Forage Production of Four Crops Grown Under Two Different Production Cultures, 1990(College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)Forage trials of four crops grown under high-input and low-input production cultures were performed at the Maricopa Agricultural Center. Six varieties of each crop were grown to evaluate yield potential under both production cultures. Only a preplant irrigation was applied to the low-input culture, but up to four additional irrigations were applied to the high-input culture. No fertilizer application was given to low-input, but a total of 135#N/A and 75#P₂O₅/A was applied to the full production culture. Barley, durum, and wheat cultivars developed for grain yield under a low-input production culture were tested for forage production under both high- and low-input practices. No advantage in forage production was observed by using the following varieties in a low-input production culture: Stampede oats, Westford barley, Mexicali durum, and 911 wheat produced the highest yields in each of the four crops. Yields were greater from crops grown under a high-input culture: Stampede oats, Harlan II barley, Aldura durum, and 911 wheat were highest yielding varieties in each crop.
Oat Variety Grain and Forage Yield Trials at the Maricopa Agricultural Center, 1990(College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)Twelve oat varieties (9 hulled and 3 hull-less) were yield tested for both forage and grain production at the Maricopa Agricultural Center during the '89-90 growing season. Highest forage producing varieties were generally later maturing - Cayuse and Stampede; while lower yields were produced by early maturing varieties - Montezuma and Palestine. Highest grain yields were produced by Swan and FMC400.
Small Grain Variety Comparisons at the Maricopa Agricultural Center, 1990(College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)Yield trials were conducted at the Maricopa Agricultural Center during the '89 -90 growing season. Barley, durum and wheat varieties as well as experimental lines from various seed companies were tested for yield performance. Gustoe and two experimental lines, 7024 and PHS84-11, were the highest yielding barley entries. Aldura, Turbo and Aldente were the top yielding durum varieties. 911, Probred and BR5738-1 were the top yielding wheat cultivars.
