Abstract

The research was conducted at Faculty of Agriculture in Al-Hassaka governorate during 2016 and 2017 seasons. RCBD design with three replications was used. The aim was to study the effect of spray with humic acid on morphological traits and yield of Babylon cucumber variety in different growth stages in an average of three sprays at the fourth real leaf stage, then after 10 days for each spray. Three concentrations of humic acid were used i.e. 500, 1000 and 1500 ppm. The results showed that humic acid improved morphological traits of leaves, where the leaf length reached (18.33) cm, the width was (20) cm  when humic acid was sprayed with 1500 ppm, while leaf length and width were 17.67 and 19 cm when sprayed with 500 ppm. The fruit length was (13.72 and 12.78) cm when humic acid sprayed with 1500 and 1000 ppm respectively. There was a significant increase most productivity traits when the concentrations 1000 and 1500 ppm were used compared to other treatments, where the fruit weight was (98 and 94 g) respectively, and the productivity was (4133 and 3498) kg/d respectively.

Key words: Humic acid, Cucumber, Morphological traits, Productivity.
