Both sorghum and soybeans are relatively new to most Iowa farmers. These crops have usually been late summer or supplementary crops. They may, in normal seasons, be planted from May to August; and since early-, medium-, ’and late-maturing varieties have been available, considerable variation in maturity has occurred at the time of the first killing frost. The result of the .indiscriminate planting of varieties at different periods of the summer and attempts to save seed irrespective of its condition in the fall has been low viability in many seed lots. Because of this condition a study was made of the effect of freezing temperatures on the subsequent viability of sorghum
