The objective of this research was to characterize the nutritional limitations of Jatropha curcas, in addition the effect of the absence of certain nutrients in the growth of the plant. The research was carried in the greenhouse conditions at Agriculture Science Institute of Federal University of Minas Gerais, Brazil. The soil was used dystrophic Yellow Oxisol, colleted in the superficial layer (0-20cm), under cerrado vegetation. The experimental design was totally randomized with 13 treatments and three replications. The treatments were based on the missing element technique (with omission of liming and each one of the macro and micronutrients). The plants without the nutrients P, K and liming showed less growth. The nutrients N, P, K, Ca, Mg e liming affected the shoot of plants. The roots were more affected by absence N, P, Mg and Ca. The results allowed concluding that the macronutrients were more limiting to growth of plant.
