Umka, Yuliya, Briz and Lileya yield over 30 t/ha with more than 75% marketable tubers in the island's humid monsoon climate, the Belarusian potato centre says.
Finland has developed several well-known potato varieties, with Pito and Kulta standing out as the most significant achievements of the country's breeding programs. These varieties emerged from systematic Finnish breeding efforts that were actively pursued throughout the…
University of Minnesota guidance advises boron for potatoes only on soils testing 0.4 ppm or less, applied to the soil. Florida advises 1.5 lb of boron per acre on deficient soils and testing every two years.
A 2025 Indian field study sets the critical soil magnesium level for potatoes at 42 mg/kg. University of Minnesota guidance advises magnesium on soils testing below 100 ppm, with the highest rate below 50 ppm.
Extension specialists say potato seed should go into soil of at least 45°F (about 7°C) and rising. In colder soil, emergence slows sharply and seed decay and Rhizoctonia risks grow.
Trials in Turkey and Serbia and a CIP project in Rwanda show that aeroponics produces several times more seed potato minitubers than pots or beds. Results depend strongly on variety and plant density.
Simulated hail trials in Washington and Colorado show that potato yield loss depends on both defoliation level and growth stage. Total loss of leaves at early bulking cut yield by up to 62%.
Recombinant strains of potato virus Y now make up more than 90% of US isolates. In Washington trials, infected plants produced 22% to 32% cracked tubers.
A study of 105 field trials found that potato yields fell 12% to 61% when weeds were not controlled. The farm-gate loss would reach US$465 million in the US and US$61 million in Canada.
Extension advice says potato vines should be dead for 10 to 21 days before digging. A 2025 Washington State study shows how skin strength differs by variety.
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.
