Abstract: 

The research was carried out in Agricultural Scientific Research Center in Jableh- sanopar area in sandy soil (2020-2021), using eggplant plants (variety Nawair), in order to study the effect of hydrogel addition (0,1-0.2-0.4 g/hole) to sandy soil on water conservation and plant growth indicators. The results were subjected to statistical analysis using the Genstat 12 program, and a nova test to calculate LSD at 5%. Laboratory analysis of hydrogel treatment (0.1-0.2-0.4%) of sandy soil resulted in an increase in moisture content and delayed the water time loss from the soil. Field capacity increased steadily with increasing hydrogel concentration, which enhanced the amount of available water. Leaf and flower number, leaf area, branch, and root dry weight were significantly increased compared to the control. Treatment of sandy soil with hydrogel (0.1-0.2-0.4 g/hole) at field, reduced the amount of water needed to produce 1 kg of eggplant compared with the control, 0.4 g/hole was superior compared to the author treatments.

Keywords: eggplant, hydrogel, polymer, sandy soil, moisture content.
