The effect of the potato cultivation method (no covering, covering by nonwoven polypropylene from planting to full emergence, covering by nonwoven polypropylene from planting to the plant height of 15 cm) on the consumption quality of immature tubers of very early potato cultivars (‘Aster’, ‘Koral’, ‘Malwa’, ‘Orlik’) was investigated. The potatoes were harvested 60 days after planting in the second or third 10-day period of June. The forwarding of potato vegetation by nonwoven polypropylene covering caused only a slight increase in the dry matter, starch, and vitamin C content in tubers, in comparison with the no covering cultivation. The consumption quality of the immature tubers of ‘Aster’ and ‘Koral’ cultivars, estimated by the dry matter, starch, protein and vitamin C content, was higher than that of ‘Malwa’ and ‘Orlik’ cultivars. The variability of starch and vitamin C content in potato tubers was higher than that of the dry matter and protein content. The differentiation degree of the starch and protein content in the tubers of the examined potato cultivars was similar to, but the differentiation of the dry matter and vitamin C content in the tubers of ‘Orlik’ cultivar smaller than, that of the tubers of remaining cultivars.
