Strategies to improve sheep liveweight gains and dry matter production of dryland tall fescue/clover pastures in Canterbury
(Lincoln University, 2014)
This study examined ways to improve sheep liveweight gains and dry matter production on dryland Canterbury farms using tall fescue/clover pastures. There were four pasture mixes sown in 2008 at Lincoln University. Each ...
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 ...
Intraspecific differences in the response of perennial ryegrass (Lolium perenne L.) to drought
(Lincoln University, 2016-11-14)
Perennial ryegrass (Lolium perenne L.) has traditionally been the grass species of choice for most New Zealand regions and is currently an important component of our highest-producing pastures. However perennial ryegrass ...
Dry matter production and water use of dryland cocksfoot/lupin and lucerne pastures in the third year after establishment
(Lincoln University, 2017-11-14)
Cocksfoot (Dactylis glomerata) is a preferred grass option for dryland pastures on high country farms in the South Island of New Zealand. However, increasing the productivity of cocksfoot based pastures with legumes is ...
The influence of ryegrass sowing rates and nitrogen fertiliser on white clover establishment : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 2004)
Perennial ryegrass (Lolium perenne L.) pastures were sown on 19 February at four sowing rates (0, 5, 10, 20 kg/ha) with four rates of nitrogen fertiliser (0, 20, 40, 80 kgN/ha). White clover (Trifolium repens L.) was sown ...
Livestock and pasture production from dryland lucerne and two lucerne/grass mixtures over four years in Canterbury
(Lincoln University, 2017)
The productivity of a lucerne monoculture, lucerne/brome and lucerne/cocksfoot binary mixtures grown on shallow soils at Ashley Dene, Canterbury, were compared under grazing over four years. Pastures were grazed with ...
Dry matter yield and tiller development of perennial ryegrass/white clover swards in response to autumn applied nitrogen : A dissertation submitted for partial fulfilment of the requirement for the degree of Bachelor of Agricultural Science with Honours
(Lincoln University, 2010)
The timing of N application in autumn determines the pasture response. A field experiment was conducted to investigate effects of N fertiliser rate (O (N1) and 100 (N2) kg N/ha) and defoliation height (40 (Hl) and 80 (H2) ...
Sodium deficiency in sheep pastures : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agriculture Science with Honours at Lincoln University
(Lincoln University, 2002)
Sodium (Na) is not essential for plant growth however it is required by grazing ruminants. Natrophobic species are usually deficient for animal nutrition (<0.10% Na) while natrophiles have adequate Na contents except for ...
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. ...
The value of reduced-rate insecticide applications in achieving differential mortality of the lettuce aphid Nasonovia ribisnigri (Mosley) (Hemiptera: Aphididae) and one of its predators, the Tasmanian lacewing Micromus tasmaniae (Walker) (Neuroptera: Hemerobiidae : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Science with Honours
(Lincoln University, 2004)
The application of reduced-rate concentrations of insecticides has potential as a component of integrated pest management (IPM). This is because there is theoretical and practical evidence that the survival of predatory ...
