Agricultural Plant Sciences: field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of plant agriculture; the study of the life and development of edible, ornamental and native vegetation, including grasses, vines, shrubs and trees. Agriculture sciences seek to feed the world's population while preventing biosafety problems that may affect human health and the environment. This requires promoting good management of natural resources and respect for the environment, and increasingly concern for the psychological well being of all concerned in the food production and consumption system.
