Soil: The best soils for sunflowers are sandy or silt loam soils, clay loam soils
with good water holding capacity have an advantage in dry years. Good
drainage is important since sunflowers do not like water-logged soils. Ideal soil
pH is between 6.0 and 7.0.
Seed Populations: For dryland low fertility soils, you can plant 18,000 kernels
per acre and up to 28,000 (irrigated, high fertility) seed population.
Planting: Soil temperatures should be near 50 degrees at planting. Seeding
depth should be 3/4 to 1.5 inches deep into a firm seed bed. The seed can be
broadcasted. Common row spacings are between 15 and 40 inches, and wide
rows can be cultivated.
Fertilizer: If you are planting after a legume crop, NPK rates of 60-40-60 are
recommended. If planting behind other crops, use 80-100 units of N.
Planting for Dove Hunts: Staggered plantings allow different maturity dates and
may benefit management of field for dove hunts.
