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 with adequate soil moisture. 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. Plant 105 days prior to hunting season to allow plants to mature. 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. |
