Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
Maximising the subterranean clover content on a summer-dry Wairarapa hill-country farm through grazing management
(New Zealand Grassland Association, 2019-11-04)
Tokaroa Farm is a 608-ha sheep and beef farm, in the Wairarapa. Paddock slopes range from flat to steep (>25°) with a predominance of gentler north facing slopes and steeper south facing slopes. Annual rainfall is 810 mm ...
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 ...
The influence of spring grazing management on yield and water use of rainfed lucerne
(New Zealand Grasslands Association, 2019-11-04)
Flexible spring grazing management can increase the use of lucerne on farms. However, the negative impacts of set stocking on the survival of plants usually preclude its use. In this experiment, crops of ‘Stamina 5’ lucerne ...
Seed development of arrowleaf, balansa, gland and Persian clover
(New Zealand Grassland Association, 2015)
The development process from floral bud formation to seed maturity of four top flowering annual clovers was quantified from a field experiment across 10 sowing dates at Lincoln University, Canterbury, New Zealand.
For each ...
Productivity and composition of perennial lupin pastures in response to six growing rates, lime application and lupin type at Glenmore Station, Lake Tekapo
(NZGA, 2016)
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 ...
Lucerne dry matter and N-fixation, when sown with or without lime and inoculant
(New Zealand Grassland Association, 2015-11)
This paper quantifies the effect of inoculation and lime on lucerne growth and nitrogen fixation over the establishment and following season. The field experiment at Ashley Dene, in Canterbury, had an initial soil pH of ...
Calculating “Hydrothermal time” to quantify seed germination of tall fescue
(NZGA, 2016)
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 ...
Yield and composition of lucerne stands in Central Otago after different winter grazing and weed control treatments
The effect of grazing date and time of spraying with a glyphosate/atrazine herbicide combination on a three year-old lucerne stand was studied on-farm in Central Otago. Total annual dry matter (DM) yield was highest in the ...
Premature mammary development in ewe lambs exposed to an oestrogenic lucerne pasture
(NZ Grassland Association, 2016)
A report of mammary development in 6-month-old ewe lambs grazing lucerne on a commercial farm in North Otago provided an opportunity to investigate the possibility to use this as a tool to detect oestrogenic
lucerne pastures. ...
