Decreasing farmland and increasing demand for nutrient-dense food highlight a need for more efficient growing practices that increase grower revenue and reduce costs associated with potato farming. Attempting to use best management practices developed for Russet Burbank to optimize growth for new varieties reduces efficiency and limits grower returns. As such, best management practices should be established for new varieties. Clearwater russet, a variety released from the Pacific Northwest Variety Development Program in 2008 and accepted by McDonalds in 2016, has substantially increased in acreage in the Pacific Northwest (PNW) due to desirable processing characteristics. Potato seed size plays an important role in emergence and plant establishment. Moreover, seed size may affect economic returns by altering seed costs. Research was initiated in 2021 at Aberdeen, ID to identify ideal seed sizes and to investigate differences resulting from planting cut versus whole seed tubers for Clearwater Russet that maximize financial returns through improved yields and cost reduction. Initial data indicate trends toward varieties reacting differently when seed sizes of 1 to 3.5 ounces are planted. Data for Clearwater Russet tends to indicate a seed size of 2.5 ounces produces better yields and cost-adjusted gross returns compared to larger and smaller seed sizes. Data also indicates a trend toward increased yields and cost-adjusted gross returns for cut seed pieces versus whole seed pieces. Additionally, tubers tended to fall into larger size categories when cut seed was used compared to whole seed. This data is derived from a single year and therefore cannot be completely conclusive, although some patterns appear to be emerging.
