Fertirrigação na produção de mudas de Eucalyptus grandis nos períodos de inverno e verão

Abstract

Studies correlating the splitting of fertigation with the development and quality of tree seedlings in different production systems and periods of the year are fundamental to optimize inputs and minimization of the production cycle. Thus we conducted this study aimed to check the influence of the split of fertigation in the development and quality of Eucalyptus grandis seedlings in winter and summer periods. The fertilization through the irrigation system by capillarity was split on: one, two, three or six times in the week, maintaining the total amount of nutrients applied. We concluded that the most effective fertigation for the development and quality of seedlings of Eucalyptus grandis were six and one times in the week for the period of winter and summer, respectively, demonstrating the need for adequacy of fertigation managements according to the period of year.
