The effect of major nutrients on Jatropha Curcas yield and oil

There is lack of science based production recommendations for Jatropha in Zambia. In particular fertilizer supplementation regime and this may be contributing to observed low yield. Jatropha growers in Zambia have continued experiencing poor yields and oil of Jatropha, hence if it is to remain the best alternative for fuel there is need to improve the performance of it using mineral fertilizers. In addition, Jatropha growers experience poor yields because there has been inadequate documentation on the nutrients Nitrogen, Phosphorus, potassium and Sulphur ( NPK and S ) that increase the oil production of the plant. This paper shows the positive effects of using appropriate nutrient levels of fertilizers for the efficient production of Jatropha oil.
