The main purpose of this work was evaluate the effect of moringa oleifera leaf extract; MLE on improving of some chemical properties and macro-nutrients  of salt affected loamy sandy  soils , Evaluate the effective role of applied moringa oleifera leaf extract; MLE as solely in combined treatments on the tolerance of  sun flower  plants grown under a slight soil salinity condition and Evaluate these amendments economically. From the obtained result, of this experiment it could be concluded that: A.They improved the physiological properties of sunflower plants in salt affected soil. B.Application of T3 = MO steep + MO  spray gave the highest increase of sun flower yield. C.The results showed that the top two practical and economic parameters of the field experiment were (T1 and T3) respectively where the increase values of macro-nutrients ( N, P and K) vs decr
