The present experiment entitled "Effect of Foliar Application Humic Acid on Growth, Yield and Quality of Okra (Abelmoschus esculentus L.)" was undertaken at Horticulture Research Farm, Department of Horticulture, Chandra Bhanu Gupta Agriculture Post Graduate College, Bakshi Ka Talab, Lucknow during Kharif season of 2023 & 24. The study was consisted for six treatments of Humic Acid levels (control, 0, 5, 10, 15, and 20 ml/l). The experiment was laid out in Randomized Block Design and replicated three times. The results revealed that significantly higher Plant Height (cm), Number of Flowers per plant, Number of Fruits per Plant, Average Fruit weight (g), Fruit Length (cm) and Fruit yield (q/ha), while minimum Days to 50% Flowering, Days to First Fruit Set (Days), Days to First Fruit Picking (Days) were recorded with treatment of T5 (100% RDF + foliar spray of Humic Acid 15ml/l).
