The effect of management and competition on the uptake of ³²phosphorus by ryegrass, meadow fescue and their natural hybrid.

Abstract

Festuca pratensis and Lolium perenne developed their roots less rapidly when grown with their triploid hybrid than when grown alone or together. The extent of their root systems was assessed by injecting ³²P at different soil depths in separate plots and estimating the activity recovered in the top growth.
