Performance of lucerne/grass mixtures on Atiamuri sand.

TL;DRAbstract

Dry matter production from lucerne/grass mixtures and lucerne alone was compared from 1974 to 1978. The grasses were 'Grasslands Apanui' cocks foot, Phalaris tuberosa, cv. 'Seedmaster', 'Grasslands Matua' prairie grass and 'Grasslands Roa' tall fescue. Where management aimed for maximum yield of lucerne in the warm season the inclusion of perennial grasses did not result in increased winter early spring production. Grasses tested did not form stable high-yielding combinations with lucerne. In the first year, lucerne/Matua outproduced lucerne alone by 6lllfo and other mixtures by at least 2lllfo while lucerne/Roa outyielded lucerne alone by 2711fo. There were no significant differences in total annual production after the first year. Lucerne/Roa outyielded lucerne alone by IOIIfo over the trial period. Lucerne/Roa had the highbt grass production and was almost weed free, but had the lowest lucerne production of all treatments. The inclusion of grasses, other than 'Roa' tall fescue, with
