UTILITY OF NUTRITION WITH NITROGEN, PHOSPHORUS AND POTASSIUM DISSOLUTIONS IN THE APPEARANCE OF ORTOTROPIC SPROUTS

Abstract

Introduction: reforestation is a strategy to face natural changes and those caused by human activity that endanger various forest species. It also allows addressing the timber needs inherent in current economic and social development; so it is necessary to potentiate this activity and achieve higher levels of effectiveness in it. Objective: To evaluate the response of the mother plants with respect to nutrition with doses of nitrogen, phosphorus and potassium solutions in the appearance of orthotropic outbreaks. Methodology: an experimental, descriptive and longitudinal study in which young plants of neotropic Juglans were subjected to clonal forestry techniques by using different nutritional solutions to identify their effect on the appearance of outbreaks. The solutions were composed of nitrogen, phosphorus and potassium. Pearson's chi-square, continuity correlation, likelihood ratio and linear association were used to identify the statistical significance of changes in the appearance of outbreaks according to the type of solution used. Results: there was a greater appearance of sprouts in plants that were treated with solutions of potassium, nitrogen and phosphorus. There were significant differences around the appearance of outbreaks according to the concentrations of the macronutrients of the solutions. Conclusions: a highly significant relationship was found between the appearance of orthotropic outbreaks and the dose of potassium, nitrogen and phosphorus solutions, the importance of potassium in plant growth is confirmed.
