What is the study of vegetables referred to as?

The study of vegetables is referred to as olericulture. This branch of horticulture specifically focuses on the cultivation, production, and management of vegetables. It covers various aspects such as plant breeding, pest management, soil health, and post-harvest handling, which are all crucial for growing and maintaining vegetable crops effectively.

In contrast, pomology is the study of fruit cultivation, agronomy deals with field crops and the broader aspects of agricultural science, and aquaculture is focused on the farming of aquatic organisms, such as fish and shellfish. Each of these fields has its own distinct focus and practices, making olericulture the correct term when specifically discussing vegetables.
