  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.).

  The transplant-growing with root balls gets more and more popular and time to time the only method even in high-quality lettuce transplant-growing. To work out the technology of transplant-growing in trays it was needed to define the accurate physical and chemical consistency of applied soils.

  The transplant production in trays could become a good method in field-grown lettuce technologies. The production of transplants of good quality with this technology could be realised only by accurate soil mixtures.

  The matter of transplant-growing substrates could be a low-moor turf. Its qualities could be positively influenced by adding minerals like bentonite in amount of 5 (or 10) V%.

  To ensure enough phosphorus for the demands of transplants we have to add more fertilisers. The best results by lettuce we got by adding 4 kg/m³ superphosphate to the soil mixture.
