Pinto Bean Variety Demonstration in Bonita, Graham County, 1990 Clark, L. J.; Marcarian, V.; Cluff, R. E. Ottman, Michael Nine pinto bean varieties were tested in the Bonita area of Graham county as a follow up to the tests the previous two years. The top yield in 1990 was nearly 1700 pounds per acre compared with 3200 to 3000 for 1989 and 1988, respectively. Late planting early frost and bean rust all figured into the reduced yields. Additionally, a replicated, small plot test was planted to eleven different species of beans as diverse as garbanzo, lima and kidneys. Yield results and comments on these beans adaptability to the area are included in this report.

Revegetation of Retired Farmland: Evaluation of Six Range Grasses under Three Irrigation Regimes Thacker, Gary W.; Cox, Jerry R. Ottman, Michael In July of 1986, we seeded buffelgrass, klein grass, "Catalina" lovegrass, "Cochise" lovegrass, bottlebrush, and sideoats grama grass on retired farmland in the Avra Valley west of Tucson. We seeded these grasses under three irrigation regimes: no establishment irrigation, two establishment irrigations, and four establishment irrigations. In measurements of the standing forage in 1987 -90, four establishment irrigations significantly increased the standing forage over the unirrigated treatments. However, the two irrigation treatment was not significantly different from either four irrigations or no irrigations. Buffelgrass, klein grass, and the lovegrasses appear to be promising species for vegetative cover for this site. We have also measured significant increases in the standing forage over the last four years.

Revegetation of Retired Farmland: Response of Range Grasses to Establishment Irrigations and Microcatchment Water Harvesting Thacker, Gary W.; Cox, Jerry R. Ottman, Michael In July 1987, we began an experiment to evaluate the effects of water harvesting and establishment irrigations on range grasses on retired farmland In the first two years since establishment, we measured significantly higher forage production where we applied establishment irrigations. After three years, the difference from irrigation was no longer significant. We have not detected any significant differences in forage production due to water harvesting treatments.

Grain Sorghum Variety Trials in Greenlee County, 1990 Clark, Lee J. Ottman, Michael Seven grain sorghum hybrids were compared in replicated tests where full season hybrids were compared against each other and with mid full season hybrids. The full season hybrids yielded from 600 to greater than 1000 pounds per acre more than the mid full season hybrids. DeKalb 69 was the highest yielding hybrid with a yield of 8784 lbs/ac, but all three full season hybrids yielded greater than 4 tons per acre.
