Growing amaranth in Germany

German food-amaranth production is a small grain and pseudocereal sector, distinct from leafy amaranth and experimental biogas crops. The strongest local evidence combines South German field trials, regional extension guidance and a recent three-grower survey; it does not support a national yield promise or a uniform planting calendar.

Scope: Grain amaranth for food in Germany, with South German observations identified by region, year and sample size. Biomass crops require a separate harvest and market plan from food grain. Updated 2026-10-07.

Planting climate heatmap

Reference period: 1996-01-01 to 2025-12-31. ERA5-Land monthly mean soil temperature at 0–7 cm, air temperature and frost days at the regional reference point (51, 10). Select a month to inspect its historical conditions.

Kaul et al. (1996) report high field emergence above 15°C. The soil-temperature screen uses that historical emergence reference as a planning proxy, not a directly measured seed-zone threshold or a validated planting forecast. Check actual field temperature, frost and seedbed conditions before sowing.5

Muted green: the temperature meets the sourced minimum and no mean frost days recorded. Neutral tiles name the temperature or frost constraint. Gray: missing data. No upper soil-temperature limit is assessed. This screen does not assess the full growing season, field drainage or crop maturity.

May: Too cold

The monthly mean is outside the lower planting limit of 15.0°C.

Keep grain amaranth distinct from leaf and energy crops

Check the German grain system before sowing1,2,3
  1. 1

    Select the grain crop

    TFZ identifies Amaranthus cruentus and Bärnkrafft for German food-grain production.

  2. 2

    Confirm the buyer

    Small lots may need cleaning, drying and specialist handling.

  3. 3

    Match the field

    Favour a warm, frost-free site with a fine, stable seedbed and manageable weed pressure.

  4. 4

    Plan combine and drying

    Arrange equipment and grain handling before the crop reaches maturity.

Grain is the documented food-crop system
TFZ describes German amaranth as sporadic production primarily for grain and identifies Bärnkrafft (*A. cruentus*) as the approved grain cultivar at the time of its guidance. Experimental whole-plant biogas production is a separate system, and TFZ says a practical recommendation for it is premature.1
Treat the market as a small regional chain
The 2025 Franken-Hohenlohe survey includes three amaranth growers on 4.5 ha. Its report describes small lots, handling costs and a developing regional value chain; it does not establish nationwide demand or a dependable margin.2

Wait for a warm, frost-free seedbed

South German field conditions to assess3,5
  1. 1

    Check frost risk

    Amaranth is frost-sensitive; wait until the local field is past damaging frost conditions.

  2. 2

    Measure seed-zone warmth

    The historical Kaul et al. paper reports high field emergence above 15°C.

  3. 3

    Prepare a fine, stable seedbed

    Regional extension guidance stresses shallow drilling and consistent seed placement.

  4. 4

    Assess weeds and equipment

    Slow early growth makes weed control and suitable mechanical access important.

Use the soil temperature as a trial finding
Kaul et al. report high field emergence above 15°C. This is a historical temperature reference, not a validated nationwide soil-temperature cutoff. Field sowing depends on current seedbed warmth, moisture, frost and cultivar; historical Stuttgart trial dates are not a current national calendar.3,5
Do not map monthly climate averages to seedbed readiness
The crop needs field-level frost and soil-temperature checks. A regional climate normal cannot show current seed-zone conditions, field drainage, weed pressure or machinery access, so this evidence does not justify a month-by-month feasible/not-feasible heatmap.3,4

Establish a uniform stand and control weeds early

Regional grain-seeding reference3,4
  • Historical German field trial40 seeds/m²Target density in one set of trials; achieved stands varied.
  • Regional extension range60 seeds/m²Upper end of a 40–60 seeds/m² regional grain reference.
Use the seed-rate reference only with its source context
RegiopAKT gives 40–60 seeds/m² for grain production; older South German experiments compared 40 and 100 seeds/m² and reported target stands near 40 plants/m². Seed size, germination, drill calibration and local weed-control equipment affect the final plan.3,4
Do not borrow an energy-crop fertilizer rate
The reviewed sources do not establish a current grain-specific nitrogen recommendation. TFZ’s energy-crop figures target whole-plant biomass; they should not be transferred to food grain. Use soil tests and current local advice, and avoid excess nitrogen that may increase lodging or delay maturity.1,3,5

Reduce shattering and dry grain promptly

German grain harvest and handling2,3
  1. 1

    Watch crop maturity

    Regional extension gives about 100–150 days, with substantial genotype and season effects.

  2. 2

    Check seed loss risk

    Mature seed can shatter before harvest; inspect the crop and combine timing closely.

  3. 3

    Harvest and clean

    Coordinate machinery and cleaning capacity for a small-lot crop.

  4. 4

    Dry promptly

    The regional guidance calls for prompt drying to about 10% moisture.

Keep the three-farm yield range in context
The 2025 regional survey reports a self-reported mean of 1.65 t/ha and range of 0.8–3.5 t/ha among three amaranth growers. This small sample is evidence that a local food-grain chain exists, not a yield target or farm budget assumption.2
Harvest and postharvest dates are local references
RegiopAKT describes September–October combine harvest and prompt drying, while historic trials show strong genotype and weather effects. Monitor crop maturity and buyer moisture specifications rather than relying on one date band.3,4

Frequently asked questions

What type of amaranth is grown for grain in Germany?
Bavarian TFZ identifies Amaranthus cruentus cultivar Bärnkrafft as the German grain cultivar at the time of its guidance. Grain production should be kept distinct from leafy vegetables and experimental biogas crops.
When is grain amaranth sown in Germany?
Regional sources describe May sowing and a historical South German field-emergence reference above 15°C. These are source- and site-specific references, not a national planting calendar.
What yield can a German amaranth farm expect?
A 2025 survey of three growers reported a self-reported mean of 1.65 t/ha and range of 0.8–3.5 t/ha. The small sample does not support a national yield promise.
How is amaranth grain harvested in Germany?
Regional guidance describes combine harvest around September–October, followed by cleaning and prompt drying. Watch for seed shattering and follow the buyer’s moisture specification.
Does the energy-crop nitrogen guidance apply to grain amaranth?
No. TFZ’s biomass guidance targets whole-plant energy crops. The reviewed sources do not establish a current grain-specific nitrogen rate.
