# Summer corn planting in RS reaches 80% of planned area, but rains delay crops

> Emater/RS-Ascar reports summer corn planting in Rio Grande do Sul has reached 80% of the 896.4 thousand hectares planned for 2026/27. Excess rain, cold temperatures and low sunlight have slowed operations and caused uneven early growth, stand failures and some replanting.
