In 2008, Muck Crops Research Station staff conducted and/or cooperated on research projects with researchers from the Departments of Environmental Biology and Plant Agriculture at the University of Guelph; researchers from OMAFRA, Agriculture and Agri-Food Canada, and Cornell University; research departments of the Crop Production Chemical Industry, numerous seed companies and growers. This report consists of two sections; the first contains highlights of research projects which were conducted in 2008 under the supervision of Associate Professor, Dr. Mary Ruth McDonald and other researchers at the University of Guelph. The second section contains highlights of various muck crops cultivar evaluations in 2008 in field and storage trials, under the supervision of the Research Station Manager, Shawn Janse. The results published in this report should be treated as a progress report. Some chemicals used in the trials are not registered for use on the crops they were applied to. Additional trials may be necessary before firm conclusions and recommendations can be made.
