Field peas are a cool season legume crop. Temperate climatic conditions are the most suitable for pea growing. Higher altitudes and cool seasons can provide excellent yields in warmer climates. Most cultivated field peas belong to the same species (Pisum sativum L.), but several subspecies have been developed to meet specific agronomic, pathological, and nutritional needs of different regions. Field peas are relatively high in crude protein 22.8%, intermediate between corn and soybeans. Starch content is slightly less than corn depending on the variety. Peas are often used as protein supplements with monogastric diets in areas where soybean meal is not readily available or costly.
