As of December 25, Ukraine’s total corn harvest reached 27.5 million tonnes, collected from 87% of the planted area, according to ProAgro Group. Around 551,000 hectares of corn remain unharvested. Based on the current national average yield of approximately 7.13 tonnes per hectare, this translates into a baseline potential for additional production of about 4 million tonnes.

Importantly, most of the unharvested areas are concentrated in regions with yields well above the national average. The largest remaining areas are recorded in Sumy region (around 93,000 hectares with an average yield of 8.0 t/ha), Zhytomyr region (56,000 hectares, 7.7 t/ha), Chernihiv region (49,000 hectares, 8.8 t/ha), Kyiv region (29,000 hectares, 9.2 t/ha), and Cherkasy region (29,000 hectares, 7.0 t/ha).

Taking into account actual yields in these key regions, the combined additional harvest potential could exceed 2.3 million tonnes. When the remaining regions are included, the final upside for corn production may surpass the baseline estimate and approach 4.3–4.5 million tonnes.

Against this backdrop, corn exports through seaports have slowed, creating downward pressure on prices. Rising risks and additional costs associated with maritime exports continue to weigh on market sentiment. The spot corn index with CPT port delivery (30 days) has declined to $204 per tonne, according to Spike Brokers.

Earlier reports indicated that Ukraine’s corn exports in December 2025 could exceed 2 million tonnes. As of December 29, export documentation had been completed for 1.929 million tonnes of corn.
