The research was conducted in Sfia village of hassaka during 2016 and 2017 seasons. RCBD design with three replications was used. The Aims was Effect Of Spray By Humic Acid On Early Characters And Yield Of Babylon Cucumber Variety (Cucumis Sativus L.) in different growth stages. By three sprays in the four real paper stage with one spray over 10 days, by average three of humic acid (500, 1000, 1500) ppm. 

The Aim of studying: humic acid was using by average (1000, 1500) ppm spray on cucumber leafs showed maturity early. Where was (32, 30.33) day respectively for trait of male flower one show and (35.67, 34) day respectively for trait of female flower one show and (45, 43.33) day respectively for trait of first mature. There was a significant increase compared with or to other treatments for mature early traits. And was a significant increase compared with or to other treatments for most productivity traits, where was (93.67, 97) g. respectively for fruit weight, and (3600, 4230)kg/d. respectively for productivity. 

Key words: humic acid, cucumber, early traits, productivity.
