Effect of Nitrogen and Potassium on the Yield and Chemical Composition of Alfalfa, Bromegrass, Orchardgrass, and Timothy Grown as Pure Species¹

Synopsis: Yield response to additional K for grass increased up to a tissue content of 2% and levelled off between 2 and 3%. Percent protein, nonprotein and nitrate N in the forage increased with N fertilization but decreased with K fertilization. Significant interaction effects showed that adequate K (50 pounds/acre) insured a balanced N metabolism in forages heavily fertilized (100 to 200 pounds/acre) with N.
