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. 全国向日葵调查, 包括北达科他州的油田, pointed out that stand establishment was and still is a major problem in sunflower production. 植物相隔太远, 靠得太近, 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).
