Abstract

The experiment was carried out in years 2014-2016 in Żyznów in Poland (49.83°N, 21.85°E). It was realized on the basis of a randomized sub-blocks method in the dependent system (split-plot) in three repeats. Factor of the first type were cultivation technologies: a) traditional technology – as a control object, b) technology using PE- sheeting, c) PP-agrotextile, as a cover. Factor of the second type were three species of sweet potato. Growing sweet potato under cover contributed to the increase in the total yield and commercial tubers, compared with traditional technology; wherein a greater effect as the total yield increases observed in the case of polyethylene, and in the case of commercial crop in cultivation under PP-agrotextile. Field production of sweet potato in Poland’s climate and soil conditions enables the introduction into our daily diet of a new alternative vegetable with high nutritional value and high total and marketable yield. The cultivation of this type of vegetable can potentially influence future horticultural production and provide resources for the processing and pharmaceutical industries.
