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).
