How Many Potatoes Grow on One Hectare? EU Yields Explained (2024)

The league: EU potato yields per hectare

Potato yields across the EU-27 vary by more than a factor of three on the same crop. In 2024 Denmark topped the league with 45.84 t/ha, ahead of Germany at 45.02 and France at 42.44. One caution before any league table: Eurostat publishes no official EU-27 aggregate yield line for potatoes — the indicator YLD_HUMD_EU_T_HA exists only per member state, so every EU-wide average is something the reader assembles, not something the dataset publishes.

The league therefore runs on the 26 member states that reported a yield figure for 2024; Malta reported production and area but no yield point. The Netherlands ranked fourth with 41.70 t/ha, Ireland fifth with 39.62 and Belgium sixth with 39.59. At the bottom of the table Romania recorded 13.87 t/ha, so the distance between the best and the worst national yield is 3.3-fold. The unweighted mean of the 26 national figures is 29.72 t/ha.

Yield here means harvested production at EU standard humidity divided by the recorded cropped area — the same arithmetic a grower would do, applied to official statistics, and it inherits the rounding of both the volume and the area returns. Denmark's 45.84 t/ha translates to roughly 46 tonnes from a hectare — a field the size of a football pitch — which is the image beginners can carry into the rest of this article.

Volume vs efficiency: biggest growers vs best growers

Volume and efficiency name different leaders. Germany grew the most potatoes in 2024 — 12 703.3 thousand tonnes, or 25.0% of the EU-27 total of 50 780.3 thousand tonnes — followed by France with 9 237.5 thousand tonnes (18.2%), the Netherlands with 6 366.8 (12.5%) and Poland with 5 920.2 (11.7%). Those four countries alone account for 67.4% of EU production.

The yield table reorders the field. Denmark is only sixth by volume, with 2 997.6 thousand tonnes (5.9%), yet first by yield; the Netherlands, fourth on yield with 41.70 t/ha, is third by volume with a 12.5% share. Romania harvested 1 053.3 thousand tonnes (2.1%) on the EU's sixth-largest potato area but the lowest yield, which is what drags it to the bottom of the league.

The EU-27 recorded 1 383.8 thousand hectares of potatoes in 2024: Germany 282.2 thousand hectares (20.4%), France 217.7 (15.7%) and Poland 196.2 (14.2%) — the top three hold 50.3% of the area. Area is also where the decade's biggest national moves sit: Germany expanded by 19.2% since 2015 while Poland contracted by 32.9%, from 292.5 to 196.2 thousand hectares.

Why commercial yields dwarf garden harvests

Commercial potato yields are the product of a full production system: certified seed, plant protection, irrigation where needed and harvest timed to the crop — and the Eurostat dataset can only record the two endpoints, area and volume. What the data does show is how wide the commercial range itself is: on the same crop and the same year, Danish fields yielded 3.3 times what Romanian fields did.

It also shows that commercial systems remain weather-exposed. The 2018 season cut yields across the northern leaders: Denmark fell 20.4% (from 43.68 to 34.75 t/ha), Germany 24.4% (46.79 to 35.38), the Netherlands 20.4% (46.00 to 36.61) and Belgium 31.4% (47.57 to 32.63); EU-27 production fell 16.1%, from 55 773.0 to 46 776.6 thousand tonnes. Across 2015-2024 the most stable of the top six was France (yield CV of 4.4%) and the least stable Ireland (10.3%).

For a garden comparison two cautions apply. First, national yield is production at EU standard humidity divided by recorded cropped area, so it carries the rounding of official returns — it is not a plot measurement. Second, the dataset records no garden data at all, so any comparison between 40-plus tonnes per hectare and an allotment harvest is arithmetic, not observation: useful for scale, not a forecast.

Allotment translation: what 45 t/ha means for a 10 m2 bed

Translating a national yield into garden scale is pure arithmetic. One hectare is 10 000 m², and 45 tonnes is 45 000 kilograms, so 45 t/ha equals 45 000 kg divided by 10 000 m² — 4.5 kg of potatoes per square metre. Denmark's 2024 league-leading 45.84 t/ha works out at 4.584 kg per m², call it 4.6 kg.

A 10 m² allotment bed scaled against these rates would carry 45.8 kg at the Danish yield, 29.7 kg at the unweighted mean of the 26 reporting countries (29.72 t/ha) and 13.9 kg at the Romanian rate (13.87 t/ha). The table extends the same conversion to the bed sizes gardeners actually plan with.

Treat these numbers as a ceiling exercise, not a prediction. National yields assume a full commercial season, a single crop on the recorded area and inputs a garden rarely matches; they also inherit the rounding of area and volume returns. A bed that yields a third to a half of these figures is not underperforming — it is a garden.

Reading the source: the indicator behind the number

All figures in this article come from the Eurostat dataset apro_cpsh1, which carries three relevant indicators: YLD_HUMD_EU_T_HA (yield in tonnes per hectare at EU standard humidity), HPRD_HUMD_EU_THS_T (harvested production in thousand tonnes) and AR_THS_HA (recorded area in thousand hectares). Production and area exist as official EU27_2020 aggregates; for yield, no EU-level aggregate is published — each league in this article was computed member state by member state.

The series are not always complete. The Netherlands has no yield points for 2021 or 2022 — eight of the ten years in the window — and Ireland misses 2017, nine of ten. Readers comparing decade endpoints for those countries are comparing the years the data covers, and the dataset records no reason for the gaps. For 2024, 26 of 27 member states reported a yield figure.

The decade view ties volume and land together: EU-27 production rose 6.7%, from 47 595.6 to 50 780.3 thousand tonnes, while recorded area fell 9.3%, from 1 525.9 to 1 383.8 thousand hectares. Dividing one by the other — an implied yield, since the official aggregate line does not exist — lifts the EU level from 31.2 to 36.7 t/ha, a 17.6% gain. That is the same division the yield indicator performs, and it inherits the same rounding of area returns.
