Potatoes were harvested 60 and 75 days after planting. The result of employing the non-woven polypropylene covering contributed to increase in the dry matter content in tubers on an average by 1.17 percent in comparison with the cultivation without the plant covering, but did not have effect on the starch, protein and vitamin C content in tubers. The content of examined components in potato tubers in greater degree depended on the harvest date and meteorogical conditions in the vegetation period of potato. The retarding of harvested date contributed to increase concentration on the nutrient components in tubers. Independently of employed the cultivation technology the contents of dry matter, starch and vitamin C in tubers of both cultivars showed no significant difference, however, higher protein on average by 0.14 percent contents in tubers of Aster cultivar
