Abstract

Studies of the influence of microelement fertilizers to the quality of potatoes of different varieties was carried out in 2014, in Ukmerge district. Influence of microelement fertilizers and genotype to potato yield and dry matter content was explored during the study. There were two different fertilizations (N102P48K132S198Mg18; N102P48K132S200Mg19Fe0,15Mn0,07Zn0,014Cu0,0056B0,17Mo0,006) and three potato varieties (Sylvana, Jelly, Fakse) in the study. It was obtained, that Fakse potato variety yield was 5,45 t ha-1 higher when microelement fertilizers were used, but Sylvana and Jelly potato yield was about 13 % lower when microelement fertilizers were used. Dry matter content was significantly higher when microelement fertilizers were used on Sylvana and Jelly potatoes, but lower (1.476%) when used on Fakse potatoes. The study revealed that potato yield and quality are determined by variety
