Effect of irrigation water qualities on Leucaena leucocephala germination and early growth stage
The evaluation of nonconventional water resources on seed germination
and seedling growth performance at early growth stages is still in
progress, especially on multipurpose forest trees. This study was
designed to test the effect of four water qualities [treated
wastewater, industrial, gray and distilled water (control)] on
germination and early seedling vigor of Leucaena leucocephala . The
results showed that germination was not significantly affected by
different water qualities. Seed germination reached a maximum after 17,
14, 14 and 21 days under gray, industrial, treated wastewater and
control irrigation, respectively. The highest mean of shoot length was
scored under gray water irrigation. Likewise, the highest mean of root
length was scored under control, which was not significant from gray
water. The means of shoot fresh and dry weight were the highest under
treated wastewater. The means of root fresh weight and root dry weight
were not significantly different under water treatments. The shoot/root
ratios under all water qualities treatments were significantly higher
than the control. Growth performance was in progress with no mortality
during 21 days of growth. The best nonconventional water quality
alternatives based on cleanness, nutrients and toxicity are the gray,
treated wastewater and industrial water, respectively
