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 ...
Sustainable restoration of mine sites
(Lincoln University, 2009)
A sustainable approach to restoration of the post-mining landscape involves creating conditions where a viable growth medium can be established with the minimal amount of fertiliser inputs over a period of time. Ideally, ...
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 ...
Effect of physiological and behavioural characteristics of parasitoids on host specificity testing outcomes and the biological control of Paropsis charybdis
(Lincoln University, 2010)
An established host-parasitoid-hyperparasitoid system was used to investigate how the physiological and behavioural characteristics of parasitoids influence the outcomes of laboratory-based host specificity tests. The ...
Mineral nitrogen regimes in soils of natural and modified snow tussock grasslands of Canterbury and Otago, New Zealand
(Lincoln College, University of Canterbury, 1983)
Mineral nitrogen (N) levels in natural grasslands of the world fluctuate in response to a range of environmental influences but are generally low with ammonium (NH₄-N) levels usually below 10 µg g⁻¹ soil and nitrate (NO₃-N) ...
Variability of harvest index in four grain legume species
(Lincoln University, 2001)
Grain legumes have the potential to be high yielding crops in Canterbury. However, like most grain legumes the problem of harvest index (HI) variability in Cicer arietinum, Lens culinaris, Lupinus angustifolius and Pisum ...
Nitrogen fixation in peas (Pisum sativum)
(Lincoln College, University of Canterbury, 1983)
Field experiments were conducted at Lincoln College, Canterbury, from 1979-81 to assess the effect of peas (pisum sativum) on subsequent crops and evaluate factors influencing their N-fixing activity.
In two trials, ...
The effect of subsoiling on plant nutrition and pasture production
(Lincoln University, 1993)
An eighteen month field trial was conducted to determine the effect of soil loosening on plant nutrition and pasture production.
The field trial was conducted on an established (8 year old) mixed sward pasture. The soil ...
