The present paper has as objective the evaluation of the nutritional aspects, fertilization effect and omission of nutrients in the plants grow of canela sassafras (Ocotea odorifera (Vell.) Rohwer), in a vegetation house for 24 months, consisting of 11 treatments and five repetitions, with seasonal collections, using the springer material. The treatments consisted of control (natural soil), complete fertilization (N, P, K, Ca, Mg, S, Zn and B), fertilization with individual nutrients omission (-N, -P, -K, -Ca, -Mg, -S, -B, -Zn) and organic fertilization (bovine manure). Natural fertility soil and plants of canela sassafras originally from natural  regeneration dispossess in causality statistical  delineation were utilized. The height, diameter length and biomass were evaluated. To the development in height of the canela sassafras, the more limited  nutrient were sulphur and to the diameter  length was the fertilization with macro and micronutrients, but there was no significant difference between the treatments. The roots dry mass reduced when used macro and  micronutrients fertilization, and the dry mass of the  aerial part with the omission of N and P. The organic fertilization demonstrated to be efficient, so much for the increment in height, as for the production of foliar mass. doi: 10.4336/2009.pfb.58.17
