These plant varieties were:
• Parsonii juniper (Juniperus chinensis)
• India Hawthorn (Rhapheolepis indicia)
• Japanese privet (Ligustrum japonicum)
Three general plant size groups (small,medium, large) of
each of the three plant species and two container sizes
(16 cm and 27 cm diameter) were used.
Depending on the plant species, plant size, and container
size, CF was measured at four container spacings ranging
from canopies placed close together to canopies placed
as far apart as 22.9 cms. (See Table Two).
CF was measured using the same methods explained
in Test One with plant height and width determined for
each test plant.
Twelve border plants were placed around the seven test
plants in the same spacing arrangement as the test plants
to maintain the same canopy interaction effects for all
test plants (See Figure One).
The effect of spacing was evaluated with analysis of
Figure One. Arrangement of test plants used to measure
the effect of plant size, container size, and container
spacing on the capture of sprinkler irrigation . ( Seven
test plants surrounded by 12 border (B) plants.)
