Peru's Potato Plantings Rise 0.5% for 2025/2026, But Regions Diverge Sharply

A national increase of half a percentage point sounds unremarkable until it's broken apart by region. Potato plantings in Peru for the 2025/2026 agricultural campaign rose 0.5% in the August 2025–April 2026 period compared with the same stretch a year earlier, according to planting monitoring from Peru's Ministry of Agrarian Development and Irrigation (Midagri), reported by Agraria.pe. That modest national figure sits on top of a 5.2% jump in northern departments and a 1.1% rise in central departments, led by La Libertad, Ayacucho, Junín and Lima. The north-center split is the real signal in the data — a flat national number can still describe meaningfully different conditions on the ground depending on where a grower is farming.

Ninety percent of Peru's potato cultivation sits in the sierra highlands, and native potato varieties carry particular weight within that footprint. Peru grows more than 3,000 varieties of the tuber, offering a genetic base to the world that few other producing countries can match. The crop underpins the livelihoods of 711,000 families, concentrated in Huánuco, Ayacucho, La Libertad, Apurímac, Junín and Huancavelica. That scale of dependency is a reason planting monitoring matters beyond a single season's number — a small percentage shift nationally can still represent a large absolute change in acreage across hundreds of thousands of smallholder operations.

Potato wasn't the only crop tracked in this monitoring round. Yellow corn (maíz amarillo duro) plantings increased 3.5% against the historical average and 3.3% against the 2024/2025 campaign, with coastal growth of 9.7% driven heavily by Piura (up 43.4%) and Áncash (up 41.4%), while jungle-region plantings rose a more modest 0.4% overall — Ucayali alone grew 21.0%, even as San Martín slipped 0.9%. Yellow corn's importance runs through the poultry industry, where it supplies up to 60% of balanced feed rations and contributes the carbohydrates and carotenoids that pigment egg yolks; the poultry sector itself employs more than 460,000 Peruvians and accounts for 65% of gross livestock production value, 24% of gross agricultural production value, and nearly 2% of national GDP. Choclo (fresh sweet corn) plantings rose 3.7% against both the five-year average and the prior campaign, with Ayacucho posting the sharpest regional gain at 37.0%, followed by Áncash (10.4%) and Cajamarca (3.8%). None of these crops move in isolation from potato — all three sit inside the same basic food-basket monitoring framework, and a grower deciding what to plant next season is implicitly weighing acreage against these same regional signals.

The planting figures come out of a specific Midagri instrument: the Marco Orientador de Cultivos (Crop Guidance Framework, MOC), designed to track, promote and publicize the country's principal agricultural products and issue alerts meant to head off seasonal imbalances before they hit producers. The mechanism behind the alerts is a "semáforo de siembras" — a planting traffic-light system built for each crop against its historical series, with the historical average defined as the prior five agricultural campaigns. In practice, that means every regional percentage cited above is being measured against a rolling five-year baseline rather than a single prior year, which is what allows Midagri to flag a genuine trend shift instead of ordinary year-to-year noise.
