Planting corn to choose a good variety is the key to high yield, you can select the seed according to the local cumulative temperature conditions, generally speaking, the long growing period of the varieties of good yield performance, higher yield potential. Corn is the same, there are ordinary corn, sweet corn, white and yellow, geographically different, soil, climatic conditions, water conditions, etc. There are differences, choose the right varieties.

Planting corn field management is a complicated process, as long as the choice of good varieties of diligent management of reasonable fertilization and timely elimination of weeds properly irrigated, corn will be planted and big and beautiful and no insects to eat.
