A field experiment was conducted to determine the effect of foliar application of Humic acid on growth, yield and quality of Okra (Abelmoschus esculentus L.) cv. Arka Anamika. The experiment was carried out at Horticulture Research Centre, Chauras Campus, H.N.B. Garhwal University, Uttarakhand (India), in Randomized Block Design with three replications. 16 treatments were used during the experiment which consists of fifteen different concentration of humic acid viz., 10ml, 20ml, 30ml, 40ml, 50ml, 60ml, 70ml, 80ml, 90ml, 100ml, 110ml, 120ml, 130ml, 140ml, 150ml and control. Seventeen growth and yield characters were studied during the experiment viz., days taken to full germination, plants height (cm), number of primary branches, length of leaf (cm), width of leaf (cm), leaf area index (cm3), number of leaves, days taken to first flowering, number of flower per plant, days taken to first fruiting, number of fruit per plant, fruit length (cm), fruit diameter (cm), dry weight of leaves (g), dry weight of plant (g), total yield (ha) and vit. C. The results were found to be significant in most of the growth, yield and quality contributing characters of okra like days taken to full germination (22.33 days) were found maximum in T16 (control). Plant height T15 (208.34 cm), number of leaves per plant T15 (31.80), leaf length T15 (24.67cm), width of leaf T15 (22.87 cm), dry weight of leaf T15 (24.79 g), leaf index T15 (447.99 cm3), number of flower per plant T15 (31.13), days taken to first fruiting T16 (44.33), number of fruit per plant T15 (23.13), fruit length T15 (13.20 cm), yield per ha1 T15 (122.0 q) and vitamin C T15 (22.33 g) were found maximum in treatment T15 (150 ml/litre) and fruit diameter (1.54 cm) were found maximum in T7 (70ml/ litre). Three characters of okra showed the non-significant difference among viz., number of primary branch, days taken to first flowering and dry weight of plant. The obtained results clearly indicated that using the foliar application of humic acid T15 (150ml L-1) significantly increased plant growth, yield and quality parameters compared to control.
