Chemical fertilization, organic fertilization and pirolygneous extract on vegetative development palm phoenix (Phoenix roebelenii)

Abstract

The effect of the use of chemical fertilization, organic fertilization and pirolygneous extract (EPL) was evaluated in the width and number of leaves of seedlings of phoenix palms. The plants were fertilizer with organic castor bean, chemical fertilizer NPK 20-05-20 formula and EPL concentrations of 0,1 and 0,2%. The length of the longest leaf and leaf number were evaluated monyhly for one from the start of the experiment. The data were analyzed by ANOVA and Tukey test at 5% significance level. Treatment organic fertilizer and EPL 0,1% + organic fertilization increased the number of leaves of palm phoenix plants. Mineral fertilizer NPK combined or not with EPL provided no increases in length and number of leaves. The EPL itself did not change the parameters.
