25 Nov 2008
Project Description
This project began with a uniformity trial conducted in 2008 at Elora, Ontario. Long-term and short-term N rate treatments commence in 2009.
Objectives
- Assess short-term and long-term effects of N in maize production on productivity, environmental impact, profitability, and cropping system sustainability.
- Support the validation of crop models, such as Hybrid Maize, for simulating yield potential, seasonal growth and yield, and fertilizer N management requirements.
