INVESTIGATION OF PRODUCTIVITY OF DIFFERENT POTATO CULTIVARS

Abstract

The objective of the study was to assess the productivity of different potato cultivars. The potatoes of different cultivars were cultivated on a farmer‘s field in Jagėliškiai village, Šakiai district, in 2024. The soil of the experimental plot was light loamy, slightly unsaturated, typical leached soil ((Haplic Luvisol). The subject of the study included potatoes of the following cultivars: ‘Melody’, ‘Aztec Gold’,’Madrid’and ‘Montreal’. The reported indicators include: the average tuber weight per plant, the average numbers of tubers per plant and the average tuber weight.

The highest tuber productivity per plant was recorded of the ‘Melody’ variety, while the lowest was observed for the‘Aztec Gold’ variety. It was determined that the variety had significantly effect on the average tuber weight per plant. Furthermore, the variety also had a substantial influence on the average number of tubers per plant as well as the average tuber weight of a one tuber. A comparison was made between farm-planted cultivar ‘Melody’ potatoes and new potatoes cultivars the ‘Aztec Gold’,’Madrid’and ‘Montreal’ to evaluate which cultivar could potentially replace ‘Melody’ in agricultural practice.
