Many growers are reluctant to adopt research based recommendations because of a perception that plot research is not applicable to whole farm situations. However, other growers adopt many of these practices successfully and can serve as a source of confidence for those that are more skeptical. The objectives of this project were to: 1) establish field demonstrations highlighting “model” potato (Solanum tuberosum) growers that exemplify best management practices (BMPs); 2) establish plots within each field to compare BMPs with a high input, maximum yield management (MYM) approach; and 3) enhance grower confidence regarding BMPs. Fourteen field trials were conducted in the Pacific Northwest over four years. Five replicates of BMP and MYM plots were established in a RCBD in each field. BMPs are documented in various Pacific Northwest publications and, essentially, entail applying inputs based on soil and plant sampling/scouting with a maximum economic yield approach. The MYM treatment resulted in 5-25% more fertilizer and pesticide application in each field based on a near zero tolerance for pest and nutrient problems. The MYM treatments resulted in significant yield increases in three fields and decreases in two fields, with an average increase of 1.4 Mg ha^-1 marketable yield. However, when factoring in cost of production, MYM treatment resulted in significant monetary increase in just one field and decreases in four fields, with an average decrease of $190 ha^-1. These demonstrations, with associated field days and grower meetings, have resulted in over 23,000 hectares of documented changes in grower practices towards BMPs. Many more undocumented hectares have likely been affected.
