Italy maize harvest faces quality warning as regional estimates remain provisional

Confcooperative Lombardia’s October 23 campaign assessment said quality problems had become widespread in Italy’s 2026 maize harvest, while the national production and quality picture remained open. Daniele Castagnaviz, the cooperative federation’s cereals chair, said more than 60% of the crop faced quality problems. The same statement relayed early regional indications of an approximately 15% production contraction in Veneto and Emilia-Romagna, and a decline of up to 3% in Lombardy. These are interim sector assessments and estimates made while harvesting continued, not completed official statistics.

The update raises two distinct questions about the 2026 season: how much maize was harvested and what quality grades the crop can meet. Quality deterioration can affect the amount usable in feed or food chains and the price received, even when total tonnage is unchanged. But the federation’s statement does not quantify in tonnes the crop affected by quality issues. Its “more than 60%” wording is a sector assessment of the share facing quality problems. It should not be treated as a direct measure of crop destroyed, discarded or lost through lower yields.

The regional production signals need the same care. The approximately 15% contraction reported for Veneto and Emilia-Romagna is an early estimate against the previous season; the source does not publish final regional totals, yield per hectare or a calculation method. The figure of up to 3% for Lombardy is an upper limit, not a confirmed 3% decline. In Piemonte, production was expected to be close to levels in previous years. Because the statement supplies neither starting nor ending volumes in a common regional table, these percentages cannot be used to reconstruct a national total.

For national production, the statement’s indication was that the outcome was expected below four million tonnes. That is a forecast expressed before the campaign was complete, not a final harvest quantity. The final data may differ once harvesting and statistical reporting are complete. The statement does not identify an official statistical series or sampling method behind this estimate. A careful account can therefore say that the cooperative sector expected a result below the threshold during the campaign, but cannot say that production had already fallen below four million tonnes.

Quality matters in part because of feed demand linked to dairy and cheese production. Stefano Pezzini, president of Confcooperative Agroalimentare Lombardia, said the protected-origin requirements for Grana Padano make local maize necessary in livestock feed. The link shows that regional maize serves a specific production chain as well as the broader commodity market. The statement does not measure stocks held by Grana Padano producers, substitution with other feed or any effect on cheese output. Those questions require separate data from producers and the supply chain.

Castagnaviz also described demand as weak, saying buyers were scarce in the market. That comment conveys the trading atmosphere during the campaign; it is not accompanied by published transaction volumes, a price index or purchase-contract data. Quality problems and weak demand may put pressure on the market at the same time, but the source does not state how prices changed or what happened to farm income. Conclusions about prices, incomes or imports require additional official series and market evidence.

CREA’s January 2026 research agenda also addresses the inputs used in maize cultivation, beyond the amount harvested. The institute identified mycotoxin biocontrol and the use of livestock manure as an alternative to mineral nitrogen fertilizer as two important research topics. CREA noted environmental and regulatory pressures around urea, a widely used fertilizer, while also describing practical challenges for organic alternatives, including application methods, mechanization, transport costs and logistics. This research agenda shows how the sector’s quality and cost questions extend to field management and environmental effects.

CREA’s National Variety Comparison Networks provide a separate source for understanding how yield data are produced. In 2025 trials, mid-to-late grain-maize hybrids averaged 14.5 tonnes per hectare, 10.3% above the previous year. Trials of early hybrids averaged 12.5 tonnes per hectare, a 14.7% rise, while whole-plant silage maize trials averaged 24.6 tonnes per hectare, up 13%. CREA also reported lower nutritional value and fiber digestibility in the silage trials. These are averages from variety trials, not regional yield statistics for farmers’ fields.

CREA’s January 2026 assessment of the maize sector offers a baseline from the previous completed harvest. It estimated Italy’s 2025 grain-maize area at about 540,000 hectares, 9% above the 495,000 hectares reported for 2024. Production rose 12%, from 4.9 million to 5.5 million tonnes, while average yields reached just over 10 tonnes per hectare. Even so, CREA said that output covered only 45% of national demand. These figures do not describe the 2026 harvest; they place the new campaign outlook against the sector’s recent supply position.

The same CREA assessment put the maize trade deficit for the 2024/25 marketing year at 7.1 million tonnes and its net cost at nearly €1.6 billion. The deficit is imports minus exports, and it is not a forecast of imports in 2026. It does show how a weak domestic crop can leave feed and food chains exposed to external supply. The fact that the 2025 rebound still covered less than half of national demand helps explain why harvest quality is watched not only as a farm-income issue but also as a measure of usable domestic supply for downstream industries.

One technical dimension of maize quality is the presence of mycotoxins produced by different fungi. CREA’s 2026 assessment says conditions during the 2025 campaign favored aflatoxins and fumonisins, but Confcooperative’s statement that more than 60% of the crop faced quality issues does not identify either toxin as the cause or measure their prevalence. CREA’s monitoring network evaluates samples through laboratory analysis: its Bergamo facility tests maize grain and silage for aflatoxins, fumonisins, deoxynivalenol and zearalenone using ELISA methods, and participates in inter-laboratory comparison tests. The federation’s broad quality warning is not the same dataset as those toxin-specific results.

CREA’s technical guidance treats quality management as a chain from the field through storage, rather than as sorting after harvest alone. The guidelines say that mycotoxin contamination depends on environmental and microclimatic conditions and cannot be eliminated through a single control measure. For aflatoxins, they identify high temperatures, sensitivity during flowering and water stress among the risk factors, and recommend preventive steps such as suitable hybrid selection, sowing time and irrigation management. These are general technical recommendations; they should not be presented as causes of the regional estimates in the 2026 campaign statement.

The feed and dairy connection also needs to be described through the actual product rules. The agriculture ministry’s Grana Padano PDO specification requires at least 50% of a dairy cow’s daily ration dry matter to come from forage and at least 75% of forage dry matter to come from the milk-production area. The document lists maize among the plants usable as fresh forage and among permitted feed materials; maize silage is also permitted, with a stated exception for Trentingrana. These rules make the regional feed link concrete, but they do not specify maize’s share of the total ration or quantify any supply gap in the current season.
