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 ...
The effects of cutting time and post-cutting rainfall on perennial ryegrass seed endophyte survival and seed quality: A dissertation submitted in partial fulfilment of the requirement for the Degree of Bachelor of Science with Honours
(Lincoln University, 2010)
Novel endophyte technologies are now a widely accepted part of modern pastoral agriculture within New Zealand, owing to their production of alkaloids which have been shown to significantly reduce the effects of pasture ...
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 ...
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 ...
Growth and feed quality of five perennial ryegrass (Lolium perenne L.) cultivars under three water treatments
(Lincoln University, 2017-08-02)
Growth and feed quality of five perennial ryegrass cultivars were compared under three water treatments: non-stress (field capacity, FC), mid-stress (50% FC) and high-stress (30% FC). There were three New Zealand cultivars ...
Influence of soil pH, phosphorus and sulphur on the frequency of rhizobia genotypes found in four pasture legume species grown in an acid high country soil
(Lincoln University, 2014)
South Island hill and high country soils typically have deficiencies of nitrogen, phosphorus, sulphur and molybdenum. The soils often have low pH and as such, high levels of exchangeable aluminium and manganese, causing ...
The effect of Neotyphodium grass endophyte on alkaloid profiles, dry matter production and botanical composition of perennial ryegrass pastures
(Lincoln University, 2014)
This study involved three key experiments to examined the effect of Nil endophtye and novel endophyte strains (AR1, AR37, Wild-Type (WT) and NEA2) of perennial ryegrass on dry-matter (DM) production, botanical compositon, ...
Nitrogen fixation and site nitrogen balances of fertilised dryland lucerne (Medicago Sativa L.) at Lincoln University, Canterbury, New Zealand
(Lincoln University, 2014)
Lucerne (Medicago sativa L.) is a high value perennial forage legume. It is deep-tap rooted, has high water use efficiency and is tolerant of drier environments. It produces high quantity and quality dry matter (DM). Yet, ...
An investigation of the incorporation of a standoff facility with the grazing of fodder beet in a Canterbury dairy wintering system
(Lincoln University, 2014)
Dairy farmers are under scrutiny for the negative effect their farming operations have on the environment, particularly in regard to nitrate leaching. The National Policy Statement for Freshwater has directed regional ...
The effect of pre-mowing pasture on milk, pasture, and nitrogen partitioning of dairy cows in the autumn
(Lincoln University, 2014)
The effect of pre mowing on pastures of high or low mass was investigated to determine whether herbage quality, intake, milk yield and nitrogen use efficiency (NUE) of dairy cows could be increased. The experiment was ...
