Abstract

\r\n The 2010 Soybean Management Verification Program (SoyMVP) consisted of 16 fields, totaling 379 acres and averaged 27 acres, across western Kentucky.  The fields were split giving seven direct comparisons between University of Kentucky recommendations and producer practices for soybean production.  Weekly scouting was conducted on all fields and recommendations made on the university portion of the field based on established thresholds and observations from agronomic research.   The purpose of these comparisons is to determine the applicability of university research to producer fields in Kentucky.  The 2010 growing season was quite varied across the SoyMVP fields, mainly being the lack of rainfall.  Planting was much earlier in 2010, with the earliest field planted in April and the latest the first week of June.  With the hot, dry conditions in August, harvest was much timelier than the 2009 season.  Weed pressure varied with the most common species being  Johnsongrass, crabgrass, pigweed, marestail, Eastern Black Nightshade, Virginia Copperleaf, and common lambsquarters.  Disease pressure was light, likely due to the hot, dry conditions.  Septoria leaf spot was seen at some level across most fields, with the higher incidence being at the locations that received more early-season rainfall.  Sudden Death Syndrome and Frogeye Leaf Spot were also present at very low levels.  The University of Kentucky recommendations averaged 44.3 bushels per acre, compared to 45.6 bushels per acre in those using producer practices.  Partial economic net returns per acre averaged $400.56 under University of Kentucky recommendations, compared to $397.38 using producer practices.
