“…The grazing management required to retain Ariki rye grass in the mixture considerably reduced lucerne yield. Tama ryegrass has been successfully grown with lucerne, giving high yields of both species (Vartha & Fraser 1978), but the grass must be re-sown each autumn. O'Connor (1967) assessed the performance of prairie grass, timothy, cocksfoot, tall fescue, and ryegrass over-drilled into lucerne.…”

Mixtures of Matua prame grass and Maru phalaris with Saranac lucerne, grown on silt loam and cut infrequently, were compared with pure sowings of lucerne, Matua, Maru, and 'Grasslands Nui' ryegrass. Major nutrients returned in fertiliser mixture were equivalent to their content in the cut herbage. Of the mixtures, Matua yielded the most dry matter (DM) over 2 years (19000-224000 kglha/a, cf. 18500-19500 kglha/a for pure lucerne). Pure swards of Matua and Maru yielded more than Nui in all seasons, highest annual DM yields being 16800, 13 200, and 8600 kg/ha respectively. In the second year of measurement, grass contributed 40% of the total yield of the Matua mixture, the contribution being at a minimum of 17% in summer, increasing to 46% in autumn. The Matua mixture yielded 1300 kglha of grass DM in winter, whereas the Maru mixture yielded only 500 kglha. Spring yields of grass in the mixtures were similar, but in summer Matua yielded more than Maru.

“…An existing layout of lucerne-Tama ryegrass systems, as described by Vartha & Fraser (1978), was modified. This had been 2 replicates, each of six 0.3 ha paddocks (3 of pure lucerne, 2 of lucerne overdrilled with Tama ryegrass, and 1 of pure-sown Tama ryegrass) under either irrigated or dryland treatment.…”

AbstractTo improve the system of irrigated lucerne-Tama ryegrass for prime lamb production as outlined by Vartha & Fraser (1978), the period of hay feeding in winter needed to be reduced, as the required amount of hay could not be obtained within the system. So, pastures of Matua prairie grass and Maru phalaris (both with lucerne), and of Nui ryegrass with white clover, were added to the existing system.

To improve the system of irrigated lucerne-Tama ryegrass for prime lamb production as outlined by Vartha & Fraser (1978), the period of hay feeding in winter needed to be reduced, as the required amount of hay could not be obtained within the system. So, pastures of Matua prairie grass and Maru phalaris (both with lucerne), and of Nui ryegrass with white clover, were added to the existing system. Comparison between this extended system and lucerneTama was made over 3 years. For the lucerne-Tama system, hay produced was only 53% of that required for supplementary feeding in winter over 100 days. For the extended system, the perennial grasses enabled later grazing in autumn and earlier grazing in late winter with the result that winter feeding was required only over 62 days, and hay made in the system exceeded that required by 40%. Whereas the lucerne-Tama system, stocked at 25 ewesha and offered 12 t DM/ha per year, produced 470 kg meat/ha (with 88% of lambs exceeding 25 kg liveweight) the extended system, stocked at 22 ewes/ha and offered 12.15 t DM/ha per year, produced 390 kg meat/ha (with 91 % of lambs exceeding 25 kg liveweight). A final stocking rate/production result was not reached for the extended system, because insect attack of lucerne ended the experiment. Maru phalaris was successfully maintained with lucerne, but Matua prairie grass dominated lucerne in the first winter from sowing and subsequently became a mixture with unsown white clover. Keywords
