1. Vanhie, Michael. Soybean Response to Management of Corn Residue through Removal, Tillage, Stalk Chopping, Planter Type, and Nitrogen Application .

Degree: 2014, University of Guelph

It is suspected that increasing amounts of corn (Zea mays L.) surface residue are resulting in an increasing yield deficit in no-till (NT) relative to conventional till (CT) soybeans (Glycine max Merr.). The objective of this research was to test if soybean yield responds to residue management strategies including removal, tillage timing and intensity, stalk chopping, planting equipment, and nitrogen application, and to determine the mechanisms responsible. Four field trials were conducted in the 2700 – 3000 CHU region of Ontario during 2011 and 2012. Yield was responsive to tillage system, planter type, and nitrogen application but these yield trends were not related to residue cover. NT yield was reduced by 11% relative to CT, but only if residue was chopped and soybeans were seeded with a drill. This suggests the increasing frequency of a NT yield deficit is caused by the increasing prevalence of stalk chopping combine heads, and that it can be alleviated by avoiding stalk chopping operations or seeding with a row planter. Advisors/Committee Members: Deen, William (advisor).

2. Westra, Sabrina Veiga. Non-uniform stands of red clover (Trifolium pratense L.) underseeded to winter wheat (Tritcum aestivum L.): A survey study to identify causes .

Degree: 2015, University of Guelph

Red clover (Trifolium pratense L.) use as an underseeded cover crop to winter wheat (Triticum aestivum L.) has declined in recent years as producers have been experiencing difficulties in maintaining uniform stands. The purpose of this study was to confirm if spatially variable emergence densities, wheat competition, or soil moisture could explain red clover non-uniformity within commercial wheat fields, where agronomic conditions did not vary within locations. A survey study was conducted at multiple locations over two years in Southern Ontario. Red clover non-uniformity was more pronounced in the first year, which had a relatively drier spring than the second year of study. None of the variables measured during in the first year were strongly correlated with final red clover biomass. In the second year, red clover densities measured shortly after emergence and soil moisture were more predictive of final red clover biomass than competition of the overlying wheat stands. Advisors/Committee Members: Deen, William (advisor), Martin, Ralph C (advisor).

Subjects/Keywords: Red clover; Crop rotation; Cover crops
