Abstract
Eighty commercial hybrid grain sorghums were evaluated for field grain production and other agronomic characteristics in a full season test with limited irrigation at the University of Arizona Marana Agricultural Center in 1983. This test was planted in moisture on May 20, 1983, in single row 40-inch beds. Sixty lbs/acre of N was applied in the irrigation water. Total irrigation water applied was 17 inches. There was record-breaking rainfall of 16.92 inches for a total water application of 33.92 inches. This test was under about 1 foot of slow-running flood waters for about 48 hours on October 2 and 3, 1983. Much of the rainfall occurred in August, September, and October after the time of maximum influence on grain yield. The entries were combineharvested on December 1 and 8, 1983.
