Plant population, yield and water use of lucerne sown in autumn at four sowing rates.
(New Zealand Grassland Association., 2012)
Successful establishment of lucerne requires an adequate plant population to maximise yield and maintain stand persistence. The impact of autumn sowing lucerne at four sowing rates was investigated in a split-plot experiment ...
Natural resources for Canterbury agriculture
(New Zealand Grassland Association., 2010)
This plenary paper was presented as an introduction to the Canterbury region at the combined 2010 conference for the New Zealand Grassland Association, New Zealand Agronomy Society, Australian Agronomy Society and New ...
On-farm comparision of pasture production in relation to rainfall in central Otago
(New Zealand Grassland Association, 2010)
Dry matter (DM) yields of unimproved resident browntop-dominant pasture on three Central Otago dryland farms was <1.5 t /ha/year from 2008-2010. An intensive pasture renewal programme over >18 000 ha applied lime to increase ...
Perennial lupin establishment and yield when sown at five different rates at Glenmore Station, Lake Tekapo
The potential for perennial lupins to underpin grass/legume pastures was the subject of a research programme for merino farmers in areas where more conventional legumes struggle to thrive. A previously uncultivated pasture ...
Sheep performance on perennial lupins at Sawdon Station, Lake Tekapo
A three-year trial compared the performance of Merino ewes grazing on a perennial lupin pasture with a control flock run predominantly on lucerne pastures at Sawdon Station, Lake Tekapo.
Identification and effectiveness of rhizobial strains that nodulate Lupinus polyphyllus
(New Zealand Grassland Association, 2014)
Lupinus polyphyllus plants were heavily nodulated at 10 field sites sampled across the South Island. Twenty-two bacterial isolates from these nodules formed functional nodules on L. polyphyllus indicating that rhizobia ...
Productivity and composition of perennial lupin pastures in response to six growing rates, lime application and lupin type at Glenmore Station, Lake Tekapo
This study aims to identify the sowing rate necessary to produce lupin dominant and productive pastures in the New Zealand high country under low-moderate fertility, and a regime of late spring/early summer grazing. Blue ...
Emergence and control of gorse seedlings after the 2017 Port Hills fire
(New Zealand Grassland Association, 2018-11-13)
An experiment on the Port Hills, Canterbury, after mature gorse was burnt in the fires of February 2017, showed an oversown Italian ryegrass mix out-competed the rapidly germinating gorse seedlings. The shaded ...
Tolerance of newly sown cocksfoot-clover pastures to the herbicide imazethapyr
(New Zealand Grassland Association, 2017)
In New Zealand, subterranean clover is recommended as a companion legume in mixed swards, particularly in dryland cocksfoot-based pastures. However, establishment of cocksfoot is slower than perennial ryegrass and therefore ...
Soil pH, exchangeable aluminium and legume yield responses to deep-placed lime at Omarama Station
(New Zealand Grassland Association, 2018-11-17)
The passive moment of lime down the soil profile in dryland is slow so a machine was developed to directly inject lime into soil, and was tested it at Omarama Station. Pelleted lime was injected at simultaneous depths of ...
