A forestation programs in arid regions are one of the main solutions of desertification, but high costs of seedlings plantation is a hindrance. Direct-seeding is a low-cost method and can be an alternative. This research consists of two experiments to exploit the potential of multipurpose and drought-resistance plant of Zizyphus spina- christi for direct-seeding. The first experiment was to hasten germination and it had five treatments which are: soaking seeds for one week, two weeks, three weeks and four weeks and the fifth was the control. All the treatments were significantly different and the three weeks and the four weeks treatments had the best germination rate of (85% and 79%) respectively within two weeks of planting. In the field, and during the rainy season of high mountain region of Yemen, a direct-seeding experiment took place after seeds exposed to several pretreatments. The best germination percentage was found in boiling water treatment for 5 minutes which gave (80%), followed by boiling water treatments for 15 minutes and soaking seeds for three weeks (76% and 68%) respectively. While stratification in cold temperature for three weeks gave (54%) with no significant difference from the control treatment which gave 52%.
