Quantifying the relationship between thermal indices and maize phenology

Abstract

Understanding the relationship between thermal indices and maize phenology is crucial for optimizing crop management practices and improving yield prediction models. This study investigates the correlation between various thermal indices, including Growing Degree Days (GDD), Heat Units (HU), and Crop Heat Units (CHU), and key phenological stages of maize. Using a combination of field data and statistical analysis, we aim to elucidate how thermal conditions influence the development and growth stages of maize.
