An AHDB review shows chitting cut time to emergence by 8–10 days and can bring maturity up to two weeks earlier. A 2024 study found storage at 17°C cut yield of one variety by up to 30%.
On sandy soil in Quebec, irrigation increased nitrate leaching under potatoes by 52%, and coated urea leached more than a split programme. Extension advice links nitrogen timing to crop uptake.
In a Manitoba rotation trial, potato-canola yielded 95 cwt/acre less than three- and four-year rotations, and vascular wilt hit most plants. Other studies show the break crop also changes yield.
International standards require ware potatoes to have cured skin, no abnormal moisture and at most 10% defects in Class I. Packs up to 5 kg may be limited to a 30 mm size spread.
A 70×30 cm layout gives about 47,600 plants per hectare. That means 0.84 kg per plant for 40 t/ha and 1.26 kg for 60 t/ha. Research shows how stems and seed size decide tuber numbers.
Canada's new bacterial ring rot directive for seed potatoes takes effect on October 12, 2026. It keeps zero tolerance and sets sample sizes of 100 to 800 tubers by field size.
Idaho growers are digging a smaller crop in 2026. Planted area fell to 298,915 acres, and growers expect yields well below last year's 440 cwt per acre, while quality stays good.
Iceland harvested 8,300 tonnes of potatoes in 2025, Eurostat data show, after only 5,514 tonnes in 2024, the smallest crop since 1993 according to Hagstofa. About 70% of potatoes grow in Þykkvabær.
Irish growers harvested 384,900 tonnes of potatoes in 2025 on 8,900 hectares, official data show. Higher yields kept output up while the area kept falling.
ESPG data show that seed potato multiplication in the Netherlands, France, Germany, Scotland, Belgium and Denmark covers 105,155 ha in 2026. Belgium and Scotland cut the most, and French fry varieties lost 1,338 ha.
HZPC France has started building a greenhouse in Ruisseauville that should produce up to 2 million mini-tubers, the company says. The aim is full autonomy in early seed generations.
Czech potato growing is increasingly turning to precision and "smart" technologies. On a farm in Rantířov, a variable-rate planting system — described as unique in the country — divides fields into zones using yield maps and satellite…
