The culture of the castor bean comes as a promising alternative for the producing of the semi-arid Northeasterner, mainly for to present characteristics as adaptation to the climatic conditions and to present in seeds they nourish chemistries of addition importance for production of Biodiesel, however, they are still scarce studies on techniques handling of this culture, mainly as the manuring This work driven with the objective of evaluating the initial development of the castor bean submitted to different sources and doses of organic matter. The used design was it entirely randomized in factorial outline 2 x 5, with three replications. The treatments were composed by the combination of two sources (manure bovine and manure ovine) and five tenors of organic matter in the composition of the substratum (0, 10, 20, 30 and 40). The appraised growth indexes were: plant height, number of leaves, stem diameter and fitomassa of the aerial part. The castor bean answered the sources and the studied doses significantly, as well as the interaction among these factors. Answer was verified forms quadratic the doses of bovine and lineal manure to the doses of manure ovine. The largest development of the plants was verified with bovine manure, in close tenors of 30%.
