Alfalfa is the most important perennial forage crop in Minnesota. There is a critical need for information about the potassium (K) fertilization for intensively managed modern alfalfa varieties. This project determined the effects of K fertilizer application on the forage yield and forage quality of alfalfa varieties with improved disease resistance and yield potential. Potassium’s role in long-term alfalfa stand persistence was explored, and K uptake of alfalfa was determined.
