In the absence of extreme conditions such as unseasonal drought or disease, plants grow in a cumulative stepwise manner which is strongly influenced by the ambient temperature. Growing degree days take aspects of local weather into account and allow gardeners to predict (or, in greenhouses, even to control) the plants' pace toward maturity. Unless stressed by other environmental factors like moisture, the development rate from emerg… http://blog.mesonet.org/agriculture/summer-crop-heat-units-in-2016/ WebAug 10, 2024 · Corn Heat Units. Corn heat units are a measurement of useful heat for the growth and development of corn.
