Abstract


In recent decades, the increased interest in natural sweeteners has prompted manufacturers to develop mechanized technologies for the production of dry mass for stevioside for the food and pharmaceutical industry. The yield of dried leaves obtained from one plant affects all the elements of the technology. The results of a number of studies have shown that leaf fertilization is an appropriate method for stimulating the biological potential of plants and for the widespread farming practice, it is particularly important to establish the effect of different bio-fertilizers in a specific soil climate. The purpose of this study is to determine the effectiveness of various bio fertilizers on the productivity of Stevia leaves because of constantly growing organic farming areas. The results of the study found that the influence of the used foliar fertilizers influences the biological activity of the plants, leading to an increase in Stevia's vegetative mass and is a prerequisite for higher yields. The highest values of the studied parameters are the organic liquid fertilizer Ecosyst-Arbanasi, followed by Gropaid NPA.


Keywords
