Crossing the species barrier: investigating vertical transmission of a fungal endophyte from tall fescue within a novel ryegrass association
(Lincoln University, 2017-02-28)
Many Poaceae grasses form a symbiosis with Epichloë fungal endophytes. Initially a serious problem in agriculture due to their production of alkaloids toxic to livestock, endophyte strains were identified that were less ...
Interactions between pasture species and management and their implications for evaluating perennial ryegrass (Lolium perenne L.) cultivars in dairy systems
(Lincoln University, 2016-07-19)
An index to rank perennial ryegrass cultivars based on their relative economic benefit to pasture-based dairy systems, has been developed in New Zealand (Chapman et al., 2016; DairyNZ) in recent years. Performance values ...
Novel markers for drought resistance in white clover
(Lincoln University, 2011)
Introduction. White clover (Trifolium repens L.) is an out-crossing allotetraploid (2n=4x=32) that acts like a diploid, also called amphidiploid. White clover is a forage crop with a high level of genetic heterogeneity, ...
New Zealand maize grain production - where is the future?
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2012)
The Maize grain industry in New Zealand has remained relatively static over the last 5 years in both the human and animal food sectors. The domestic market in New Zealand presents limited opportunities to expand in both ...
Growth and development of different lucerne cultivars
(Lincoln University, 2016-11-14)
This dissertation compared lucerne dry matter production from 10 genotypes in irrigated conditions at Lincoln University. First year yields averaged 10 t DM/ha for the establishment year with no differences found among culitvars.
Studies on the Efficacy of Three Trichoderma atroviride Isolates for Controlling Take-all (Gaeumannomyces graminis var. tritici) in Grasses
(Lincoln University, 2018)
Take-all, caused by the fungal pathogen Gaeumannomyces graminis var. tritici (Ggt), is an internationally important widespread root disease of cereals and grasses. The disease is suspected as the main cause of the increasing ...
Effect of row width and plant population density on yield and quality of maize (Zea mays) silage
(Lincoln University, 2017-03-27)
The study reported in this thesis was conducted during 2015/2016 at Lincoln University, New Zealand, to investigate the effect of row width and plant population density on yield and nutritive quality of maize silage (Pioneer ...
An evaluation of cocksfoot/lupin pasture as an alternative forage for summer-dry environments
(Lincoln University, 2016-11-14)
The aim of this study was to evaluate the animal and herbage productivity of a perennial lupin/cocksfoot pasture mix when compared with a lucerne pure sward positive control in a summer dry environment, at Lincoln University, ...
Carbonaceous soil amendments to reduce plant uptake of Cd in NZ’s agricultural systems
(Lincoln University, 2017-03-06)
Cadmium (Cd) is a non‐essential trace element that accumulates in agricultural soils through the application of Cd-rich phosphate fertiliser and industrial activity. Plants can accumulate Cd to concentrations that sometimes ...
Agronomic factors affect powdery scab of potato and amounts of Spongospora subterranea DNA in soil
(Springer on behalf of the Australasian Plant Pathology Society, 2014-11)
Severe powdery scab (caused by Spongospora subterranea) occurred in potato tubers harvested from a field trial, which measured effects of agronomic treatments (nitrogen fertiliser rates, irrigation intensities, previous ...
