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 ...
Progress in pasture plant physiology
(The New Zealand Society of Animal Production, 1967)
Some major achievements of pasture plant physiology are reviewed. Detailed study of growth patterns has provided an understanding of how grasses grow and how they persist in a grazed sward. Genetic variation for physiological ...
Understanding water losses from irrigated pastures on loess-derived hillslopes
(New Zealand Grassland Association, 2020-09-09)
Irrigation is likely to increase water losses from hillslopes, particularly on loess-derived soils with impeded drainage. This is important as irrigation of these soils in New Zealand is increasing. A field site was ...
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 ...
Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
(MDPI, 2016-06)
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
Urine patch area coverage of an intensively stocked dairy pasture
(International Union of Soil Science, 2010-08)
The urine patch of the grazing cow has been identified as the key source of N loss from pasture-based dairy
systems. Although critical to N modelling, quantitative data on the annual area coverage of urine patches in
pastures ...
Urine patch area coverage of an intensively stocked dairy pasture
(Lincoln University., 2010-08)
The objective of this study was to develop a new method to quantify seasonal and annual urine patch area coverage under an intensive dairy farming system.
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 ...
