The pear scab fungus (Venturia pyrina Aderh.) has been in
Oregon for many years. It has become a serious economic problem

A multitude of biotic and physical factors, many of them unique to riparian environments, interacted to form an extremely complex ecosystem along Catherine Creek in the Wallowa Mountains. A total of 258 stands of vegetation representing 60 communities was identified. At least 20 species of mammals and 81 species of...
"Crested wheatgrass, beardless wheatgrass, and big bluegrass were
seeded as overstory grasses. Streambank wheatgrass, canby bluegrass,
bulbous bluegrass, and Ladak alfalfa were seeded as companion species.
Pure and mixed stands were seeded on sagebrush-bunchgrass
range in eastern Oregon to compare yield and competitiveness. The
grasses were planted in 1956, 1957,...
In a series of 30 winter wheat fertilizer experiments conducted in the Willamette Valley between 1963 and 1969, optimum rates of nitrogen fertilization varied from 75 to 150 pounds per acre. Fertilization with N, particularly at the-higher rates, increased the protein content of the grain.
Spring-applied N gave greater yield...
