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 ...
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 ...
Response of simple grass-white clover and multi-species pastures to gibberellic acid or nitrogen fertiliser in autumn
(NZ Grassland Association, 2013)
Herbage dry matter (DM) production, botanical composition and nutritive value of pastures were measured in response to the application of 24 g/ha gibberellic acid (GA; 60 g ProGibb®/ha) and 50 kg N/ha nitrogen fertiliser ...
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 ...
Plantain: It is not only the dietary content, but also how we graze it…
(New Zealand Society of Animal Production (Inc), 2018)
A mechanistic and dynamic model of a grazing ruminant, MINDY, was used to explore the effect of both the proportion dietary inclusion of plantain (PL) and its grazing management, compared with ryegrass (RG), on urinary N ...
Milk yield and urinary-nitrogen excretion of dairy cows grazing forb pasture mixtures designed to reduce nitrogen leaching
(Elsevier, 2018-03)
The effect of including a mixture of forbs in a standard perennial ryegrass-white clover pasture, with or without Italian ryegrass was investigated in a two-period grazing study comparing urinary nitrogen (N) excretion and ...
Metabolisable energy concentration in perennial ryegrass pastures: Multi-site analysis of effects of cultivar, nitrogen fertiliser and white clover content
(New Zealand Grassland Association, 2018-11-13)
To include metabolisable energy (ME) as a nutritive value factor for ryegrasses in the Forage Value Index (FVI) requires data for New Zealand cultivars on the effects of environmental and management ...
Whole-farm modelling using different grazing-management strategies with diverse pastures within an irrigated dairy-farm system
(New Zealand Society of Animal Production (Inc), 2018)
The objective of this study was to assess the effect of diverse pasture mixtures and grazing management on profitability of Canterbury dairy farms using a commercial modelling tool, Farmax Dairy Pro. Two years of pasture ...
In vitro fermentation characteristics of ryegrass-white clover sward containing different proportions of chicory
(New Zealand Society of Animal Production, 2017)
Chicory (Cichorum intybus) is a deep-rooted grazeable forage used to overcome production and nutritive value shortfalls of perennial ryegrass (Loliun perenne) and white clover (Trifolium repens) swards during summer drought ...
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 ...
