Text В Legumes for Protein and Oil
Cereals are the main source of energy in the human diet. But they do not contain much protein. Edible legumes are high in plant protein which is necessary both for man and farm animals.
The main edible legumes grown in the United States include soybeans, field beans and field peas. Soybeans are now one of the leading farm crops in this country. Soybeans area has increased and now this crop is economically as important as corn.
The soybean plant is adapted to different soil and climatic conditions. There are many varieties of this crop. Some of them are adapted to northern and some to southern conditions.
Soybeans are mainly grown for forage, grain or as a vegetable. They can also be grown as a green manure crop. As a forage crop soybeans are used for pasture, hay and silage. Soybean grain is highly nutritious and many human foods are produced from it. The protein content of soybean seed varies from 30 to 50 percent and the oil content from 15 to 25 percent. The grain can be processed into oil used either as human food or as industrial material.
The crop for grain should be harvested when seeds are low (низкий) in moisture, not more than 13 percent. In regions where soybeans are harvested with high moisture content air ventilation should be provided in the storage.
