Corn (Field): Base temperature 10°C, requires 1500 GDD for maturity. Field corn (dent corn) for grain production

Sample Data: This calculator uses simulated temperature data for demonstration. In practice, use actual weather station data or field measurements.

Crop Development Analysis

No temperature data available. Generate sample data or import weather data.

Agricultural Disclaimer: Growing Degree Days calculations provide estimates for crop development timing. Actual growth rates depend on multiple factors including variety, soil conditions, moisture, nutrients, and local climate variations. Use as a guide alongside field observations and local agricultural expertise. Weather data accuracy directly affects GDD calculation precision.
