          Abstract

          ABSTRACT High prices and the scarcity of hardwoods require the use of alternative wood sources, such as the Guapuruvu (Schizolobium parahybae), an arboreal species native to the Atlantic Forest, which has fast growth and high market potential. However, there is no information on its cultivation in the Brazilian Cerrado. Thus, this study aimed to analyze the contribution of mineral fertilization and liming in a Cerrado soil on the initial growth of Schizolobium parahybae. The experiment was set in a randomized block design, with 4 treatments (Cerrado soil; soil + liming; soil + fertilizer; and soil + fertilizer + liming) and 15 replicates. The following variables were analyzed: plant height, stem diameter, number of leaves, total, shoot, leaf, root and stem dry matter, and root/shoot ratio. The obtained data were subjected to the analysis of variance, Tukey test and regression analysis. During the initial growth, Schizolobium parahybae can be cultivated in a Brazilian Cerrado soil only under mineral fertilization, with no need for soil liming.

          RESUMO Os elevados preços e a escassez de madeiras nobres tornam necessário o uso de fontes alternativas de madeira, como guapuruvu (Schizolobium parahybae), espécie arbórea nativa da Mata Atlântica a qual apresenta rápido crescimento e alto potencial mercadológico; todavia, não há informações sobre seu cultivo no cerrado do Brasil; objetivou-se, neste sentido, analisar a contribuição da adubação mineral e da calagem no solo do cerrado sobre o crescimento inicial de Schizolobium parahybae. O delineamento foi em blocos casualizados, com 4 tratamentos (solo do cerrado; solo + calagem; solo + adubo; solo + adubo + calagem) e 15 repetições. As variáveis analisadas foram: altura de planta, diâmetro do caule, número de folhas, massas secas totais da parte aérea, das folhas, da raiz e do caule e relação raiz/parte aérea. Os dados obtidos foram submetidos à análise de variância, ao teste de Tukey e à análise de regressão. Observou-se, durante o crescimento inicial, que o Schizolobium parahybae pode ser cultivado em solo do cerrado brasileiro apenas com adubação mineral sem a necessidade de calagem do solo.
