PLANT GROWTH AND YIELD RESPONSE OF THE OLIVE TREE CV KALAMON, TO DIFFERENT LEVELS OF SOIL WATER POTENTIAL AND METHODS OF IRRIGATION

Olive trees 7 year old cv Kalamon irrigated for 5 years at soil water potential levels higher than -0.02 and -1.5 MPa were compared with non irrigated trees.
Irrigation water was applied by two drip laterals per row or a microtube-fed basin per tree for -0.02 MPa and one drip lateral per row or a microtube-fed basin per tree for -1.5 MPa.

Trees height, canopy diameter and trunk perímeter were significantly smaller in all years in the non irrigated than in the irrigated trees which showed no significant differences.
Tree height, canopy diameter and trunk perimeter were increased in all treatments during the irrigation season but did not show significant differences between irrigated and non irrigated trees.

Fruit drop, from fruit-set to harvesting, did not differ significantly between treatments although was generally higher in the non irrigated than in the irrigated trees.

Oil content of the fruits was significantly lower in non irrigated than in the irrigated trees but only in the high yield years.
