Following the introduction of the general BBCH scale, the specific BBCH scale for the peanut plant is presented providing crop-specific descriptions and detailed assessment instructions.The phenological development process of the peanut plant is described by periods (principal growth stages) and steps (secondary growth stages). A 2-digit decimal code suitable for data processing in crop production experiments is assigned to each developmental step.
