We want to describe and introduce some traditional methods for growing crops with minimum irrigation and even with no irrigation, once practiced in the Iranian desert. We have classified these methods into three categories as follows: 1- thorn-based cultivation: in this method such crops as cucumber or watermelon can live off the moisture being secreted out from the vascular system of some desert plants. 2- pottery irrigation: in this method the crop can be irrigated just by the minimal water seeping through a clay membrane into the soil according to osmotic pressure. 3- flood irrigation: the flash floods can be controlled and harvested behind the earthen dams in order to increase the soil moisture. Some crops can be grown behind the dams after the water would percolate the earth.
