Effects of Different Irrigation Methods on Vegetative Growth of Apple Trees Grafted on M9

This study was carried out to determine the effects of different irrigation methods (drip (d1), subsurface drip (d2), surface (y) and under-tree micro sprinkler (m)) on vegetative growth of jersey mac (ç1) and williams pride (ç2) apple cultivars budded on m9 during the years between 2006-2008. experiment site was in research and application farm of agricultural faculty, university of suleyman demirel. applied water amounted %100 of class a pan evaporation measured during five irrigation interval. in the experiment years, applied irrigation water amount and measured crop evapotran spiration values in drip irrigation methods were 67 % less than under-tree micro sprinkler and surface irrigation methods. according to the results, the highest trunk crosssection unit area values were determined in 2006, 2007 and 2008 years with respectively 2.94, 6.23 and 8.96 cm2 in drip irrigation method (d1). in the last year of the experiment, the highest tree height, canopy volume, shoot length, numbers of shoot values were obtained in drip irrigation method (d1) as 212.83 cm, 2.29 cm3, 40.33 cm and 11.73 respectively.
