Dry matter production and water use of dryland cocksfoot/lupin and lucerne pastures in the third year after establishment
(Lincoln University, 2017-11-14)
Cocksfoot (Dactylis glomerata) is a preferred grass option for dryland pastures on high country farms in the South Island of New Zealand. However, increasing the productivity of cocksfoot based pastures with legumes is ...
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 ...
The development of a lucerne growth model : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 1992)
Lucerne (Medicago sativa) is a pasture plant which has been grown for over 2000 years, but despite this fact surprisingly little is known about it's regrowth. In the seventies the popularity of luceme was extremely high ...
Grazing and soil fertility effect on naturalized annual clover species in New Zealand high country
(Elsevier on behalf of the Society for Range Management, 2016-11)
With a view to increasing rangeland pasture legume abundance, the herbage biomass and seedling recruitment of four New Zealand naturalized annual clover species (haresfoot clover Trifolium arvense L., suckling clover T. ...
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 ...
Photogrammetry for assessment of pasture biomass
(New Zealand Grassland Association, 2019-11-04)
New tools are required to provide estimates of pasture biomass as current methods are time consuming and labour intensive. This proof-of-concept study tested the suitability of photogrammetry to estimate pasture height in ...
Grazing dairy cows with low milk urea nitrogen breeding values excrete less urinary urea nitrogen
(Elsevier, 2020-10-15)
There is an increasing pressure on temperate pastoral dairy production systems to reduce environmental impacts, coming from the inefficient use of N by cows in the form of excessive urinary N excretion and subsequent N ...
A study of New Zealand wheats. IV. Effects of extreme temperature at different stages of development
(Department of Scientific and Industrial Research, New Zealand, 1970-11)
At different stages of development single-tillered plants of Hilgendorf 61 wheat growing in a glasshouse were subjected for 3 hr to -1°, -2°, +38°, or +40.5° c in the dark, preceded by a 2-day conditioning period. Applied ...
Effectiveness of strategies used to establish plantain in existing pastures
(New Zealand Grassland Association (NZGA), 2019-11-04)
In recent years plantain (Plantago lanceolata) has emerged as a potential forage for reducing nitrogen losses from dairy farm systems. However, achieving sufficient proportions of plantain in pastures to help meet target ...
