Abstract:
The research was carried out in Deir Ezzor Governorate, Marat village, during the two seasons (2020-2021) according to a split plot design with three replications, to study the effect of using foliar spraying with humic acid on some characteristics of vegetative growth and productivity of cucumber crop. Four concentrations of humic acid were used (0 , 1000 , 2000 , 3000 ppm) and five levels of ground mineral fertilization with major elements N.P.K (0, 25, 50, 75, 100) %. according to the quantities recommended by the Ministry of Agriculture and Agrarian Reform for the cucumber crop. The results showed that spraying humic acid at a concentration of (3000ppm) ppm achieved a significant increase in all the characteristics of vegetative growth and productivity, while the level of mineral fertilization (100%) was significantly superior to all other levels in the characteristics of vegetative growth and productivity. As for the interaction between them, the treatment was superior)3000 ppm X 100%) significantly for all the studied reactions in most productive traits, followed by the treatment (3000 ppm X 75%), where the total productivity of the two reactions reached (5617.1-4623.2 kg / d). so Foliar Spraying With an Humic Acid is recommended 3000ppm with addition mineral Fertilizer 100% to get an increase in all the characteristics of vegetative growth and productivity per unite area.
Keywords: Humic acid,(Cucumis. sativus L), Mineral fertilization, Vegetative growth, productivity.
