The effects of foliar diseases and irrigation on root development, yield and yield components of wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1985)
Studies were conducted on three field trials of wheat cv. Kopara to investigate the lack of compensation by later determined components of yield because of early disease constraints. The investigation was based on the ...
Simulation-based design of water harvesting schemes for irrigation
(Lincoln College, University of Canterbury, 1981)
For large areas of New Zealand that suffer from agricultural drought, the only practicable way of providing irrigation is through the use of water harvesting schemes that divert winter flood water in nearby streams into ...
An information system for planning agricultural development in the Kingdom of Tonga
(Lincoln College, University of Canterbury, 1980)
Past development efforts in the Kingdom of Tonga are reviewed in relation to the goals of reducing poverty, unemployment and inequality. It is shown that progress has been strictly limited and evidence is provided to support ...
The monitoring of complex natural systems - aspects of ecosystem management using wetlands as examples
(Lincoln University, 1998)
The Resource Management Act (1991) created a major shift in the legislative framework for environmental management in New Zealand. The Act devolved power to local and regional government, and focused on the environmental ...
The influence of Hoki fishing vessels on Westland Petrel (Procellaria westlandica) distribution at sea
(Ornithological Society of New Zealand, 1997-09)
The Westland Petrel (Procellaria westlandica) population is thought to have increased significantly in recent decades, perhaps as a result of increased food in the form of waste from fishing vessels. A survey of Westland ...
Risk and uncertainty
(Lincoln College and University of Canterbury. Centre for Resource Management., 1988-07)
This paper presents an overview of the risk literature, concentrating on general
approaches to risk analysis and risk assessment. We believe that this is an essential first step towards the setting of guidelines or the ...
Poisoning mammalian pests can have unintended consequences for future control: two case studies
(New Zealand Ecological Society, 1999)
Vertebrate pest control operations using toxic baits can have unintended consequences for nontarget species. some of which may themselves be pests. Learned avoidance behaviour (termed 'aversion') can be induced by sublethal ...
Humic acid protonation, metal ion binding and metal complex dissociation kinetics
(Lincoln University, 1990)
Two humic acids have been studied in terms of: (i) their ability to bind H⁺, Cd²⁺ and Cu²⁺, and; (ii) the rates of dissociation of their Cu²⁺ complexes.
For both Summit Hill and Waimari Peat humic acids, the protonation ...
Intraspecific variation in Microctonus hyperdoae and M. aethipopides (Hymenoptera: Braconidae); significance for their use of biological control agents
(Lincoln University, 1995)
Microctonus aethiopoides Loan and M. hyperodae Loan (Hymenoptera: Braconidae; Euphorinae) are parasitoids introduced to New Zealand to assist suppression of the lucerne pest Sitona discoideus Gyllenhal and the pasture pest ...
Risk management strategies for the long run use of resources: the impact of climate change on agriculture
(Lincoln University. Centre for Resource Management., 1992-07)
This publication is the result of a research contract completed for MAF Rural Policy Unit in 1991.
The brief was to develop a policy framework to assist in the analysis of the issues raised by climate change and the ...
