The researchers are focused on current and future issues affecting potato growers in North Dakota and Minnesota. However, the findings of these research projects are often far greater that our region because the results are often used throughout the United States and other countries. We thank all the grower coop- erators for allowing research to be con- ducted on their farms, industry partners and the Northern Plains Potato Growers Association, Minnesota Area II Research and Promotion Council for their sup- port of the important research. Projects are funded by many sources, including the Northern Plains Potato Growers Association, Minnesota Area II Research and Promotion Council, through state and federal grants and private industry. If there are any questions or if there is something you feel needs to be studied, please let us know. We look forward to seeing you at the Northern Plains Potato Growers Association Field Day at Larimore, Inkster, and Hoople, North Dakota on Thursday, August 25th. Minnesota Area II Research and Promotion Council will hold a field day on July 19th in Becker, Minnesota at the Sand Plains Research Farm. More information on the field days can be found at potatoex- tension. University of Minnesota, Department of Soil, Water and Climate Dr. Sanjay Gupta, UMN In 2016 two studies have been initiated. The first study is being conducted to explore the biochemical changes related to reducing sugar accumulation and nitrogen use efficiency of tubers grown under varying nitrogen fertilizer regimes. The tubers are grown at the Sand Plain Research Farm in Becker. The second study is being conducted on the potato tubers grown in 2015 at three dif- ferent locations in Minnesota and North Dakota. The study is aimed to under- stand the physiological and biochemical changes in potato tubers during long term cold storage. The overall focus of these studies is to improve long term cold storage and quality of the new and existing cultivars. The objectives and brief descriptions of these studies are as follows: 1. Potato variety evaluation for nitrogen fertilization and cold-induced sweeten- ing resistance. Nitrogen (N) fertilizer is used routinely in potato cultivation to maximize yield. However, it also affects sugar, free amino 2016 Potato Field Research In N by Dr. Andy Robinson, NDSU/UMN Potato Extension Agronomist
