An experiment to study the effect of humic acid (0, 10, 20, 30 and 40 kg ha-1) on okra cultivars (Sabz Pari, Green Star, Arka Anamika and Pusa Sawani) was carried out at Dargai, District Malakand during 2015 in randomized complete block design with three replications. It was observed that maximum emergence percentage (74.53), single pod weight (14.27 g), stem diameter (19.01 mm), plant height (129.17 cm), number of branches plant-1 (5.34) and maximum yield (12.85 tonnes ha-1) was produced by cv. Arka Anamika. Non-significant effect of humic acid was noticed on emergence percentage and number of branches plant-1 while significantly maximum pod weight (13.79 g), stem diameter (19.29 mm), plant height (129.39 cm) and yield (12.63 tonnes ha-1) was recorded when humic acid was applied @ 20 kg ha-1. On the basis of current study it is concluded that cultivar Arka Anamika performed will under the agro climatic conditions of Dargai as compared to other tested cultivars therefore better growth and higher yield humic acid should be amended @ 20 kg ha-1 under the agro climatic conditions of Dargai, District Malakand, Khyber Pakhtunkhwa-Pakistan.
