Abstract

Regarding the scarcity of water resources in arid regions of the world, using more efficient irrigation systems is essential in agriculture. Possible option for improving agricultural water productivity is the irrigation method using steam- pottery system. This study introduces a new method of pottery irrigation system that is capable of transferring moisture and nutrients into the soil. The experimental system consisted of two clear plexiglasses with the dimension of 130 × 40 × 40 cm. The clay pipes were used in each of the boxes had the same dimensions (length 90 and diameter 5 cm). Perlite-coco peat is used as a soil. The volumetric moisture content of the soil was measured by using an analog moisture meter. The data recorded by the sensors were analyzed in both the steam-pottery system, and the water-pottery system. The results show that the distribution of moisture is uniform for both of them, in terms of time and space. However, the amount of moisture in the steam-pottery system is less than water-pottery system. The result is that in the steam-pottery system, the water demands of the plant are met, with total water use less than it was in the water-pottery system.  Other advantages of the steam-pottery system over the water-pottery system are that the pipes are not clogged and their service life is greatly extended
