(Anova)

conducted separately for each species,

container size, and plant size group.

For each plant species and container size, linear regression

was used to relate plant height, plant width, and plant size

index to CF measured at the widest spacing.

Test Three: Sprinkler head type Wobbler versus impact

In order to gauge the most effective method of sprinkler

irrigation, Wobbler sprinklers were compared with impact

sprinklers for their effect on the irrigation water capture,

Irrigation uniformity and application rate were measured

for both sprinkler types by collecting irrigation water in
