In addition, sustained deficit irrigation
that consists of a progressive, uncontrolled water deficit has
also been proposed, with significant water saving (Moriana et al.,
2003; Iniesta et al., 2009; Martín-Vertedor et al., 2011). The above
cited irrigation studies were performed in very different conditions
from arid (Israel) and semi-arid (Spain or USA)to highly rainy zones
(Italy). So, although their conclusions are different and even contradictory,
this is, in fact, a local adaptation of the traditional olive
irrigation scheduling, with a delay in irrigation when conditions
of low water stress during flowering are presented (
