Many important crop plants complete their life cycle in one growing season. Such plants are known as annuals. Some annuals are spring annuals planted in spring and harvested in autumn. There are also winter annuals planted in autumn and harvested next summer. Winter wheat is an example of winter annuals and corn is a typical spring annual.
Some plants start their growth in one season but produce seed and die at the end of the second season. They are biennials. Sugar beet is a good example of a biennial plant.
Many plants grow for more than two seasons. Most of our hay and pasture crops are perennials.

Seed starts to germinate only under certain conditions. The optimum temperature at which seeds germinate best varies with different kinds of seed. The optimum temperature for the germination of wheat, for instance, is about 270C. Cotton and corn germinate best at about 350C.
Seeds of all crops need enough air for germination as oxygen is necessary for certain chemical reactions which take place in the plant food in the seed.
These reactions take place only, when water is present. So, moisture is also necessary for the germination of seeds.
This, a seed does not germinate: 1) if the temperature is not proper, 2) if there is not enough moisture and air in the soil.
