In order to investigate the water requirement of plants, especially in arid and desert areas and the poverty of most soils in these areas, we conducted a pot experiment to study the effect of the absorbance hydrophilic polymer on Panicum antidotale Retz. with its effect on nitrogen leaching in three types of light, medium and heavy soils in irrigation intervals of 4, 8 and 12 days. Comparison of results with control treatment showed that application of polymer that was carried out at 0.3% has the highest effect on the growth and dry matter production of Panicum antidotale Retz.The simple effect of polymer treatments, the irrigation interval and the soil texture on dry matter production, plant height, and nitrogen leaching from the soil were significant in this study. Also, the interaction effects of irrigation × soil texture on dry matter production, and nitrogen leaching showed a significant difference. So that the highest amount of dry matter of plant with 7.2 g was obtained from medium treatment with polymer in irrigation interval of 4 days. In the control treatment without the polymer, the plants were destroyed before harvest in the irrigation interval of 12 days. The effect of treatments on Panicum height indicated that the addition of polymer to the soil would increase the height of the Panicum besides increasing dry matter production. Also, the effect of simple polymer in irrigation water drain indicated that the nitrogen leaching rate from the average of 880 mg N/I of in the control decreases to about 550 mg N/I by the polymer.

Therefore, it can be concluded that application of polymer not only influences soil moisture but also affects soil strengthening and decreasing nitrogen leaching, especially in desert poor soils.
