WebGDD. Growing degree days (GDD) is a weather-based indicator for assessing crop development. It is a calculation used by crop producers that is a measure of heat accumulation used to predict plant and pest development rates such as the date that a crop reaches maturity. In the absence of extreme conditions such as drought or disease, … WebTemperature or heat units are called growing degree days (GDD) and are calculated by subtracting the lower threshold temperature from the average daily air temperature. Although the lower growth limit for wheat is about 42 °F, Bauer found better correlation in the GDD predictions by defining the lower threshold temperature as 32 °F (0 °C).
