The trial design was based on the two factors:
Factor A: taking in three irrigation regime treatments,
• T1-fully irrigated,
• 72-VXVWDinHd dHÀFiW iUUiJDWHd
• T3-control, non irrigated.
Factor B with three cardinal points:
• South,
• North
• East-West
The tree canopy was viewed by thermal images taken
from a distance of 1.0-1.5 m and a height of 1.5 m
perpendicular to the area being imaged towards the
middle of the tree canopy.
The three irrigation regime treatment plots were situated
at least 50 m apart from one another. Canopy width and

three measurement occasions are depicted in Figure One.
The instant values of SMC have been encompassed
between WP line and FC line, i.e. T1 mainly near MAD
line, whereas T2 and T3 between MAD line and WP line,
slowly decreasing with depth.
Fruit trees have been observed to react to water stress
differently at such SMC values.
The large porous space between FC and TC is normally
