Agronomy was traditionally defined in the context of a speciality area of arable agriculture emphasizing field crops. While breeders attempt to match varieties to the environment, agronomists attempt to adapt them to the environment and management. Agronomy, therefore, is the cornerstone of all crop productivity which must be driven by the necessary education, training, research and capacity building in light of the following imperatives: use of improved seed and other inputs, knowledge in plant and cell physiology, management of rhizosphere dynamics, decision-making related to biological and environmental constraints. In the changing times, emerging interest in precision agriculture and the sensitivity of agriculture to climate widens the scope of agronomic education, training and research.
