The sugar beet crop during the last few years has come to be one of the most important sources of income for farmers in many sections of the country. The fact that the sale for the crop is certain at a price that is known in advance, in addition to the high type of farming that usually accompanies sugar beet raising, makes it probable that the sugar beet area will be considerably extended during the next few years.
