Abstract:

In 2011 and 2012, a field trial was conducted in the experimental field of the Biotechnical Faculty, University of Ljubljana, Slovenia. The trial involved four potato cultivars (i.e. Faluka, Manitou, Madeleine and Stirling). Its aim was to determine statistically significant differences in the requirements for the growth with regard to the space in the ridge with different potato cultivars. For that purpose, the following parameters were defined and studied: area of the form surrounding the tubers (ellipse and cluster), cross-sectional area of the ridge, vertical and horizontal tuber span in the ridge, lengths of semi-axes [a] and [b] of the ellipse, minimum distance of tubers and ellipse from the outer ridge side. The trial design was a randomised block with five repetitions. Faluka had the largest tuber cluster area, cross-sectional area of the ridge and vertical tuber span. It also had the longest semiaxis [b] of the ellipse and resulted in the highest yield. There were no statistically significant differences in the horizontal tuber span and the length of semi-axis [a] of the ellipse. In 2011, the cultivation of Faluka resulted in the smallest distance of tubers and ellipse from the outer ridge side when compared to the other cultivars under consideration. It was determined that different cultivars have different requirements for the growth with regard to the space in the potato ridge. Further research should include additional trials with different potato cultivars on different soil types and the study of addition parameters (mass and equivalent diameter of a tuber).
