Early Planting and Cold Weather Threaten Crop Yields

Planting corn and soybeans before soil temperatures reach at least 50 °F can delay germination, cause uneven emergence and increase the risk of chilling injury, leading to lower yields. Research shows optimal germination occurs at 60‑70 °F, with the best growth at 85‑90 °F, and cold, wet soils can damage seed cells and stunt seedlings.

Outdoor cannabis growers face similar challenges when unexpected cold spring nights drop to 5‑6 °C (41‑43 °F). To survive such temperature swings, growers are advised to use seed varieties bred for cold resilience, such as Dutch Passion’s Passion #1 and Snow Bud, which tolerate sharp day‑night temperature differences and maintain higher THC levels.

Both articles stress that matching planting timing and seed selection to local temperature conditions is essential for protecting crop health and maximizing harvest returns.
