Crop Science is concerned with the application of biological, chemical and physical principles to crops and cropping systems for conversion into food, feed, pharmaceuticals and ornamental commodities. Crop Science examines agronomic crop plants, their growth habits and their genetic improvement. It also considers the techniques to enhance a plant’s ability to convert sunlight into usable energy, fight off diseases and insects, and produce crops that are economically and environmentally sustainable. In addition to teaching and research, specialists in Crop Science offer their expertise in agrochemical, seed, grain, nursery and food processing companies. Others work as private farmers or professional consultants.
