Good management practices are essential if optimum fertilizer responses are to be realized. These practices include adequate irrigation, use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Because of the influence of soil type, climatic conditions,...

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...
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...
