What are GDD and how are they calculated? Growing degree-days are a temperature-derived index representative of the amount of heat that the plants are exposed to, which in turn is directly related to the rate of growth and development of the plant. GDD are calculated several ways, so it is important to make sure GDD are calculated using the same formula that was used to establish the relationship you will use to harvest alfalfa. For instance, different base temperatures are used for different crops, and corn uses a different method of calculation entirely. Alfalfa GDD used for recommendations in this article are calculated by averaging the maximum and minimum temperature (° F) for a given day (24-h period) then subtracting the base temperature of 41°F to get the number of GDDs for that day. Daily GDD for days with an average temperature less than 41°F are set equal to 0. Finally, a seasonal total is then obtained by summing the daily growing degrees from March 1st through the current day.
