The Republic of Tajikistan is a country with a considerable fruit production potential. One of the factors most frequently implicated as limiting agricultural development, not only in the Republic of Tajikistan but also in other Central Asian countries, is the insufficient development of quality management systems in primary production, which causes difficulties in product exports. Development of a model based on soil properties which would enable evaluation of possibilities of grape production is an important element of supporting a decision-making process in the conditions of quality management systems in primary production. The aim of the study was to evaluate chemical composition of grapes and vine leaves, and the the content of assimilable forms of elements in soil. In 2018, soil samples as well as vine leaf and berry samples were collected in the Republic of Tajikistan, in the area of Dushanbe and Khujand. In the selected plant and soil samples, the content of Al, As, B, Ba, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Sr and Zn was determined. The elements were determined by inductively coupled plasma atomic emission spectroscopy. The results reveal a relatively low potassium, phosphorus and magnesium content in plants and a high content of Cu, Fe, Ni, Pb, Cr, and Al in the grapes under analysis. In no case did the content of potentially toxic elements exceed critical values for products intended for consumption (FAO/WHO 2011). Determination of assimilable forms of elements in soil extracted by means of acetic acid is a useful method of evaluating their abundance in soil under analysis. For most of the elements being tested, statistically significant correlation factors were reported between the content of elements in vine leaves and berries. As regards Sr, Cu, Na, Cd, Zn, As, Al, B, Ba and Pb, a statistically significant relationship was found between their content in leaves and berries.
