Seeds were sown in three orientations (Radicle downwards, radicle upwards and flat position) at four different depths (1, 2, 3 and 4 centimeters) to improve the germination on Jatropha curcas. The results revealed that sowing seed at 2 centimeter depth with radical downwards position enhanced the production of normal seedling and the germination percentage (85%). Compare to radicle downward and flat position of seed at different depth of sowing, speed of emergence and abnormal seedling existence were lower and higher respectively in radicle upward position of seeds with 4 centimeter depth
