Abstract: Survival of seedlings in arid and semi arid zones plantation is strongly affected by water availability and soil type. Many tree species are able to adapt themselves in response to soil moisture content. Three soil types, sand, clay and mixture soil (according to the main classification of soil in Sudan) with different irrigation pattern (2, 4and 7 days intervals) were used for propagation of Jatropha Curcas for three months. The experiment was conducted at the nursery and was laid out in a randomized complete design with three replications and the growth characteristics were measured on monthly bases The aim of this study was to evaluate the effect of irrigation pattern and soil types in seedlings growth characteristics of Jatropha Curcas. Seeds used in the experiment were collected from South Kordofan. The results obtained supported earlier findings by some workers. Shoot length showed no significant different over all treatment. The control (normal nursery practices) was the best for all seedling characteristics measurements. These. results may suggest that for successfully a forestation programs, low nursery cost in raising Jatropha seedling recommended to irrigation that practices in the nursery, Since there are no significant differences of juvenile growth performances between the three soil type recommended that caution shouldnt done when Jatrohpa plant
