Reevaluation of the degree day base 60°F concept in US cotton (Gossypium hirsutum L.) production
Agronomy Journal, Volume 115, Issue 6, Page 3045-3061, November/December 2023., 2023 Abstract Cotton (Gossypium hirsutum L.) management decisions to abet early growth, fruit set, boll maturation, and harvest preparation are often facilitated by prediction of the date when critical developmental stages are reached. In the United States, growing degree days calculated with a base 60°F (DD60s) are commonly used to predict cotton ...
