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...
