This study
was conducted in Turkey in 1997 and 1999 to investigate the effects of
different irrigation methods and regimes on the vegetative growth of
"Starking Delicious" apple trees under Thrace conditions. Drip and
surface (ponding) irrigation methods were the basic treatments while the
allowable depletion levels of soil moisture (40% and 70% of available
water holding capacity) in 120 cm soil depth were sub treatments.
Seasonal evapotranspiration and total amount of irrigation water in
drip irrigation plots were lower than those of surface irrigation plots
(62.7% and 72.5%, respectively). However, the effect of irrigation
regimes on vegetative growth parameters was nonsignificant. Drip
irrigation gave better results than surface irrigation when irrigation
water requirements, evapotranspiration, and vegetative growth
parameters were evaluated together. In conclusion, it can be suggested
that drip irrigation should be preferred for apple trees under Thrace
conditions and irrigation water should be applied when moisture reaches
40% of the available water holding capacity. |
