North Dakota Fresh Market Potato Cultivar/Selection Trial Results for 2020
Potato cultivars or selections included in this report were selected from recently released cultivars, advancing selections with release potential (numbered lines progressing through the trial process), or cultivars that are new to the U.S. Standard potato cultivars used by growers served as checks. The agronomic data presented in Tables 1 and 2 were analyzed statistically. These analyses allow the reader to ascertain, at a predetermined level of confidence, if the differences observed among cultivars/selections are reliable, or if they might be due to error inherent in the experimental process.
Video presentations for the MN and ND Seed Reports for 2020 & PVY Spread

Cover Crops in Potatoes
Cover crops are plants grown between cash crops for the purpose of soil conservation. Cover crops reduce erosion from wind and water, and over time will improve and maintain soil organic matter and soil health. Additionally, cover crops may aid in pest management, increase soil biodiversity and carbon, reduce loss of nutrients, and can increase nutrient availability. In many cases, cover crops have been shown to increase yields of cash crops.
Potato Tuber Second Growth
Potato tubers are the result of the plant genetics and the environmental conditions in which they are grown. Potato varieties are selected carefully for tubers that have desirable appearance to maximize sales and reduce waste. However, some years can cause more environmental stress than others, resulting in tuber secondary growth. Secondary growth often manifests as heat sprouts, tuber chaining and tuber malformations. This physiological disorder decreases yield and quality of the tubers in the field.
