Ontario is a world-class producer of seed corn, due to the region’s exceptional combination of climate, soils, production expertise and infrastructure. As with other production areas, the competitive nature of the North American seed corn industry has had a significant impact in Ontario and the industry has gone through significant changes in recent years and unfortunately challenges to the industry will remain. However, problems in seed corn production in the United States during 2011 growing season highlights the importance of maintaining a healthy Ontario seed corn industry. Production of seed in the province enhances or increases the regional diversity of the seed corn production system in North America which is critical to meeting corn seed supply requirements in the future. Environmental concerns with nutrient and pest management and competition for land base with other rotational crops are part of these production challenges.
