Planting Sunflower with Attention to Details
This page was adapted from the article, "Planting Sunflower with Attention to Details," which appeared in Crop & Pest Report on June 16, 2022.
Paying attention to details is very important to obtain the desired sunflower yields.
Poor seedbed conditions and planting issues may result in uneven stands of sunflower. The National Sunflower Survey, which includes North Dakota fields, pointed out that stand establishment was and still is a major problem in sunflower production. Plants too far apart, too close together, doubles, and large gaps in the rows were common in 17% of the 1245 surveyed fields (Figure 1), and can result in reduced yield potential. Based on observations from 2006 to 2017, the average yield of fields without limiting factors was 2,171 pounds per acre and the fields with plant spacing issues had a significantly lower yield of 1,732 pounds per acre (about 20% lower) (Hansen, 2020, page 68).
