In 2025, Paraná exported the largest volume of corn in its history. Shipments exceeded 5,36 million tons. This result indicates a 163% increase compared to the previous period. Revenue surpassed R$ 6 billion, approximately US$ 1,15 billion.
The state is the second largest national producer of the cereal. Domestic consumption absorbs most of the production. Foreign trade utilizes the surplus harvest.
The performance came after a bumper crop. The combined total of the first and second harvests exceeded 20,6 million tons in 2025.
Iran led the purchases of corn from Paraná, accounting for 51% of the exported volume.
The export sector is assessing changes for the next cycle. The conflict in the Middle East creates a risk of logistical and commercial bottlenecks. This scenario could hinder the flow of shipments in the short term.
Rice harvesting is progressing in Paraná. Producers are removing the crops at a steady pace. Expectations point to a production of 147 tons. Half of the volume has already been harvested.
The result could exceed the 2025 harvest by 10%, when the state harvested 134 tons.
The approach of autumn reduces the risk of heavy rains. This scenario decreases the possibility of new floods in the Ivaí River, a problem recorded in the two previous harvests.

The states of Rio Grande do Sul, Santa Catarina, Paraná, Minas Gerais, and São Paulo account for the entire national harvest. The municipality of Caxias do Sul is responsible for 28,1% of the production.
Paraná is the third largest producer in the country. The state recorded an area of 130 hectares and a production of 2,1 tons in 2024. The gross value of production reached R$ 11,1 million.
Production in Paraná is concentrated in the metropolitan region of Curitiba. This area accounts for 70% of the state's production. The municipality of Araucária leads in cultivation.
At the Ceasa wholesale market in Curitiba, the average price of common domestic pears reaches R$ 70 per 20-kilo box. The Yari variety reaches R$ 140 per box. The imported product from Argentina reaches R$ 180 per 18-kilo box.
