• Response of Dry Onions to Varying Levels of Soil Moisture

      Pew, W. D. (College of Agriculture, University of Arizona (Tucson, AZ), 1965-08)
      Onions respond favorably to increasing levels of soil moisture as measured by increase in bulb size and total yields. Maintaining a soil moisture level of 18-20 centibars of tension (nearly field-holding capacity) produces the greatest yields of bulbs. However, dry onions so produced are somewhat softer in texture, tended toward thick -neck growth, matured slower, and are more difficult to cure adequately in the normal length of time. Onions grown on lesser amounts of water tend to have the reverse characteristics. Costs of production are similarly increased under high soil moisture levels because of the need for replacing nitrogen leached out of the root zone. Also, the costs of the water and its application must be increased. Therefore, the economics involved would be a required consideration.

    • Verticillium Wilt of Potato

      Stone, William J. H. (College of Agriculture, University of Arizona (Tucson, AZ), 1965-08)
      Isolates of Verticillium Albo-atrum were obtained from potato and from cotton. Investigations are in process to ascertain the relationship between cotton Verticillium wilt and potato Verticillium wilt and to determine the significance of the disease to Arizona potato production.
    • Yuma Sweet Corn Variety Trials

      Oebker, N. F.; Grounds, R. E. (College of Agriculture, University of Arizona (Tucson, AZ), 1965-08)
      Eighteen sweet corn hybrids were compared in the Yuma Valley in the spring of 1961. Golden Cross Bantam, especially the 51-T strain, gave the best overall performance.
