This book was released on 1963 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to make a preliminary investigation of the productivity of some of the soils within the Willamette catena under different systems of soil management. The study was carried out at four experimental sites near Corvallis, Oregon, during the 1962 growing season. The soil at each site was representative of a different soil series. The soil series were Willamette, Woodburn, Amity, and Dayton which are well-drained, moderately well drained, imperfectly drained, and poorly drained, respectively. Productivity was measured in terms of shelled corn yield. The eight treatments (systems of soil managements) were different combinations of irrigation, plant population, and nitrogen fertilization practices. The irrigation treatments were irrigated and non-irrigated. The Ievels of plant population were 9000, 14000, 18000, and 22000 plants per acre. The rates of nitrogen fertilization were 60 and 180 pounds of N per acre. A second objective of this study was to measure the response of field corn to each of the three soil management practices. Data pertaining to the effects of the three practices on shelling percentage and ear moisture at harvest, as well as grain yield, were collected. There were significant yield responses to irrigation when accompanied by higher levels of plant population at all sites. Generally, yield responses to higher levels of plant population and the higher rate of nitrogen fertilization were measured on the irrigated plots, but not on the non-irrigated plots. The shelling percentage on the irrigated plots was higher than that on the non-irrigated plots only at the Amity and Dayton sites. Apparently, plant population and nitrogen had no effect on shelling percentage. The amount of moisture in the ears at harvest was apparently not affected by irrigation, plant population, and nitrogen fertilization practices. In general, the productivities of the soils at the Willamette, Woodburn, and Amity sites were similar and significantly greater than at the Dayton site under all systems of soil management.

Book excerpt: Experiments involving varying plant populations and nitrogen levels were conducted at the Main Experiment Station during the years 1949 to 1957. From 1957 through 1959 fertilizer experiments using N, P, and K were conducted at various locations at the Main and Branch Experiment Stations. Conclusions drawn from these experiments are: 1. The optimum number of corn plants, when plant food is adequate, appears to lie between 12,000 and 16,000 plants per acre. 2. The optimum amount of nitrogen (with all other needed elements supplied in ample amounts) will depend upon the amount and rate of mineralization of soil organic matter. In these experiments 150 to 180 pounds gave the highest yields, but something less than this would probably give more return per dollar spent for nitrogen. 3. Good response to nitrogen was generally obtained on the bottomland and terrace soils of the state. When substantial response was obtained, the efficiency was near on bushel increase for each two pounds of nitrogen. 4. Limited, but statistically significant, response to phosphorus was obtained on Loring silt loam, a typical terrace soil. No response was obtained on Dundee, Tunica, or Portland, typical bottomland soils. 5. No significant yield response was obtained from potassium in any of the tests, although there was a slight tendency toward such a response in a few cases. 6. A combination of nitrogen, phosphorus, and potassium did not increase yields over nitrogen alone on the bottomland soils nor did it increase yields over the combination of nitrogen and phosphorus on the terrace soils. 7. Ear weight and number of ears per stalk decreased with increasing plant population. However, at a constant population ear weight and number of ears per stalk increased with increasing nitrogen application. Ear number was affected to a greater extent than ear weight. 8. Nitrogen was the only plant food elements that significantly affected ear weight and number of ears per stalk. 9. Nitrogen increased lodging while phosphorus and potassium had little or no effect on lodging.
