| Two field experiments were conducted on a the clay saline sodic soil in El-Rowad Village Farm in Sahl El-Hossinia, El-Sharkia Governorate, Egypt, during summer 2014 and winter season 2014/2015 to study the effect of two different drains type (open drain and covered drain system) with different depths of 50, 70 and 90 cm from surface soil on some soil chemical properties , maize , wheat productivity and water use efficiency (WUE) under sodic saline soil condition to select the best drain system with the best drain depth. Results showed that using open and covered drains decreased soil pH and EC of soil with drain depth (50 and 70 cm from surface soil) more than drain depth 90 cm. In addition, the effect of applying open drain system with drain depth of 50 and 70 cm show that positive increase in available N, P, K, Fe, Mn and Zn in saline sodic clay soil compared with depth 90 cm under open drain system. Concerning the weight of straw yield, grain yield (Mg/fed) and weight of 1000 grain (g) for both maize and wheat were significant increase with open drain for 50 cm depth more than 70 and 90 cm depth. Finally, the using of open drain system with lowest depth treatment produced maximum yield and WUE value with cultivation both maize and wheat crops. The using of open drain system with 50 cm depth lead to improve the soil chemical properties of clay saline sodic soil and increase the yield productivity and water use efficiency (WUE) of maize and wheat crops. | ||||
