Exponential Nitrogen Fertilization of Luehea divaricata Mart. Seedlings

Abstract

Nutritional balance interferes positively in obtaining high-quality seedlings of wood species. This study aimed to evaluate nitrogen fertilization during the production of L. divaricata seedlings. The experiment was conducted in a shade house located at 24°33’S and 54°04’W, in a randomized block design formed by two forms of fertilization plus a control applied during three months, totaling nine applications, with seven replicates of five seedlings each. Both exponential and conventional fertilization regimes supported the hypothesis of growth induction of L. divaricata seedlings in relation to the control during the growth phase, with exponential fertilization as a valid option to reduce initial nutrient loss by leaching.
