Confection Sunflower Production


Compliments of MINN-DAK Growers Ltd.

CROP DEVELOPMENT: Emerges 7 to 12 days after planting. Flower buds appear 30 to 40 days after planting. Flowering occurs about 55 to 65 days after planting, and lasts for 7 to 10 days, depending upon temperature. Maturity occurs about one month after flowering is completed. Matures in 95 to 110 days, depending upon hybrid and accumulated growing degree days (GDD's). Typical plant height is 60 inches to 90 inches.

SOILS: Adapts well to many soils. Fertile, well drained soils are usually best.

PLANT POPULATION: When seeded as a row crop in 30 inch rows, the desired plant population is 15,000 to 18,000 plants per acre. Seed rates of 3 to 5 lbs/acre are typically sufficient to achieve these populations, depending upon seed size. There are approximately 4,300 seeds/pound.

PLANTING DATE: Early May to late May is typical. Seedlings have some frost tolerance.

SEEDING DEPTH: 1.5 to 2.5 inches.

FERTILITY REQUIREMENTS: 50 lbs. of N per 1000 lbs. of yield. Similar to small grains in phosphorous use. Use of 10 to 15 lbs/acre of sulfur is suggested.

WEED CONTROL: Soil applied herbicides include Eptam, Sonalan, trifluralin (Treflan), and Prowl. Post emergence options include Assert and sethoxydim (Ultima 160).

CHEMICAL CARRYOVER: Sensitive to carryover of sulfonylureas (e. g. Glean, Ally), also sensitive to atrazine and picloram (Tordon).

ROTATION: Usually between small grains.

WATER USE: Fairly drought tolerant, deep rooted crop.

INSECTS: Sunflower midge, red seed weevil, gray seed weevil, stem weevil, sunflower beetle, banded sunflower moth. Numerous insecticides are labeled for insect control.

DISEASES: Sclerotinia (white mold), downy mildew, alternaria, rust, head rot, phoma black stem. Diseases are typically managed by using good rotation practices. Seed treatment with Apron is beneficial in preventing downy mildew.

HARVEST: Sunflowers are typically harvested 30 to 45 days after maturity, since it takes this long for the plant to dry down. Use of sunflower pans on a straight header attachment is the most common practice. Cylinder speeds of 300 to 500 rpm are typical, depending upon moisture content. Typical concave settings are 1" in front and 0.75" in rear. Typical sieve settings are 1/2" to 5/8" on top, and 3/8" on bottom. Seed moisture should be less than 10% for storage. It is important to avoid cracking and hulling. Drying is quite typical.

MARKETS: Edible whole sunflower seeds. Hulled seeds (or nut meats) are used in breads, cereals, salad toppings, and other condiment applications.

TYPICAL YIELDS: 1000 to 1500 lbs/acre. Yields of 2000 lbs/acre are possible.

VARIETIES: Numerous hybrid varieties are available.
