Advanced cultivars of small grains were compared with commercially available hybrids in on farm trials. Twenty three, 18 and 29 varieties of wheat, barley and durum were tested in a random complete block layout. All had at least one hybrid that yielded 6000 lb./ac or better. Wheat and barley had one hybrid each (Brooks, 6395 lb./ac; Max, 6356 lb./ac respectively) that had yields in excess of 6000 lb. /ac. Durum, had many superior hybrids that gave excellent yields (hybrids: Aconchi, 6772 lb./ac, V8001(WPB) 6320 lb./ac, V8013 (WPB) 6035 lb./ac, D1268 (FMC) 6023 lb./ac, V8010 (WPB), 5952 lb./ac, D8869, 5881 lb./ac). These yields were obtained with 42 water and 260 lb./ac NH₃ applied.

Thirteen varieties of wheat were tested at the Safford Agricultural Center in 1994. An experimental variety, BR6053 was the highest yielding variety in the trial with a yield of 4453 pounds per acre.

Eight varieties of durum wheat, seven varieties of barley and four varieties of bread/feed wheat were grown in a replicated small plot study on the Safford Agricultural Center in the 1995 growing season. The results of this study are reported in this paper.

An irrigation study on barley was made to determine the economical consequences of irrigating the crop when an irrigation scheduling program called for an irrigation compared to waiting 3 to 6 days for a water turn, from the ditch. The plots irrigated when the soil moisture depletion level reached 40% produced the highest yield. Yields were decreased 700 and 1000 pounds respectively for waiting 3-4 days and 6-7 days, respectively. The economics of using the pump are discussed and a chart is given to help determine a break - even point.
