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

Use of Herbicides:  

Herbicides can be used to control weeds and maximize
sunflower grain yield.  Clearfield hybrids produce more seeds
than Peredoviks.

For Peredoviks and Non-Clearfield Hybrids - Use Prowl and/or
Dual as a pre-emerge herbicide. Spartan can be used, but not
tilled in or used after emergence. Rainfall is needed within 48
hours for adequate pre-emergence herbicide control.  

For Clearfield Hybrids ONLY - 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 plate.  Select herbicide
can be applied over the top for grasses on both Clearfield and
non-Clearfield hybrids.  ALWAYS READ AND FOLLOW
