Effects of nitrogen applied on wheat straw on winter wheat (Triticum aestivum L.) yields in western Oregon

Creator:: Caputo, John Anthony
Abstract:: Nitrogen deficiency during the winter where winter wheat (Triticum aestivum L.) follows wheat and large amounts of straw have been plowed down has been a factor limiting yield in the Willamette Valley of western Oregon. Field experiments were established to determine if an application of N on the stubble or...

Potash fertilizer effects on yield, hollow heart, and nutrient levels in potato tubers and petioles

Creator:: McBride, Robin L.
Abstract:: Potash rate and source effects on tuber yield and quality (hollow heart, size, and processing quality), and nutrient (K, Ca, Mg, and C1) concentrations in petioles and tubers were evaluated in three experiments, two in the Columbia Basin in Oregon (McDevitt and Levy) and one in Central Oregon (Powell Butte)....

Biological assessment of soils for potential development of take-all root rot

Creator:: McGeehan, Steven L.
Abstract:: Take-all root rot (Gaeumannomvces araminis var.tritici) is a major disease of wheat (Triticum aestivum) in western Oregon. Control of take-all is dependent on management practices such as crop rotation and soil fertility-plant nutrition relationships. The objective of this study was to develop a bioassay that could measure the influences of...

N fertilizer effects on soil solution Mn and Mn response of barley and oats

Creator:: Petrie, S. E.
Abstract:: A series of field experiments was established in 1978, 1979, and 1980 on Lower Klamath Lake where Mn deficiency of oats had been observed in previous years. The pH of the soils ranged from 7.6 to 8.3 and the organic matter content was between 17 and 19%. The objectives of...
