Jatropha curcas is a multipurpose species, with uncountable attributes and remarkable potential. It is a plant from tropical origin, of the Euphorbiaceae family, which can grow in zones of high as well as low annual rainfall. It is highly resistant to drought and can be cultivated in marginal areas, for which it is exceptional for the recovery of degraded lands, without competing with crop production for human and animal health. In addition, it is used as living fences and hedges, medicinal and insecticide properties are ascribed to it, and it can even be used as commercial crop. This is a fast growing species and seed production can begin even in the first year of establishment, which depends on many factors, such as rainfall and the form of propagation that is used (by seeds or cuttings). Its establishment, management and productivity under different edaphoclimatic conditions is not well documented yet, mainly concerning its nutrient or fertilizer requirements and, in the case of Cuba, most of the studies related to its agrotechnical practices and production are just beginning. This plant contributes many beneficial products, especially from its seeds, from which oil can be extracted, with a similar quality to that of the oil palm. This oil can replace kerosene, petroleum and firewood/coal with relative success, for which its use is promoted internationally to satisfy the demands of rural zones regarding illumination, cooking and engine power. Other very important uses are biofuel production from the oil, soap manufacturing and glycerin extraction for industrial purposes. Its cultivation and expansion could provide new employment sources, as well as improve the environment and the life level and quality of the rural population, for which the real potential of this plant must be carefully studied, from the point of view of its agronomy and management, as well as its use and commercialization in the future.
