Vigna is a promising vegetable crop widely used in tropical and subtropical regions of the world. Its genus contains from 57 to 200 species, many of which are already included in commercial production and have significant economic importance for the population's nutrition. Key representatives include cowpea (Vigna unguiculata), mung bean or golden bean (Vigna radiata), and mung (Vigna mungo). These species are valued for their high content of protein, vitamins, and minerals, as well as for their ability to grow under high temperatures and poor soils.
Vigna crops differ in versatility: practically all parts of the plant - from young sprouts and leaves to immature green beans and mature seeds - are used for food. This makes it a valuable source of nutrition throughout the growing season. Yields vary from 0.5 to 5 t/ha for grain and from 0.9 to 1.6 t/ha for green beans, which confirms its productivity even under unfavorable conditions.
Vigna varieties have a number of practical advantages. They are low-growing, easily grown after manure and fertilizers, especially potassium and superphosphate. In China, a popular variety has beans 0.5 m long, and on one bush can give more than 3 kg of fruit. In addition to culinary applications, Vigna is traditionally used in folk medicine for the treatment of diabetes, cholecystitis, pancreatitis, anemia, and angina. Auxiliary properties make it a valuable addition both to the diet and to a healthy eating system.
