2007 Late Harvest Regional Trial LRT Process Value Economic Potential The gross return in U.S. dollars per acre for each trial entry was calculated using a late-harvest mock processing contract. Process-market values are based on criteria and assumptions similar to that used by WA potato processors (see “Process Market Value-Methods” in front of book). Production costs per acre were not applied. Contract assumptions are listed at front of book under “Process Market Value - Methods.” Figure 1, below, shows the gross value of all trial entries when compared against a standard reference variety. Figure 1. Difference in gross return per acre (Process Market) from Ranger Russet calculated by subtracting the gross return of Ranger Russet ($3050) from the gross return of the particular entry. Entries with the white-colored bars were REJECTED (under the mock contract parameters) due to low specific gravity. 2007 Potato Cultivar Evaluations 91 WSU Potato Research Group
