Notes: The Hermiston and La Grande trials were damaged by a hail storm on June 24, 1999. La Grande trials were also damaged by

cold winter temperatures.

All seed was treated with fungicide and Gaucho insecticide unless otherwise noted.

Seeding rate was 20 seeds per square foot for dryland sites and 30 seeds per square foot for irrigated and Willamette Valley locations.

The Stephens high seeding rate entry was 10 seeds per square foot above these rates. The low seeding rate was 10 seeds per square

foot below these rates.
