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 ...
The relationship between applied nitrogen, nitrogen concentration in herbage and seed yield in perennial ryegrass (Lolium perenne L.). I. Cv. Grasslands Nui at five sites around the globe
(New Zealand Seed Technology Institute on behalf of the International Herbage Seed Group, 1998)
Potential environmental problems following the use of applied nitrogen (N) in cropping have resulted in research on indicators which attempt to ensure that the amount of N applied matches the specific requirements for the ...
The performance of an efficient dairy system using a combination of nitrogen leaching mitigation strategies in a variable climate
(Elsevier, 2017-12-01)
An efficient dairy system, that implemented a combination of nitrogen (N) leaching mitigation strategies including lower N fertilizer input, standing cows off pasture for part of the day in autumn and winter (stand-off), ...
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. ...
Key features of the seed germination response to high temperatures
(John Wiley & Sons, Inc. on behalf of the New Phytologist Trust, 2012-10)
The responses of seed germination rates (GRs) and final germination percentages to soil temperature follow trends similar to those for many plant processes. There is an optimum temperature for seed germination (Tₒ), which ...
Fate of phosphorus applied to soil in pig slurry under cropping in southern Brazil
(Elsevier, 2018-07-01)
Strongly weathered soils (such as Oxisols), are inherently phosphorus (P) limiting and highly P-sorptive thus requiring continued P inputs for productive agriculture. Constant P inputs result in accumulation of soil P with ...
Potential profit gains from improving pasture productivity on New Zealand South Island high-country farms
(New Zealand Grassland Association, 2020-09-09)
Soil acidity combined with low levels of key nutrients on New Zealand hill-country farms are limiting factors for legume establishment/growth. However, legumes are a critical component of these farms as they provide nitrogen ...
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 ...
Assessing the ability of a stationary pasture height sensing device to estimate pasture growth and biomass
(New Zealand Grassland Association, 2019-11-04)
Good pasture management requires an accurate knowledge of whole-farm feedbase, yet most systems for measuring pasture growth are manually operated and time consuming. A newly developed pasture-measuring device enables ...
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 ...
