The Corn Growing Degree Day (GDD) decision support tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year. GDD projections, combined with analysis of historical analog data, can help you make decisions about:

Welcome to the Corn Growing Degree Day (GDD) decision support tool. This tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year. GDD projections, combined with analysis of historical analog data, can help you make decisions about:

Corn growth stages can be estimated using corn growing degree days (GDD) accumulated daily from the date of planting. Corn GDD are calculated by taking the maximum daily temperature plus the minimum daily temperature to determine the average temperature in a 24-hour period.

Corn growing degree days (GDD) are calculated by subtracting the plant's lower base or threshold temperature of 50 °F (10 °C) from the average daily air temperature in °F or °C. Average daily air temperature is calculated by averaging the daily maximum and minimum air temperatures measured in any 24-hour period.

Welcome to the Corn Growing Degree Day (GDD) decision support tool. This tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year. GDD projections, combined with analysis of historical analog data, can help you make decisions about:

Track real-time and historical GDD accumulations, assess spring and fall frost risk, and guide decisions related to planting, harvest, and seed selection. This innovative tool integrates corn development stages with weather and climate data for location-specific decision support tailored specifically to agricultural production.

2024年4月22日 · Growing degree days (GDDs) are a more reliable method to predict corn emergence and development than calendar days. Start calculating GDDs daily the day after planting.

2017年1月1日 · The Corn Growing Degree Day (Corn GDD) tool is a web-based product that can provide decision support on a variety of issues throughout the entire growing season by integrating current conditions, historical climate data, and projections of Corn GDD through the end of the growing season based on both National Weather Service computer model ...

The corn growth stage model is a heat-unit or growing degree-day (GDD) model in which corn’s growth and development is based on the plant’s physiological response to temperature. The corn stage model is initiated by assuming an average planting date, and accumulated GDD heat units are then calculated and scaled according to corn growth ...

The most common temperature index used to estimate plant development is growing degree days (GDD) which are calculated from the daily maximum and minimum air temperature. Growing degree days have proven useful for crop consultants, producers, and scientists who use them to predict plant development rate and growth stage.
