Resumo(s)
With the aim of evaluating production, qualitative and economic aspects of four training systems during 2010, at Peral, Cadaval, 4-yr-old ‗Rocha‘ pear trees (Pyrus communis L.) grafted on Sydo and trained as vertical axis (1.0 x 4.0 m), open tatura trellis (0.8 x 4 m), palmette (1.2 x 4.0 m) and solaxe (1.0 x 4.0 m) were monitored. The highest canopy volume and the lower pruning weight were recorded in the tatura system. No significant differences were observed among systems concerning flower bloom and fruit setting. Production in 2010 was 54.0, 53.7, 54.9 e 38.2 tones.ha-1 for tatura, vertical axis, solaxe and palmette, respectively. The vertical axis was the system with the highest percentage (81.2%) of fruits with diameter > 70 mm and 60-70 mm. Considering cumulative yields and installation and production cost, from the plantation to the 4th year, the net return was -698 €.ha-1, -4501 €.ha-1, -6749 €.ha-1 and -476 €.ha-1 for the vertical axis, tatura, plamette and solaxe, respectively.
