On the basis of multiannual field experiments conducted in central Poland the relation between the air temperature sum (T-SUM) and the length of vegetation period (L-v) of potato crops is described. It is shown that air temperature has significant influence on the duration of vegetation. The exponential equations describing relationship between L-v and T-SUM are formulated for three maturity groups of potato crops: early, medium and late. The data sets of L-v and T-SUM with their descriptive statistics for these potato groups are given as well. (C) 2003 Elsevier B.V. All rights reserved.
