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.
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,"…
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.
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.
Field and glasshouse studies show that trap crops and brassica biofumigation can reduce potato cyst nematodes, but results range from 30% to almost 100% and depend on soil and crop establishment.
Eleven on-farm trials near the Great Lakes found that potato response to phosphorus falls as soil phosphorus rises. An earlier Minnesota study showed that phosphorus adds tubers, but many of them are too small to sell.
FAO data show a gap of more than ten times between the highest and lowest national potato yields. Research led by the International Potato Center names poor seed as the main cause in Africa.
FAOSTAT data for 2024 put world potato output at 390.4 million tonnes. Ten countries grow two thirds of it, and Asia's harvest is almost nine times bigger than in 1961.
Monsoon rain and Hurricane Polo have slowed field work and planting permits in northern Sinaloa, an important potato area. Dams are fuller than a year ago.
A provincial seminar in Miramar heard that potato growers in south-east Buenos Aires spend US$7,000–9,000 per hectare, while income is still below costs.
Peru's July potato production fell 19.6% as Arequipa's crop collapsed, but Lima's main wholesale market received almost the same volume as a year earlier.
