2007 Dry Bean Performance Evaluation

Mike Moore, Wyoming Seed Certification Service; Mike Killen, Powell Research and Extension Center, Randy Violet, Powell Research and Extension Center

In 2006, Wyoming ranked ninth nationally in dry bean (Phaseolus vulgaris L.) production, and fifth in the nation in the production of pinto beans. In the same year, Wyoming growers produced 510,000 hundred-weight of pinto beans on 24,000 harvested acres, averaging 21.3 hundred-weight per acre.

The University of Wyoming Seed Certification Service coordinates the dry bean variety performance evaluation at this location in a continuous and on-going program. In cooperation with the National Cooperative Dry Bean Nursery, a wide range of germplasm is evaluated each year, including promising new lines and newly released varieties, assisting producers in selecting varieties best suited for Wyoming soils and climate. Public and private (proprietary) varieties are tested.

Materials and Methods

The experiment was located at the University of Wyoming Research and Extension Center in Powell, Wyoming. The soil, a Garland clay loam, (fine, mixed, mesic: Typic Haplarid), was prepared by roller harrow and leveled in the spring. A preplant incorporated chemical treatment of 2 pints Sonalan and 14 ounces Outlook was applied, and the plots received 60 units of N, 50 units of P, and 10 units of Zn. The plot area was irrigated and cultivated prior to planting on May 30^th in plots 5.5 feet wide by 20 feet long. The experimental design was a randomized block with 4 replications. IH 185 planter units with cone attachments were used, set on 22-inch row spacing. Cultivation controlled weed escapes during the growing season. Furrow irrigation was applied on May 11^th (preplant), June 30^th, July 9^th, July 24^th, August 2^nd, August 13^th, and August 24^th. Visual estimates for days to 50 percent bloom (50 percent of plants at second bloom) and days to maturity (50 percent of the plants with one buckskin pod) were made. Subplots of one row by 18 feet were pulled by hand, and plots were threshed with a Wintersteiger small plot combine. The seed was then hand screened over a ¹⁰/₆₄ x inch slotted screen and hand picked to remove dirt clods and seed mixtures. Samples were then weighed for clean seed yield per plot and seeds per pound.

Results and Discussion

Stand establishment was very good. Spring and summer were warm and dry, resulting in excellent plant vigor and yield potential. Yields across entries averaged 3,984 lbs. per acre, and ranged from 2,399 pounds per acre for BD1004 cranberry bean to 5,003 pounds per acre for PT 7-1 pinto bean.

This nursery is possible only with significant assistance from the staff at the Powell Research and Extension Center. R & E Center staff manage the plots, take growing season notes, and harvest the plots, and their efforts are greatly appreciated.
