What is the primary purpose of agronomy?

The primary purpose of agronomy is to improve the production and use of plants for food, fiber, and fuel. Agronomy encompasses a wide range of scientific approaches, practices, and innovations aimed at optimizing crop yield and enhancing the efficiency of agricultural systems. This field focuses not only on the cultivation of crops but also on soil management, pest control, and sustainable agricultural practices. Agronomists work to develop methods that can increase food security and provide essential resources while considering environmental impacts and resource sustainability.

In the context of the other options, while studying the effects of climate change on crops is important, it is more of a sub-discipline within the broader field of agronomy rather than the primary focus. Developing new plant species for aesthetic purposes and creating pest-resistant plants represent specific applications of agronomic science but do not encapsulate the overarching goal of improving production and utilization of crops for essential human needs.
