Wheat
Wheat is the most important grain crop in the world. It is known to have been grown extensively in Asia, Europe and in the northern part of Africa from time immemorial.
Wheat belongs to the grass family. It is one of the most valuable plants. Wheat is adapted to a very wide range of both soil and climatic conditions. Only barley, potatoes and a few other crops grow under colder conditions than wheat. On the other hand, no part of the earth is too hot for the production of wheat if the climate is not too humid. Wheat cannot be grown successfully in areas where both warm and humid conditions prevail, because such conditions favour the rapid development of destructive diseases.
Most of the wheat that is grown is made into flour. The flour is used for making different products such as white bread, cakes, etc. A small amount of wheat is also used in the manufacture of dextrose and alcohol.
Wheat is an excellent food for livestock; but because of its importance as human food, only a small part of the total production is used for this purpose.
The by- products derived from the milling of wheat into white flour represent 25 to 30 per cent of the total weight of the grain. All the by- products are higher in content of protein than wheat itself and serve as a valuable protein supplement in many livestock rations.
Perfect crops of wheat can be grown on heavy loams and clays. When wheat is grown on peaty soils the quality is usually poor, while the yield of straw is very large.
