CROP DEVELOPMENT: Emerges 5 to 7 days after planting. Begins flowering about 5 weeks after planting. Optimum seed set period is during weeks 5 - 7 after planting. Makes many flowers, but not all will set a seed. Wilts in hot weather, not real drought tolerant. Matures in 75 to 90 days.

ROOTING DEPTH: 18 - 24 inches.

SOILS: Adapts to a wide range of soil types. Prefers medium texture soils. Performs well on poor soils. Soils that crust easily can cause emergence problems.

PLANTING RATE: 45 to 60 lbs/acre, 6 or 7 inch row spacing.

PLANTING DATE: May 25 to June 15. Planting up to July 1 has occurred in North Dakota, but yields are reduced. Buckwheat is not frost tolerant at any stage.

PLANTING DEPTH: 1 to 2 inches.

FERTILITY: Nitrogen: 49 lbs of N per 1000 lbs. of yield goal (soil plus applied).
Phosphorous use is similar to wheat (use of starter is a good practice).

WEED CONTROL: No chemicals registered in U. S. Buckwheat is usually quite competitive.

CHEMICAL CARRYOVER: Sensitive to carryover of treflan, atrazine, sulfonylurea products (e. g. Glean, Ally), Tordon, Assert.

ROTATION: Between small grains.

INSECTS: Aphids (usually not a big problem). Grasshoppers occasionally cause damage.

DISEASES: Subject to Rhizoctonia root rot (not reported often).

HARVEST: Swath when the top cluster of seeds are 75% ripe. Swath when field is damp to reduce shatter loss. Swath immediately after a frost to reduce shatter loss. Stores safe at 14% to 16% moisture content when seed is clean of foreign material.

VARIETIES:  Koto, Koma, and Green Testa

MARKET: Used in Japan for milling into flour. Flour is used in buckwheat (soba) noodles.

TYPICAL YIELDS: 1000 to 1500 lbs/acre. Yields up to 2000 lbs/acre reported. Depends upon the environment in a given region.

VARIABLE COSTS: $25.00 to $40.00/acre for seed, fertilizer, fuel, repairs, etc.

CROP DEVELOPMENT: Emerges 7 to 10 days after planting. Well adapted to North Dakota. Flowering occurs 30 to 40 days after planting, and can occur for several weeks depending upon temperatures. Pods are long with many seeds. Matures in 90 to 95 days. Typical plant height is 36" to 48".

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

PLANTING RATE: 4 to 6 lbs/acre. There are approximately 180,000 seeds/pound.

PLANTING DATE: mid-April to early May. Seedlings are frost tolerant.

SEEDING DEPTH: 0.5 to 1.0 inches

FERTILITY REQUIREMENTS: 65 lbs. of N per 1000 lbs. of yield. Similar to small grains in phosphorous use. Us of 10 to 15 lbs/acre of sulfur is highly suggested.

WEED CONTROL: Treflan is labeled for weed control.

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.

INSECTS: Flea beetles (not near as serious as in canola - usually not treated), cutworms.

DISEASES: Sclerotinia (white mold), downy mildew, alternaria. Most are of minor importance if sound rotation practices are followed.

HARVEST: Swath when crop is 95 to 100% ripe. Green seeds do not change color, and can result in grade discounts. Use a roller to prevent swaths from rolling in the wind. Harvest during cooler parts of the day to reduce shatter loss. Storage moisture is 9%.

MARKETS: Hot mustard sauces and condiments.

TYPICAL YIELDS: 1000 to 1500 lbs/acre. Yields of 2000 lbs/acre have been obtained in ND.

CROP DEVELOPMENT: Emerges 7 to 10 days after planting. Well adapted to North Dakota. Flowering occurs 30 to 40 days after planting, and can occur for several weeks depending upon temperatures. From 2 to 6 seeds can be found in a given pod. Matures in 90 to 95 days. Typical plant height is 30" to 40".

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

PLANTING RATE: 10 to 14 lbs/acre.

PLANTING DATE: mid-April to early May. Seedlings are frost tolerant.

SEEDING DEPTH: 0.5 to 1.5 inches

FERTILITY REQUIREMENTS: 65 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 highly suggested.

WEED CONTROL: Treflan is labeled for weed control.

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. Rooting depth similar to small grains.

INSECTS: Flea beetles (not near as serious as in canola - usually not treated), cutworms.

DISEASES: Sclerotinia (white mold), downy mildew, alternaria. Most are of minor importance if sound rotation practices are followed.

HARVEST: Straight combining is preferred. Harvest when crop is 100% ripe. Green seeds do not change color, and result in grade discounts. Harvest during cooler parts of the day to reduce shatter loss. Storage moisture is 9%.

MARKETS: Table (hot dog) mustard, used also as a binding agent in processed meats.

TYPICAL YIELDS: 1000 to 1500 lbs/acre.
