Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser
on gorse establishment was monitored over 23 months in land converted
from pine forest to a dryland sheep pasture. There were fewer gorse plants
in ...
Influence of environmental factors on the abundance of naturalised annual clovers in the South Island hill and high country
(New Zealand Grassland Association., 2010)
The abundance of four naturalised annual clovers
(striated, cluster, suckling, haresfoot) and two
sown clovers (subterranean and white clover) was
investigated in relation to topographical, soil fertility
and management ...
There is no relationship between plasma amino acid concentration and urinary nitrogen concentration in heifers fed plantain or ryegrass
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-04-20)
The objective of this study was to investigate the relationship between plasma amino acid (AA) concentration and urinary nitrogen (N) concentration of dairy heifers offered cut plantain or perennial ryegrass-white clover ...
Implications of grass-clover interactions in dairy pastures for forage indexing systems. 4. Canterbury
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018)
This paper describes how the core treatments in the national experimental design (all combinations of with/without clover and high/low nitrogen (N)) were implemented at an irrigated Canterbury site and monitored for three ...
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. ...
Effects of MaxP™ endophyte in tall fescue on pasture production and sheep grazing preference, in a dryland environment
(New Zealand Grassland Association, 2007)
Pasture growth, botanical composition and sheep grazing preference were measured over 20 months in tall fescue (cultivar Advance), without endophyte (Nil) or infected with AR542 (MaxPTM) endophyte, and clover pastures sown ...
Assessment of the application of gibberellins to increase productivity and reduce nitrous oxide emissions in grazed grassland
(Elsevier, 2015-09-01)
© 2015 Elsevier B.V. Emissions of nitrous oxide from grassland systems are attributable largely to the use of nitrogen fertilisers and the excreta deposited by grazing animals. There is increasing interest in using ...
Development of a forage evaluation system for perennial ryegrass cultivar and endophyte combinations in New Zealand dairy systems
(New South Wales Department of Primary Industry, 2013-09)
An economic index for perennial ryegrass (Lolium perenne L.) cultivars is a relatively new concept, although recently introduced in Ireland (McEvoy et al. 2011). By contrast, in dairy cattle breeding, the concept of an ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
Can a winter-sown catch crop reduce nitrate leaching losses after winter forage grazing?
(Fertilizer and Lime Research Centre, 2016)
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined ...
