1. Biomass and Nitrogen Partitioning of the Modern Russet Varieties of Potatoes Under Nitrogen Stressed and Optimum Conditions

Wisconsin is the third largest producers of potatoes in the USA. Nitrogen (N) is the most limiting nutrient in the development of crop biomass and yield. N uptake and partitioning in potato can be different based on the varieties and nutrient availability. These differences can result in the wide variations in yield accumulation and nitrogen use efficiencies. However, there is a lack of quantitative understanding of the in-season N uptake and demand and biomass partitioning of the different varieties... A. Rawal, M.D. Ruark, R.A. Lankau, J. Ross
