Abstract
On the Horticultural Station of the Debrecen University, Pallag, two year old apple plantations of two varieties (‘Pinova’, ‘Golden Reinders’) have been studied, in autumn 2011. The growth of the cross section area of the trunk and the central axis were measured and compared to evaluate the effect of two alternative growing technologies: integrated and/or ecological. ‘Pinova’ proved to grow more intensely than ‘Golden Reinders’ independently from the growing technology. The effect of the technology, however, was expressed in ‘Pinova’, where the integrated technology produced more vigorous growth than the ecological one. The effect of varieties on growing intensity was more distinct than the effect of growing technologies. Under the ecological growing system, the difference between the varieties studied is more accentuated regarding growing intensity. By that reason, in ecological growing plantations of varieties with moderate vigour ought to be stimulated by all possible techniques (as pruning, nutrition etc.).
