Evaluating the SIRIUS wheat crop simulation model in Canterbury : a dissertation submitted in partial fulfilment of the degree of Bachelor of Agricultural Science with Honours at Lincoln University, Canterbury, New Zealand
(Lincoln University, 2003)
An on-farm trial was conducted in an irrigated commercial wheat crop on a property near Dorie in the 2001/2002 and 2002/2003 seasons to validate the SIRIUS crop simulation model. Three nitrogen treatments were applied, a ...
A comparison of establishment methods of permanent pasture into an undeveloped depleted tussock grassland : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours, Lincoln University
(Lincoln University, 2007)
This research compared pasture establishment, with or without cultivation, with two drill types, Cross Slot or triple disc and with 0, 2 or 6 t ha ⁻¹ of lime in an herbicided, undeveloped depleted tussock grassland, at ...
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 ...
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 ...
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 ...
Sociability of four clover species with cocksfoot during pasture establishment
(Lincoln University, 2002)
The establishment phase of six pastures was studied over a seven-month period. Four
clover species plus cocksfoot were compared with white clover/ryegrass and lucerne
pastures. All six pastures were sown into a cultivated ...
Sheep urinary lysergyls as a biomarker of exposure to ergovaline: A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Science with Honours at Lincoln University
(Lincoln University, 2003)
Ergovaline is one of the ergot alkaloid toxins produced through association of the endophyte Neotyphodium lolii with perennial ryegrass. Ergovaline affects the health and productivity of sheep grazing ryegrass infected ...

(Lincoln University, 2006)
Continental and Mediterranean tall fescue (Festuca arundinacea Schreber) crosses were transplanted in August 2005 after parent plants were covered with pollen-proof sacs. As part of a larger programme run by AgResearch ...
Understanding how sowing rate and date effect autumn lucerne establishment in Canterbury: A dissertation submitted in partial fulfilment of the requirement for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 2007)
During the summer - autumn of 2006/07 a lucerne establishment experiment was undertaken to determine what sowing rate and date of lucerne is necessary for economic establishment. The affect sowing rate and date had on ...

(2007-05-07)
Plants of two garden pea cultivars were exposed to high temperature (30/25°(; day/night; 12h each) for 4 days at 5 stages during seed development and maturation to determine the effect of high temperature on seed quality ...
