CONCLUSIONS Bubbler system show poor performance with
55% to 65% emission uniformity. As a result of low uniformity trees at 1st quarter
were over irrigated while trees at last quarter were under irrigated.
Drip lines have shown uniform distribution of an average emission uniformity of 97%.
Design of drip irrigation system for large trees like date palms proves to be more efficient.
