Nitrogen-Potassium Utilization by Three Pasture Grasses1
- Robert W. Duell2
Orchardgrass yields were reduced more by the inadequacy of applications of NH4NO3 only, than were tall fescue or Kentucky bluegrass. Percentage of K in plant tissue decreased where NH4NO3 was the only fertilizer applied. Orchardgrass showed the greatest and Kentucky bluegrass the least response to differences in K. In P content and responsiveness to P availability, the species ranked: orchardgrass>tall fescue>Kentucky bluegrass. Plots receiving only NH4NO3 had higher percentages of crude protein. Tail fescue generally had the lowest percentage of crude protein.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
