Abstract

The average production of wheat In Iowa for the five-year period 1911 to 1915, inclusive, was 14,834,950 bushels per year. In 1916 and 1917 the yield was 6,732,000 and 5,597,000 bushels. The state is therefore more than an entire crop behind at the present time, a serious shortage for one state to be responsible for when wheat may win or lose the war. The dry weather In the late summer and fall of 1917 made the sowing of winter wheat so difficult that little over 200,000 acres was sown, less than halt of a normal acreage. In many sections of the state severe winter conditions have made the production from this acreage decidedly doubtful. It the best of weather conditions prevail from now until· harvest we may not expect more than an average yield of 20.9 bu. per acre. This will give 4,226,068 bu. of winter wheat whereas Iowa normally produces over 10,000,000 bu.
