Description
In France, red clover is often grown in association with a grass in order, if not to increase the yield of forage, at least to improve its quality by having a larger protein content in the harvested product. Among the grass species associated to red clover, Italian ryegrass, too aggressive a competitor, is replaced more and more by hybrid ryegrass. The aims of the present work were the following
1% to obtain quantitative references on the behaviour o[ hybrid ryegrass/red clover associations in four contrasting regions of France ;
2% to check that the presence of clover, through the transfer of fixed nitrogen, does increase the production of ryegrass, and thus brings about the saving of some nitrogen fertilizer
3% accessorily to spot possible differences among cultivars of red clover as to the ability to form efficient and productive associations with hybrid ryegrass

Red Clover Hybrid Ryegrass Associations Results Obtained from 1984 to 1987 in Four French Regions
