Liming effects on legume production and phosphorus availability in acid South Island hill and high country soils : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
There is large potential for widespread development and increased production in South Island hill and high country by increasing legume production. Despite regular past applications of superphosphate fertiliser, current ...
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, ...
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 ...
Pasture regeneration and gorse seedling control in the Port Hills following fire
(Lincoln University, 2017-11-14)
This dissertation examined the regeneration of pasture after a fire and the control of gorse seedlings using Italian ryegrass competition and herbicides. The experiments were run at a property on the Port Hills, Canterbury ...
Reduction of nitrogen losses by manipulating carbon inputs and pasture composition : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
The nitrogen (N) cycle is very important to New Zealand agriculture, with N being a key nutrient needed for plant growth. However, there are major environmental concerns relating to the loss of N from agricultural systems. ...
Irrigation effects on soil organic carbon under a ryegrass-white clover pasture on a Lismore stony silt loam soil : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
Long-term summer irrigation of temperate managed pastures has been reported to either increase or decrease soil organic carbon (SOC) stocks when compared with dryland systems. Understanding the short-term effects of ...
Enhancing seed quality in the female spinach (Spinacia oleracea L.) parent line : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Hybrid spinach (Spinacia oleraceae L.) seeds are produced in New Zealand for export. However, some seed lots fail to meet contracted germination standards. Several factors that may be responsible for seed germination and ...
A tale of two grass species: Temperature affects the symbiosis of a mutualistic Epichloë endophyte in both tall fescue and perennial ryegrass
(Frontiers Media SA, 2020-05-08)
Many cool-season grasses form permanent, mutualistic symbioses with asexual Epichloë endophytes. These fungal symbionts often perform a protective role within the association as many strains produce secondary metabolites ...
Influences of removing linear and nonlinear trends from climatic variables on temporal variations of annual reference crop evapotranspiration in Xinjiang, China
(Elsevier, 2017-08-15)
Reference crop evapotranspiration (ET₀) is a key parameter in field irrigation scheduling, drought assessment and climate change research. ET₀ uses key prescribed (or fixed or reference) land surface parameters for crops. ...
