<br />Mobile rain shelters were used to protect corn (Zea Mavs L.) from all natural rainfall during the
<br />summers of 1987, 1988, 1989 while providing water to the crop through an overhead sprinkler system
<br />mounted in the rain shelters. Water was applied to the crop to simulate typical dry, normal, and wet
<br />summers in cenltrallllinois. Final yields were measw~ed at harvest along with the various yield
<br />components (number of kemel rows/ear, number of kemels/row, total number of kemels/ear, kemel
<br />mass) that determine final yield. Yields were increased in each of the typical summers by increased
<br />rainfall. The greatest benefit of the increased rainfall was realized at pollination and the two weeks
<br />following pollination as expressed by an increase in the number of kemels/fertile ear. Neither the
<br />number of kernel TOws/fertile ear nor the fmal mass of the kemels were affected by the rainfall
<br />treatments. In addition to larger fertile ears, some yic~ld increase was realized by a reduction in the
<br />number of barren plants in the plant population under higher rainfall treatments.
