Sweet corn is one of the important horticultural crops of Iowa. With the exception of potatoes, the acreage planted and total value of the crop exceeds any other horticultural crop grown. It has been estimated that 95 percent of the sweet corn grown in the United States is used for canning, and no doubt this percentage would be about the same for Iowa.- The acreage grown in any one year in Iowa depends largely on the price the canner received for the canned product the previous year and the carry-over of canned sweet com from the previous year’s pack. Low prices and large stocks on hand one year cause curtailment in acreage and pack in the following year. In table 1 the acreage and yields are given for 1929-38 inclusive. Between 1920 and 1928, larger acreages were grown, and Iowa was often the leading state in the production of sweet com for commercial canning, but other states, more favorably situated with respect to markets and cooler weather during the harvesting period, have offered serious competition to the Iowa canners in late years.
