Sweet potato should be cultivated grown in hillock system as it is typical for carrot cultivation. Recommended distance between rows (hillocks) is 1.20 m; narrow distance (minimally 1.0 m) could be used in small gardens. Prepared or bought seedlings should be planted in row into the distance of 0.30 m. Mulching by black non-woven textile, PE foil or organic materials (straw etc.) is recommended for cultivation, mainly and necessarily in conditions of Slovak republic or middle European countries.
