Net photosynthesis rate and chlorophyll content of Caucasian and white clover leaves under different temperature regimes
(Lincoln University. Faculty of Agriculture and Life Sciences., 2005)
Caucasian or kura clover (Trifolium ambiguum) was more productive than white clover (Trifolium repens)in New Zealand pastures. Examining the physiological basis for this difference can provide greater insight into the ...
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 ...
How does defoliation management impact on yield, canopy forming processes and light interception of lucerne (Medicago sativa L.) crops?
The frequency of defoliation is the major management tool that modulates shoot yield and the accumulation of C and N root reserves in lucerne crops. A fully irrigated, two year old lucerne (Medicago sativa L.) crop was ...
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 ...
Calculating “Hydrothermal time” to quantify seed germination of tall fescue
The objective of this study was to quantify the combined effects of temperature and moisture on germination of tall fescue seed. Seeds were incubated for up to 50 days at a range of constant temperatures (5-35ºC) and ...
Sampling methods for clover species in grazed pastures to diagnose mineral deficiencies
(New Zealand Grassland Association, 2019-11-04)
Diagnosis of clover nutrient status is important for legume-based pasture systems. The protocols for sample collection and setting of nutrient guidelines are ill-defined. This research quantified how nutrient concentrations ...
