Effects of 15N-labelled crop residues and management practices on subsequent winter wheat yields, nitrogen benefits and recovery under field conditions
(Cambridge University Press, 2001-02)
Nitrogen-15 enriched ammonium sulphate was applied to micro-plots in a field in which two leguminous (white clover and peas) and two non-leguminous (ryegrass and winter wheat) crops were grown to produce ¹⁵N-labelled crop ...
Studies on the luteoviruses potato leaf roll virus, beet western yellows virus and tomato yellow top virus: a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in the University of Canterbury [Lincoln College]
(Lincoln College, University of Canterbury, 1988)
Overseas, beet western yellows virus (BWYV) has been implicated in the leaf roll disease of potatoes, considered to be caused by potato leaf roll virus (PLRV). A project was initiated to determine if BWYV was infecting ...
Components of grain yield and total nonstructural carbohydrates in wheat : a thesis submitted for the degree of Doctor of Philosophy in the University of Canterbury [Lincoln College]
(Lincoln College, University of Canterbury, 1985)
Responses of autumn-sown wheat crops to various agronomic inputs were investigated in three field experiments over two seasons, and the causes of yield variation were analysed by simultaneous carbohydrate measurements in ...
Noninvasive recovery and detection of possum Trichosurus vulpecula DNA from bitten bait interference devices (WaxTags)
The brushtail possum is a major agricultural and ecological pest in New Zealand. A novel noninvasive DNA sampling tool for detecting its presence (WaxTags, or WT) was tested. DNA was recovered from saliva left on WT, and ...
