Objective:

To evaluate pea cultivars for yield and agronomic performance.

Results:

Yellow pea yields averaged 83.8 bu/A (Table 2), ranging from 74.0 bu /A for CDC Leroy to 92.8 bu/A for Salamanca. Despite the range in yields there were no statistical differences among cultivars evaluated. Average calendar day to 50% flower was 179 days (June 28) with Navarro being the earliest at 174 days (June 23) to 182 days (August 1) for Spider. Height at pod-fill averaged 47.3 inches and ranged from 43.6 inches for Bridger to 51.1 inches for Earlystar. Universal was the first to reach physiological maturity at 213 days (August 1). Vine length and canopy height at physiological maturity averaged 43.5 inches and 20.5 inches respectively. Test weight averaged 64.3 lb/bu.

Green pea yield averaged 74.9 bu/A. The highest yielding cultivar was Daytona at 90.2 bu/A (Table 3). Average Julian calendar day to 50% flower was 179 (June 28) and ranged 175 to 181 Julian calendar days. Physiological maturity was observed at an average of 214 Julian days (August 2) and ranged from 212 to 216 days. Height at pod-fill averaged 43.9 inches and ranged from 40.0 inches for Arcadia to 48.4 inches for Daytona. Test weight averaged 62.7 lb/bu and ranged from 61.3 lb/bu for Aragorn to 64.2lb/bu Greenwood. No significant difference was observed in vine length and height at physiological maturity.

Summary:

Pea yields were slightly higher than in 2013 most likely due to the favorable growing season; timely spring rains, low insect, disease and weed pressures, and no hail during pod and seed development.
