This report contains the results of the 2001 National Cooperative Dry Bean Nursery Trials. This replicated, small plot trial contains forty eight varieties of ten different bean classes. Buster, a pinto variety from Seminis Vegetable Seed Company was the highest yielding variety in the study for the third year in a row, with a yield above 3500 pounds per acre. Yields, aerial biomass, harvest index, and 100 bean weights are reported in this study.

This report contains the results of the 2003 National Cooperative Dry Bean Nursery Trials grown at two different sites in southeastern Arizona. These replicated, small plot trials contained twenty-eight varieties from ten different classes of beans. 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.

This report contains the results of the 1999 National Cooperative Dry Bean Nursery Trials. This replicated, small plot trial contains thirty nine varieties of ten different classes of beans. Buster, a pinto variety was the highest yielding variety in the study with a yield over 3700 pounds per acre. Yields, percent moisture, aerial biomass, harvest index, seeds per pound, and plant populations are reported for this study.

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.

This report contains the results of the 2002 National Cooperative Dry Bean Nursery Trials. This replicated, small plot trial contains thirty-one varieties of eleven different bean classes. USPT-73, a pinto variety from WSU/USDA-ARS Prosser was the highest yielding variety in the study with a yield above 3600 pounds per acre. Yields, aerial biomass, harvest index, and 100 bean weights are reported in this study.

Results of the 1994 National Cooperative Dry Bean Nursery Trials are reported in this report Thirty two varieties of eight different classes of beans were included in this replicated, small plot trial Bill-Z, the leading pinto bean variety in the area, was the highest yielding variety with a yield over 4200 pounds per acre. Chase, a pinto variety recently developed with strong rust tolerance, yielded over 4000 pounds per acre. Yields, seed per pound, days to bloom, seed fall duration and yield per day of seed fill are reported in this paper.

Lesquerella is a potential crop plant that produces seeds containing hydroxy fatty acids similar to those in castor beans. An important step in the commercialization of this plant for Arizona farms is the development of an efficient agronomic production system. Research on planting dates and nitrogen fertility was conducted at the Maricopa Agricultural Center in the 1991-92, 1992-93, and 1993-94 seasons. Results of the Planting date experiments indicate that early fall planting dates are superior to late fall planting dates in terms of seed yield February plantings appear to be too late for central Arizona production. In all years, lesquerella responded to nitrogen (N) fertilizer. In the 1993-94 test, an application of 54 lbs. N/acre gave a higher seed yield than when no N was applied and the same yield as 108 lbs. N/acre. Additional tests are being conducted to determine optimum timing for N fertilizer applications.
