Effect of Precipitation and Long Term Nitrogen Fertilization on Nitrogen Uptake, Crude Protein Content and Yield of Bromegrass Forage1

W. L. Colville, Leon Chesnin, D. P. McGill

Open publisher page 28 citations

Abstract

Synopsis Average yields of forage were increased up to 380% with annual applications of nitrogen fertilizer. Applications of 120 pounds per acre of nitrogen resulted in the most efficient use of rainfall. Yields of forage were decreased at the higher levels of precipitation. Crude protein content of the forage was increased from 8.96 to 14.83% by adding 160 pounds per acre of N. Nitrogen recovery averaged between 54.7 to 73.9%.
