Description
A technique is described for testing the response of cultivars to environmental factors using crossed, controlled gradients of mineral nutrient supply and simulated grazing. The usefulness of the technique was tested by growing the perennial ryegrass (Lolium perenne L.) cultivar Melle and the cocksfoot (Dactylis glomerata L.) cultivar Sylvan in isolation and in a complex mixture on the matrix. Contour maps of the frequency of tillers of the cultivars after 2 years' growth indicated that Melle is better suited to high fertility, heavily stocked sites. The technique may be useful as a compact, standardised method for cultivar testing.
