Macroelements and Microelements in the Soil and Their Relationship with the Content of Steviol Glucosides in Stevia rebaudiana Bert from Five Regions of Colombia

This study was conducted to determine the effect of edaphic environmental conditions in concentration principal steviol glycosides and Stevia rebaudiana Bert yield, utilizing leaves from five Colombian regions. The structure experiment a randomized complete block design with two treatments 5 × 2 factorial arrangement (5 locations radiation levels). In each experimental unit (UE), healthy plants similar physiological growth age were selected for extraction total (GT), stevioside (Stv), rebaudioside A (Rb-A),and leaf yield. Results analyzed SAS statistical package (version 9.1). Concentrations showed positive increase nitrogen (N), phosphorus (P), magnesium (Mg), copper (Cu). Therefore, they are important available phase soil obtain an these glycosides. Meanwhile, boron (B) presented negative correlation under conditions. For production stevioside, N, Mg, manganese (Mn) had correlation, calcium (Ca) sodium (Na) correlation. Similarly, yields by locality, it found that Ca, B have production, while Mn, iron (Fe) negatively correlate biomass gain.The cultivation stevia can be established different conditions, precipitation solar Colombia. is necessary advance fertilization plans nutrients, considering response metabolites their application.
