Humic acid is an organic substance which is beneficial to both soil and plants which possess phytohormone like activity. The present study was conducted to test the effect of different levels of humic acid by soil application and foliar spray either alone or in combination on growth and yield of okra cv. Arka Anamika. The experiment was carried out at Department of Horticulture, Gandhi KrishiVigyana Kendra, University of Agricultural Sciences, Bangalore during rabi season of 2019-20 and this experiment was laid out in Randomised Complete Block Design (RCBD) with 9 treatments and 3 replication at spacing of 60 cm Χ 30 cm between the rows and plants. Two levels of humic acid (10 ml, 15 ml) applied as a soil drench at the time of sowing, foliar spray at 30 days after sowing and in combination of both was imposed. The results of the investigation revealed that, the treatment combination with soil application of HA 15 ml/l + foliar application of HA 15 ml/l (T9) recorded significantly higher plant height, more number of leaves and branches, highest leaf area and highest chlorophyll content in the leaves.
