Grain legumes, also called pulses, are plants belonging to the family Leguminosae (alternatively Fabaceae) which are grown primarily for their edible grains or seeds. These seeds are harvested mature and marketed dry to be used as food or feed or processed into various products. Being legumes, these plants have the advantage of fixing atmospheric nitrogen for their own needs and for soil enrichment, thereby reducing the cost of fertilizer inputs in crop farming.
Crops that are harvested green for forage and for vegetables are excluded, as well as those grown for grazing or green manure. Also excluded are the leguminous crops with seeds which are used exclusively for sowing, such as alfalfa and clover (FAO, 2010).
As defined further by the Food and Agriculture Organization (2010) of the United Nations, pulses exclude those that are used mainly for the extraction of oil, e.g., soybeans. This definition, however, is presumed based on the main uses of the crop in consideration of world statistics. It does not necessarily declassify the soybean and other leguminous crops as pulse crops in certain countries. In its report entitled “Dimensions of need- Staple crops: What do people eat?,” FAO (1995) in fact listed soybean as a staple crop in China and lentil in the North Eastern region.
Grain legumes or pulses, which include beans, peas, soybeans, peanuts and lentils, are excellent sources of protein and B vitamins in addition to carbohydrate. Although the protein quality is not as good as in meat generally due to low levels of the essential amino acid methionine, this can be corrected by incorporating grain legumes with cereals in the diet (Oregon State University, n.d.). They are rich in lysine. Especially with soybeans and peanuts, they are good sources of vegetable oils which are used in the production of various products such as cooking oil, margarine, mayonnaise, and salad dressings (Hymowitz, 1990).
