A meta-analysis of 132 studies found drip irrigation gives the best water productivity for potatoes. Under water-saving regimes, drip lost 15% of yield against 26% for sprinklers.
Storage losses to the potato tuber moth reach 50–100% in warm countries. Cooling below 10°C, deep planting and clean tubers are the main defences; plant powders showed results in Egypt.
Beyond Breeding: Resource-Saving Technologies and Biological Inputs in Polish Potato Production Alongside breeding advances, Polish potato farming is increasingly embracing technologies aimed at saving resources and improving crop resilience. A notable example is the ploughless, or "no-plough,"…
A Norwegian study found three cultivars exceeded 200 mg/kg glycoalkaloids after 36 hours of retail light. Greening was four times faster at 20°C than at 6°C.
EU seed potato grades set virus tolerances from 0.2% for grade S to 6% for class B. Scotland prefers much stricter limits for PVY, PVA and leaf roll.
EU rules for potato brown rot require 200-tuber tests, destruction of infected lots and a four-year ban on host crops on infected fields. Egyptian ware imports face extra checks until 2029.
University of Wisconsin trials link higher tuber calcium to fewer cases of internal brown spot and hollow heart. Split calcium doses during bulking gave the best results.
A review for the UK potato levy board found compaction cut yields in 13 of 16 trials. Wheel loads above 3.5 tonnes and high tyre pressures push damage deep into the subsoil.
UK and Irish storage guides use a 4°C rule for ventilation at loading. Airflow, pull-down speed and a warm pile top keep water off tubers in the first weeks.
EU rules require processing potatoes to be stored above 6°C. US guidance and a 2024 Kenyan study show how warmer storage and reconditioning cut reducing sugars and lighten chips.
Life-cycle studies put fresh potatoes among the lowest-carbon staple foods. Processing, freezing and frying raise the footprint, and cooking at home can outweigh the farm.
Research on drone and field cameras shows high accuracy for visible late blight. Early detection before spots appear is harder, and models trained in the lab lose accuracy in the field.
