Farm yields of soybeans have been stagnant over the past two decades in Ontario. With higher commodity prices soybean growers are seeking solutions to overcome the limitations on soybean yields. Current agronomic recommendations in Ontario are based on research with relatively narrow objectives that focus on simple effects of a few factors at a time. Management needs to consider additive and synergistic effects on yield and profitability. This project will study possible additive effects of inputs on different varieties as well as the effects of later maturing bean varieties. A “kitchen sink” approach was applied at the field scale level to assess the impacts of multiple inputs on soybean yields. This treatment package was also broken down into its individual components and applied on 8 different varieties on small plots at the University of Guelph.
