Evaluación del efecto del potasio y magnesio en el cultivo de (Saccharum officinarum l) en soca variedad poj negra en el Dorado-Orellana

Abstract

In Orellana, sugarcane performance (Saccharum officinarum L) is low, due to several factors, including poor crop management and information lack on fertilization, mainly on potassium and magnesium importance in the plant, which limits maximum performance and good quality sugarcane juice, Therefore, general objective this research was to evaluate the application effect of potassium and magnesium in sugarcane cultivation (Saccharum officinarum L) in soca black POJ variety through of morphological variables analysis, performance and quality to identify production alternatives in El Dorado parish - Orellana. The implemented methodology had a quantitative and qualitative approach, which 3 treatments (low, medium and high dose) potassium and magnesium were applied, using Completely Randomized Block Design (CSBD), obtaining results through statistical analysis using variance analysis (ANOVA), followed by Tukey mean comparison test with 5 percent significance. The results showed that, for morphological variables, treatment with high doses of potassium and magnesium presented greater diameter, length internodes and, in same way, greater crop yield, while in variables of juice quality, treatment high doses of potassium obtained greater juice yield with 6108.33 ml, also obtained a greater quantity of soluble solids 18.83 percent. In this context, it was concluded to higher the dose of potassium and magnesium improved the morphological characteristics, increasing performance and improving juice quality.
