Environment plays a major role in the development of a corn plant. Alternation of this habitat by a mechanical injury to the leaf tissue may alter the plant(s) growth pattern and in turn influence yield. The interruption of physiological and chemical processes during the growing season may be more harmful to the corn at one stage of its development than at another. The relative importance of leaf area as a determinant of yield must be considered to the extent that production varies or can be made to vary, as a result of the amount of photosynthetic area functioning on a plant for a specific period of the growing season.

The research reported in this thesis is a portion of a study on simulated hail damage to corn. The study was conducted under irrigated and non-irrigated environments. Corn yield losses varied depending on plant maturity and the defoliation treatment.
