2 Trial Highlights The 2015 Field Pea Trials consisted of 5 sites (Bison, Blunt, Dakota Lakes, Selby and Wall) across the central and western portions of South Dakota. In total, 24 varieties (16 yellow and 8 green Table 1) were tested. Across all sites, the trial average was 43 bu/ac with a range of bu/ac. The highest yielding site was Blunt with a trial average of 60 bu/ac and a range of bu/ac. This range (25 bu/ac) highlights the fact that variety selection is incredibly important. Weather played a significant role in this year s growing season. Planting occurred in extremely dry conditions for most of the sites. Dry conditions led to delayed and uneven germination. As the spring progressed, conditions shifted to generally wet conditions. Combined with rising temperatures, powdery mildew was seen at Blunt and Selby. Hail damage was recorded at the Dakota Lakes site, which may have affected yields somewhat. Table 1.

3 Cultural Practices Bison, Dakota Lakes, Blunt and Wall were planted with a John Deere 750 No-Till Drill. The seeding rate was 350,000 plants/ac (adjusted for germination percentage) and the seed was treated with a granular inoculant. Planting and harvest dates and previous crop are listed in Table 2.

Siedel (Bison), R. Leesman (Blunt), D. Beck (Dakota Lakes), M. Stiegelmeier (Selby) and D. Patterson (Wall). Additionally, we are grateful to all the SDSU staff that assisted with the trials including M. Swan, C. Ellis and S. Hawkes. Page 3
