However, because B is a micronutrient and is therefore applied in very small quantities, even applica- tion of this nutrient can be difficult to achieve. Uneven application is a poten- tial problem because the range between deficient and toxic soil concentrations of B is very narrow. Aspire (Mosaic Co.; 0-0-58-0.5B) is a product devised to facil- itate even application of B by combining it in fertilizer granules with K, which, being required in high quantities, is eas- ier to distribute evenly. The objectives of this study were to: (1) evaluate Russet Burbank potato response to Aspire rela- tive to K without B (KCl), (2) evaluate the effectiveness of Aspire relative to KCl blended with supplementary granular B (Granubor), and (3) compare the effec- tiveness of a single pre-planting applica- tion of K to split pre-planting and emer- gence applications for both Aspire and KCl (without B). NDSU Potato Breeding Pro- gram, 2016 Dr. Susie Thompson, NDSU As in previous years, the North Dakota State University Potato Breeding Project is conducting field research and produc- ing certified seed at locations across North Dakota and western Minnesota. Research trials are grown at eight sites, and seed production in 2016 is taking place at one site. Our field research and seed production efforts are summarized here: Non-irrigated research sites include Crystal, Hoople and Grand Forks, North Dakota. The fresh market trials are con- ducted on the farm of Dave and Andy Moquist (O.C. Schultz), just north and east of Crystal. Trials include the North Central Regional Potato Variety Trial (NCRPVT) which was revamped a few years ago to focus on the fresh market sector. NDSU entries include ND6002- 1R, ND6961B-21PY, ND7818-1Y, ND7834-2P, ND7982-1R, and AND9933 1-2PintoY. The Fresh Trial includes 30 entries, 20 advancing selections and 10 industry standards. Skin and flesh col- ors vary from the standard red skinned/white fleshed, to purple skinned/yellow fleshed genotypes. The Preliminary Fresh Market Trial has 30 entries, 19 selections (primarily red skinned and white fleshed) compared to 11 industry standards. Lloyd, Steve and Jamie Oberg host the trials at Hoople, North Dakota, focused on chip process- ing. The non-irrigated Chip Trial includes 15 promising advancing selec- tions compared to nine chip industry r e C a t o s e n n i M t a t o P d e e S d e i fi i t rt s e o 4 - 3 7 7 - 8 1 2 u . n m . e t a t s . a d m . w w w , 6 5 9 4 o t a t o p / s s/ u o t a t o p / s s/ u . n m . e t a t s . a d m . w w w
