In many parts of the world, where "dry land farming" is practiced, there is only one crop grown per year because there is only water for the plants in winter when it rains. On the other hand, rice growers (rice is a grain like wheat, barley, rye etc.) in the tropics sometimes get three crops per year. It is also a good idea to only grow one crop per year so as not to overwork the land and drain all of the goodness out of the soil. Many farmers grow a crop of legumes (not a grain) to enrich the soil with nitrogen, then grow grain the following year and finally leave the land for a year without crops or simply graze it. It all depends on where you live in the world and what grain is being grown as to how many crops are grown each year.
