Abstract
It has long been recognized that humic substances have many beneficial effects on soil and plant growth. These heterogeneous and complex molecules, ubiquitous in the environment, can produce various morphological, physiological and biochemical effects on higher plants. In order to determine, the effect of Humic acid on nutrient uptake by cucumber an investigation with cucumber cultivar 'Rubah-R' was conducted in a glass greenhouse in 2008 in the Agricultural Faculty of Guilan University, Rasht, Iran. Results showed that humic acid did not affect fruit, root and leaf dry matter of cucumber. Humic acid significantly affected yield attributes. Plant yield was higher when plants were treated with complete nutrient solution. Humic acid have significant effect on nutritional elements uptake by cucumber and as a result we can decrease element content in nutrient solution due to this humic acid positive effect.
