Abstract

Water use (WU), water use efficiency (WUE), growth,
productivity of Picual and Arbequina olive cultivars were studied
under two irrigation systems (flood and drip) during 2007and
2008 seasons.
Results showed that, seasonal water use of olive trees grown
under flood and drip irrigation was 704.04 and 446.95
mm/feddan/year, respectively (average of the two seasons). Olive
trees subjected to drip irrigation produced the highest yield/tree
16.6 Kg (average of the two seasons). Yield decreased by about
23.67% when trees were exposed to flood irrigation system. Yield
efficiency and water use efficiency of olive tress had the same
trend. The maximum values, in this respect, were obtained by olive
trees grown under drip irrigation followed in a descending order by
flood irrigation, respectively.
On the contrary, olive trees grown under flood irrigation
system gave higher values of vegetative growth parameters and
percent of fruit dry weight. However, it gave less fruit yield as well
as percent of oil in flesh dry weight. Olive trees grown under drip < br />irrigation system gave the highest value of oil% per flesh dry
weight (43.99% average of the two seasons). Meanwhile, this
percent decreased by about 8.54% when trees were irrigated by
flood irrigation.
Moreover, from the obtained data, it is clear that Picual cv. had
that bigger tree canopy, fruit yield, fruit weight, fruit dry matter
and fruit oil content more than Arbequina cv.
Consequently, it could be recommended cultivate trees of
Picual cv. in the new reclaimed land as it was more suitable than
Arbequina cv.
