    • 1995-1996 Alfalfa Hay Yields from Eight Varieties Planted in February 1995 on the Colorado River Indian Tribes Reservation

      Rethwisch, Michael D.; Sakiestewa, Hipkoe; Ottman, Michael (College of Agriculture, University of Arizona (Tucson, AZ), 1996-10)
      Eight alfalfa varieties were evaluated for forage production during 1995 and the first half of 1996 following a Feb. 1995 planting. DK 189 has yielded the most tonnage thus far (104.8% of CUF 101), and all varieties have averaged over one ton of hay /acre/harvest.
    • 1995-1996 Alfalfa Yields of Five Varieties Planted Octobert 1994 on the Colorado River Indian Tribes Reservation

      Rethwisch, Michael D.; Baldwin, Bill; Baldwin, Joan; Leivas, Danny; Kruse, Michael; Ottman, Michael (College of Agriculture, University of Arizona (Tucson, AZ), 1996-10)
      Five alfalfa varieties (CUF 101, SW 14, SW8210, Pioneer 5888, and a grower selection primarily from CUF 101 and noted as Baldwin Select) were planted in October, 1994, into large plots (0.75 acres) to obtain actual field harvest data. Eight harvests were taken during 1995, and seven thus far in 1996. Varietal hay yields were very similar in 1995 until mid summer, when area soil temperatures reached above 100 °F at the four inch depth for a period of about 6 weeks. During the summer months of both years Baldwin Select significantly outyielded other varieties tested. Statistical differences in accumulated hay yields were noted beginning in August 1995 and have continued during 1996. Baldwin Select was the highest yielding variety during 1995 (103.3% of CUF 101), followed by CUF 101 and Pioneer 5888, both which averaged 1.16 tons /acre per harvest. SW 14 and SW 8210 yielded about 550 total lbs /acre less than CUF 101 during 1995. Baldwin Select has also been the highest yielding variety in 1996 thus far, yielding 113.6% of CUF 101. SW 8210 has been second (107.6% of CUF 101), followed by SW 14 (102.7% of CUF 101), with CUF 101 and Pioneer 5888 again being almost equal in yield at 1.14 tons /acre per harvest. For 1995- 1996 combined, Baldwin Select has yielded 108.2% of CUF 101, followed by SW8210 (101.9% of CUF 101). CUF 101, Pioneer 5888 and SW 14 are very similar in overall tonnage. Alfalfa varieties have been very similar in relative feed value when tested. Yellowing from Empoasca spp. leafhoppers was greatest during the 1995 -1996 winter on varieties with fall dormancy ratings of 9 or greater. Baldwin Select has yielded $121 /acre more hay than CUF 101, and SW8210 has yielded $44 /acre more hay than CUF 101 thus far in this trial.
    • 1995-1997 Alfalfa Yields of Five Varieties Planted October 1994 on the Colorado River Indian Tribes Reservation

      Rethwisch, Michael D.; Baldwin, Bill; Baldwin, John; Leivas, Danny; Kruse, Michael; Ottman, Michael (College of Agriculture, University of Arizona (Tucson, AZ), 1997-10)
      This report covers the first 2.5 years of production of five alfalfa varieties (CUF 101, SW 14, SW8210, Pioneer 5888, and a grower selection originating from CUF 101 and noted as Baldwin Select) that were planted in October, 1994, into large plots (0.75 acres) to obtain actual field harvest data. Data are reported from 22 harvests thus far in the study, including five from 1997. Varietal hay yields were very similar in 1995 until mid summer, when area soil temperatures reached above 100°F at the four inch depth for a period of about 6 weeks. During the summer months of 195 -1996 Baldwin Select had significantly higher yields than other varieties tested. Statistical differences in accumulated hay yields were noted beginning in August 1995 and have continued. during 1996. Baldwin Select has the highest yielding variety each year thus far, producing 8.8% more than CUF 101, worth $233 /acre. Alfalfa varieties have been very similar in relative feed value when tested. Yellowing from Empoasca spp. leafhoppers was greatest during the 1995 -1996 winter on varieties with fall dormancy ratings of 9 or greater. Weed infestations during late summer 1996 appear to be inversely correlated with fall dormancy, for which Baldwin Select significantly higher than CUF 101.

      This report contains the results of the 2000 National Cooperative Dry Bean Nursery Trials. This replicated, small plot trial contains thirty eight varieties of nine different bean classes. Buster, a pinto variety from Seminis Vegetable Seed Company, was the highest yielding variety in the study with a yield near 4000 pounds per acre. Yields, aerial biomass, harvest index, and 100 bean weights are reported for this study.

Bill-Z, a pinto variety, was the highest yielding variety in the Terry Brother=s trial with a yield over 3800 pounds per acre. K124467, a Flor de Mayo variety from Archer-Daniels-Midland, was the highest yielding variety in the Haas trial with a yield just under 2900 pounds per acre. Yields, aerial biomass, harvest index, and 100 bean weights are reported for all varieties in both studies.
    • 2012 Sorghum Silage Variety Trial at Maricopa

      Loper, Shawna; Ottman, Mike; Ottman, Michael J.; School of Plant Sciences / Maricopa Ag Center, University of Arizona (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2013-05)
      Nine varieties of silage sorghum and one pearl millet variety were tested at the Maricopa Agricultural Center in Maricopa, AZ. Information on silage sorghum yield and quality can be of use to the dairy industry and help growers choose the best varieties based on their needs. We found no significant differences among the varieties for ash, ADF, and NDF. We did find significant differences in yield with Silo 700 BMR having the highest yield with 31.62 tons/acre and GS125 having the lowest with 20.53 tons/acre. We also saw significant differences in crude protein with ExpGD having the highest (3.47%) and Silo 700 BMR (1.93%) being the lowest.
