Sandy soils are well known as being droughty, erodible, infertile and non economical. The main objective is to vegetate the desert with a water consumption as low as possible. Two field experiments were conducted during 2012/2013 and 2013/2014 seasons. The experiments were carried out in Developing Agricultural System Project, Sinai Station, Sinai Governorate to study the effect of' nanoclay flakes treatments on revegetation of sandy soil under sprinkler irrigation system with Egyptian clover var Gemmiza 1. The experiments were designed as a split-plot design with four replications, the main plots included the source of irrigation dates after 3, 5, 7 and 9 days, the subplot had nanoclay doses (0, 8.5, 17 and 25 kg/plot) at soil depth 10 cm. The results indicated that the water requirement for the Egyptian clover ranged from 2800-3000 m 3 /fed of water depending on climate and the growing period, Evaportranspiration increases from establishment of flowering stage (5-7mm/day), the irrigation interval of 7 days showed the highest forage yield, the dose of 17Kg/plot nanoclay flakes had significant effect on forage yield. Also, the obtained results revealed that yield components have been increased due to the nanoclay treatment with high significancy compared to the untreated area by increasing the availability of water for crop use by 50%. Treating the sandy soil with clay nano flakes resulted in significant differences in Egyptian clover yield and led to increasing the nitrogen, phosphorus, potassium, contents and decreasing the water consumption rate by 50%.
