SIMULATED hail damage experiments are conducted privJmarily to provide information (1) to ascertain ultimate damage to a growing crop and (2) to understand better the physiological processes of plant recovery. For the most part, past investigations were made with an attempt to imitate actual hail injury. Since hail causes many kinds and degrees of damage, considerable difficulty has been encountered in translating resultant data into information useful in determining the extent of injury. Past investigations involving mutilation to soybeans have indicated that the component factors contributing to the ultimate damage should be considered relative to both their separate and combined effects at various stages of growth. Certain components contributing to simulated hail injury on soybeans have been reported in research bulletins by Camery and Weber 3 and Kalton, et al. These components were defoliation percentages, stand reductions, breakages, and shattering and were inflicted at various stages of growth.
