What is the primary purpose of Growing Degree Days (GDD) in agriculture?

The primary purpose of Growing Degree Days (GDD) in agriculture is to estimate the growth and development of plants. GDD serves as a crucial metric that helps farmers and agronomists assess how temperature influences biological processes in plants. By accumulating temperature data over a growing season, GDD enables the prediction of key developmental stages, such as germination, flowering, and maturity. This information is vital for optimizing planting schedules, managing crop inputs, and determining the appropriate time for harvest.

The GDD calculation is based on the understanding that plants develop at varying rates depending on temperature conditions. This relationship helps in making more informed decisions regarding crop management practices, ensuring that crops develop optimally and yield effectively.
