cm) was reported in treatment T6 , and at 60 and 90 DAS maximum diameter of stem(1.90 and 2.50 cm) reported in T8, at 30 days maximum number of leaves/plant  (8.80) is reported in T6 and at 60 and 90 days maximum number of leaves/plant (2.27 and 4.76) is was reported in T8. At 60 and 90 DAS Maximum number of branches per plant (4.90 and 5.96) was found in T8 Maximum Pod diameter (1.80 cm), fruit weight (13.55 gm), pod length (14.30 cm), number of pods per plant ( 25.74 ), pod yield per plant ( 285.00 gm) , pod yield per hectare (16.50 t), TSS ( 3.18 0Brix), crude fibre (8.65 %) and chlorophyll content (1.22 mg) and maximum BCR (1:2.60) were reported in T8.
