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.
Use of Herbicides:
For Non-Clearfield Hybrids - Use Prowl and/or Dual as a pre-emerge herbicide. Spartan can be used also,
but not tilled in or used after emergence. Rainfall is needed within 48 hours for adequate pre-emergence
For Clearfield Hybrids - Use the pre-emerge herbicides listed above and follow up with 4 oz. of Beyond per
acre. The JD style plates you need for a size 3 or 4 sunflower are B-050-24 and you need a BFR-40 filler
Select herbicide can be applied over the top for grasses on both Clearfield and Non-Clearfield Hybrids.
