2007 Sunflower Survey: Yield, Plant Populations, and Weed Incidence in North Dakota and Surrounding Regions

This survey conducted by the National Sunflower Association in 2007 provides insights into sunflower yields, plant populations, and weed incidence in North Dakota, as well as neighboring states and Manitoba. The survey covers various factors affecting sunflower production, such as row spacing, tillage practices, yield-limiting factors, insect damage, and rust incidence. The findings are accompanied by detailed maps illustrating the survey results.
