Small Grains Variety Evaluation at Yuma, 2007 Ottman, Michael J. Ottman, Michael J. Small grain varieties are evaluated each year by University of Arizona personnel. The purpose of these tests is to characterize varieties in terms of yield and other attributes. Variety performance varies greatly from year to year and several site-years are necessary to adequately characterize the yield potential of a variety. A summary of small grain variety trials conducted by the University of Arizona can be found online at http://ag.arizona.edu/pubs/crops/az1265.pdf.

Variety Mixtures for Reduced Input Barley, 2006 Ottman, Michael J. Ottman, Michael J. Variety mixtures may lessen competition among plants and reduce effects of stress particularly in environments where resources are limiting. Mixtures of four barley varieties were grown under low input conditions at the Maricopa Agricultural Center. The barley varieties seeded were Barcott, Solum, Solar, and an experimental low input line designated Entry 9. The highest yields were not obtained with mixtures in this experiment, but rather when the varieties were grown alone. Barcott and Entry 9 decreased yield when part of the mixture more than Solum or Solar. When Solum was grown in a mixture rather than alone, test weight and lodging were improved, but yield was decreased.

Testing Low Input Barley and Wheat Lines, 2005 Ottman, Michael J. Ottman, Michael J. Head rows of 4 experimental lines each of barley and wheat were grown at the Maricopa Agricultural Center. One barley and one wheat line were harvested and the seed retained as breeders seed. The barley line is significantly improved in yield, test weight, and lodging resistance compared to Solum. The wheat line does not represent a significant improvement over Yecora rojo, and may not be released.
