Trials were conducted to determine southern pea performance in two different production environments in Oklahoma. Plots consisted of one row 20 feet long with 30 or 36 inches between rows. Seed were spaced 10 seed per foot and were inoculated with Rhizobium at planting. The trials were seeded on 15 June 2004 at Bixby, Okla. (elevation836), and on 16 June 2004 at Goodwell, Okla. (elevation 3293). Trials included at least three replications in a RBD for the 15 cultivar/breeding lines. Plots received a PRE application of Dual Magnum at 1.0 lb ai/acre tank-mixed with Pursuit at 0.063 lb a.i./acre. Supplemental water was applied with overhead irrigation. Maturity before harvest was rated as percentage of dry pods. TX158BEgc, LA 96-4, and US-1076 had the highest percentage of dry pods at both Bixby and Goodwell for blackeye, cream, and pinkeye types, respectively. Yields are given as imbibed lb/acre. Peas with consistent yields at both Bixby and Goodwell included blackeye types AR 00-178 with yields of 2,558 and 4,738 lb/acre, respectively, and ARK Blackeye #1, which had yields of 2,605 and 4,406 lb/acre, respectively. The highest yielding cream type at Bixby was LA 96-4, at Goodwell it was Early Acre, these had yields of 2,346, and 3,983 lb/acre, respectively. The highest yielding pinkeye types included AR 96-854 at Bixby and AR 01-1293 at Goodwell which yielded 3,593 and 4,366 lb/acre, respectively. LA 96-18 had yields of 2,886 and 2,853 lb/acre at Bixby and Goodwell, respectively, and was the most consistent yielding pinkeye for both sites.
