Growing degree-days: one equation, two interpretations

Agricultural and Forest Meteorology, 1997
Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [(TMAX + TMIN)2]−TBASE, where TMAX and TMIN are daily maximum and minimum air temperature, respectively, and TBASE is the base temperature. Two methods of interpreting this equation for calculating GDD

Can Growing Degree Days and Photoperiod Predict Spring Wheat Phenology?

Frontiers in Environmental Science, 2017
Wheat (Triticum aestivum) production in the rainfed area of Pothwar Pakistan is extremely vulnerable to high temperature. The expected increase in temperature due to global warming should result in shorter crop life cycles, and thus lower biomass and ...

Quinoa Phenological Development Modeling Based on Field Data [PDF]

پژوهشهای زراعی ایران, 2023
IntroductionClimate change is rapidly degrading the conditions of crop production. For instance, increasing salinization and aridity is forecasted to increase in most parts of the world. As a consequence, new stress-tolerant species and genotypes must be

Increasing maize yields in Northeast China are more closely associated with changes in crop timing than with climate warming

Environmental Research Letters, 2021
An understanding of mechanisms that underlie the steady increase in crop yields over recent decades is important for promotion of future sustainable yield gains and maintenance of future food security.

Model Development of the Phenological Cycle from Flower to Fruit of Strawberries (Fragaria × ananassa)

Agronomy, 2023
Strawberries are a very important economic crop; thus, a lot of research has been conducted on several production areas. However, phenological performance is still lacking information, especially when it comes to modeling.
