      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.
    • Planting Date and Nitrogen Fertility Test on Lesquerella in 1993-94

      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.
