In short
Worldwide, sunflower seed yield averaged 1.82 tonnes per hectare in 2024 according to FAO data, and national averages ran from about 1.1 t/ha in Spain to 3.0 t/ha in China.
Three things explain much of the spread: water between flowering and seed fill, drought years in rainfed regions, and soil-borne problems such as broomrape. Planva keeps the yield of every field and season in crop rotation, so a farm can set its own history beside these national figures.
Sunflower yield by country, 2022 to 2024
FAO publishes national averages in tonnes per hectare. The table shows Black Sea and Central Asian producers, other large growers, the two ends of the range, and the world average. A national average hides irrigation, hybrid mix and region, so treat it as a reference point and not as a target.
| Country | 2022, t/ha | 2023, t/ha | 2024, t/ha |
|---|---|---|---|
| Kazakhstan | 1.20 | 1.10 | 1.46 |
| Turkey | 2.60 | 2.31 | 2.26 |
| Ukraine | 2.16 | 2.45 | 2.18 |
| Argentina | 2.07 | 2.05 | 2.11 |
| Romania | 1.93 | 1.87 | 1.21 |
| Bulgaria | 2.33 | 2.05 | 1.77 |
| Hungary | 1.89 | 2.92 | 2.67 |
| France | 2.07 | 2.51 | 1.96 |
| United States | 1.97 | 2.00 | 1.87 |
| Spain | 0.95 | 1.09 | 1.10 |
| China | 2.79 | 2.83 | 3.01 |
| World | 1.84 | 1.96 | 1.82 |
Individual countries swing far more than the world average does. Hungary went from 1.89 t/ha in 2022 to 2.92 t/ha in 2023, and Romania fell from 1.87 t/ha in 2023 to 1.21 t/ha in 2024. Reported values come from national statistics, so treat single-year jumps as a prompt to check the source.
Water from flowering to seed fill
NDSU Extension states that a water shortage between flowering and maturity hurts sunflower yield more than a shortage at other times. In its summary of North Dakota trials from the late 1970s, irrigated sunflower averaged about 3.6 t/ha against 1.3 t/ha without irrigation. In a wetter year the two were close, at about 2.5 and 2.6 t/ha, and white mold was cited as one reason. The data are old, so read them for the pattern. Irrigation matters in dry years and adds little in wet ones.
For irrigated production NDSU recommends 24,000 to 28,000 plants per acre in 30-inch rows, which is about 59,000 to 69,000 plants per hectare. That is a guide for one irrigated system. For rainfed fields and your own hybrids, use your regional recommendations.
A drought year in a major region: Turkey, 2025
USDA reported in September 2025 that the sunflower area harvested in Turkey was projected at 760,000 ha, up on the year before, yet production was revised down to 1.2 million t because of extreme dry weather. Dividing one figure by the other gives roughly 1.6 t/ha, against the FAO value of 2.26 t/ha for 2024. The two numbers come from different sources and are not strictly comparable, but the direction is clear.
Thrace normally supplies half of the national sunflower crop. Farmers there reported yield losses of half or more against the long-term average, and USDA expects some of them to move toward canola and barley. Central Anatolia and the Cukurova region also lost yield, though less.
Broomrape: a limit that averages hide
Broomrape (Orobanche cumana) is a parasitic plant that attaches to sunflower roots. AgroAtlas says it occurs wherever sunflower is grown and that its seeds persist in soil for up to 12 years. A 2014 trade-press review puts seed viability above 20 years. The sources differ, so plan on a long gap between sunflower crops.
The same review reports infestation about four times higher when sunflower returned to a field after 2 years than after 6. It says few farms accept growing sunflower on a field only once in 7 to 10 years, and it cites a seven-field rotation with corn as the best prevention. It also describes more virulent races that attack hybrids bred against older ones. Check the resistance claim of a hybrid against the races present in your region.
Setting a yield reference for your own fields
- Use your own history first. Three to five seasons of each field, with the crop that came before sunflower, say more than any national average.
- Split by water. Keep irrigated and rainfed fields apart. Their averages do not mix.
- Write down the basis. Note whether yield is per sown or per harvested hectare, and the moisture the weight refers to.
- Mark the bad years. A drought or broomrape year belongs in the record together with its cause.
How this works in Planva
- Crop rotation by season. Crop, variety, sowing and harvest dates, yield in c/ha and harvest in tonnes for each field. Ten c/ha equal one t/ha.
- Rotation map. A crop filter on the map prints to PDF or JPEG with an area summary.
- Seed catalogue. Reproduction, germination, 1000-seed weight, maturity group and purity for each variety.
- Agroplans. Seed held by rate or quantity, plan and actual.
Planva records these facts. It does not set yield targets or give agronomic recommendations. Rotation intervals are covered in the crop rotation guide, and the platform is described on the farm management software page.

Common questions
FAO puts the 2024 world average at 1.82 t/ha, with national averages from 1.1 to 3.0 t/ha. A good figure for your farm depends on water, hybrid and region, so compare it with your own field history and your regional recommendations.
