The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...
Yield, occurrence of root canker (B deficiency), and leaf nutrient concentrations of the Morse strain of ‘Detroit Dark Red’ table beet (Beta vulgaris L.) as influenced by combinations of lime and N, B, and P fertilizers were evaluated in three studies. Greatest total yields and most favorable distribution of root...
Bush beans (Phaseolus vulgaris L.), carrots (Daucus carota L.), and lettuce (Lactuca sativa L.) were grown for 3 years on soils amended with S or lime and N fertilizer. Yields of all crops increased with lime application but response to N varied among crops and years. Lettuce head weight tended...
Corn (Zea mays L., 'Illinois WF 9x38-11') and potato (Solanum tuberosum L., 'Russet Burbank') were grown in dithizone purified nutrient solutions to contrast relationships between dry matter yield, tissue phosphorus (P) concentration, and tissue zinc (Zn) concentration as they influence the development of Zn deficiency and P toxicity. Treatments consisted...

Irrigated pastures in western Oregon usually consist of Ladino or New Zealand white clover and Alta fescue, perennial ryegrass, orchardgrass, or meadow foxtail. These recommendations are intended for improved pastures with a good stand of clover and improved perennial grasses. Fertilizer seldom pays on weeds or weedy grasses.
Improved nonirrigated pastures consist of subterranean clover) New Zealand white clover or lotus major (big trefoil). These legumes are generally planted with perennial or H-1 ryegrass, alta fescue, orchardgrass, or meadow foxtail.
Fertilizing weeds and weedy grasses (bent, velvet, and June grass) seldom pays.
Experiments at the North Willamette Experiment Station have evaluated response of vegetables to lime and other fertilizers since 1970. The soils are moderately acid (pH 5.4 to 5.6), high in P, and better drained than most soils used for vegetable crop production in western Oregon. Typical soil acidity problems such...

Good management practices are essential if optimum fertilizer responses are to be realized.
These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seed bed preparation, proper seeding methods, and timely harvest.

Data from fertilizer experiments with potatoes in the Willamette Valley from 1961 through 1971 show that responses have been measured from nitrogen, phosphorus, potassium, magnesium, and lime. Responses from these nutrients have been related to soil and/or plant analysis values. In recent years most of the potato production has moved...
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...
