The Study of Deficit Irrigation for Forest Plantation in Semiarid Areas

The climate situation is one of the main factors for developing of green spaces in semiarid regions, because the first priority of people for available water will be for living and agricultural products. In such big semiarid zones in the world, each year different projects are launched in order to reduction of irrigation costs and development of green spaces. The objective of this research was to find a practical way for afforestation development and optimal and viable solution for creation and irrigation of planting in semiarid zones. This research has been continued for 1 year and 4 broadleaves and 4 confers were evaluated under 5 treatments by the use of superabsorbent material, bearing the trade market as Stockosorb 300. The results of the research proved that the type of treatment which had been employed had a positive effect on the aliveness of the saplings with reduction of minimum 50% water irrigation for many species. The statistical analyses indicated tree species under treatments are significantly different that Robinia pseudoacaccia proved to be the best species and Cupressus sempervirens the worst.
