The present work was done with the objective of verifying the effect of nitrogen (N) and phosphorus (P) levels on the development of five progenies of guaranazeiro (Paullinia cupana var. sorbilis (Mart.) Ducke) under nursery conditions. The experiment was carried out in an experimental area of EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária -Porto Velho, RO. Brazil). The experimental design consisted of a completely randomized design with three replications and nine treatments. The results obtained allowed for the following conclusions: a) N1P2 treatment showed better results among those studied; b) Progenies 16 and 13 showed greater potential for development when compared with the others; progeny 29 was second best.
