Wheat is the most important grain crop. The origin of wheat is unknown. The best quality wheat is produced in areas, where the winters are cold and the summer comparatively hot.
Wheat is best adapted to fertile medium-to-heavy soils that are well drained. It is an annual or winter annual grass, which is normally self-pollinated. Wheat varieties differ greatly in winter hardiness. The most commonly used fertilizers for wheat are potash, superphosphate, and sometimes nitrogen is applied as a top dressing in spring. It makes wheat higher in protein content. All fertilizers increase the yields of wheat.
Wheat is a leading food crop of the world. Wheat is widely grown all over the world. It is grown in approximately 50 different countries. Wheat is produced mostly for grain. The time of seeding wheat varies with climatic and soil conditions. There are spring and winter varieties of wheat. The usual depth of seeding varies from 1 to 3 inches.
