The ability of aphid-resistant lucerne cultivars to produce hay has been the subject of considerable debate. While small-plot cutting experiments satisfactorily evaluate the growth potential of cultivars, they are not able to evaluate their hay-making capabilities. An unreplicated investigation was conducted over a 4-year period to assess the production and hay quality of 8 cultivars. Sufficiently large areas were sown to each cultivar (0.22 ha) so that commercial equipment could be used for hay making and irrigation.
