Abstract: Survival of seedlings in arid and semi-arid zones plantation is strongly affect by localities requirements (soil ,moisture and climate) Many tree species are able to adapt themselves in response to these factors. Seeds from sand, clay and mixture soil (according to the main classification of soil in Sudan) which representing by sinnar, Kordofan and Southern Darfur States used for propagation of khaya Senegalensis for three months. The experiment was conducted at the nursery and was laid out in randomized block design with 8 replicates and the growth characteristics were measured on monthly bases The aim of this study was to evaluate the effect of localities requirements in seedlings growth characteristics of khaya Senegalensis. The results show significant variation in growth and productivity, which found directly correlated to environmental conditions prevailing in each geographical area. It recommended that care should made not to transfer seed from one locality to another because each plant is adapted to its own specific climate condition and a wrong seed transfer may lead to serious losses of plant martial which may fail to grow successfully away from their natural habitats
