Studies on lucerne and lucerne-grass leys III. The effect of variety of lucerne and strain of grass

Abstract

1. An experiment comparing the growth and productivity of six varieties of lucerne representing a wide diversity of ecological conditions grown in association with S 37 Cocksfoot, S143 Cocksfoot and a commercial cocksfoot/timothy mixture is described and the results discussed.2. Variety of lucerne had a marked effect on establishment, persistence, recovery from defoliation, early spring growth, yield of total dried produce, proportion of lucerne in that produce and on yield of nitrogen.3. There was no evidence of differing degrees of compatibility of varieties of lucerne with the three strains of grass used.
