This investigation of both of irrigation system, water restriction and soil conditioners on Morengaoleifera, (surface drip irrigation, D, buried drip, BD and mini-sprinkler, MS), as well for irrigating a magic crop like Morenga (Morengaoleifera) plants. Also, this work includes different irrigation water restriction which represent two three treatments (100, 80 and 60% of calculated applied water, W1, W2 and W3 respectivly), more over threes soil conditioners (Compost, C, Farm manure, FM, Mud, M). The experiment was carried out inShalatien where it lies in the east-west of the Red sea in Egypt. Surface evaporation in this area has a paramount importance because of its aridity hot climate under the circumstances of saline irrigation water usage. The objective of the present work is to study the influences of irrigation system, water restrictions and soil conditioners onmorphological and chemical characterizes of Moringa, for that,the following measurements are taken Trunk Diameter, Pods Tree Quantity, Seeds Yields (g) per tree, Weight per 1000 seeds (g), oil yields per tree (g), oil Yields per/ Acer (kg), chlorophyll A- B, total chlorophyll, carotenoids, Total carbohydrates, vitamin C,Nitrogen, Calcium, Fe and zinc content of Moringaoleifera plants in addition to Water use efficiency, cost analysis, energy analysis in two studied seasons, (2017-2018/2018-2019). Results show that the most positive influence of irrigation is buried irrigation, drip irrigation and mini-sprinkler respectively, due to the saved water from losses by evaporation under drought conditions. And the most positive influence of water restrictions treatments is 100, 80 and 60% respectively, but the in many measurements the differences between both of 100 and 80% of applied water is not significant, so its more economical to approve 80% of applied water under buried drip irrigation, which means about 20% of applied water can be save.
