Effect of temperature on development of Listronotus bonariensis (Kuschel) (Coleoptera: Curculionidae) on Lolium perenne (L.) (Gramineae: Festucoidae)
(Lincoln University, 1999)
Argentine stem weevil (ASW) Listronotus bonariensis (Kuschel) is an introduced species that attacks improved graminaceous pasture and crop throughout much of New Zealand. It is recognised as the most important arthropod ...
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 ...
Dynamics of ammonia volatilization and nitrous oxide production from urine patches in grazed pastures
(Lincoln College, University of Canterbury, 1984)
A continuously aspirated enclosure method was used to measure ammonia (NH₃) volatilization from simulated sheep urine patches in a perennial ryegrass (Lolium perenne) / white clover (Trifolium repens) pasture in the field ...
A Study of the fate and transport of estrogenic hormones in dairy effluent applied to pasture soils
(Lincoln University, 2009)
The disposal of waste from agricultural activities has been recognised as a source of environmental contamination by endocrine disrupting chemicals (EDCs). The New Zealand dairy industry produces a large volume of dairy ...
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) ...
Genotypic evaluation of Trifolium ambiguum
(Lincoln College, University of Canterbury, 1979)
A number of morphological, floral, rhizome, root and herbage characteristics were studied in order to describe genetic variation and environmental responses in T. ambiguum. From each of six lines, 30 genotypes were clonally ...
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 ...
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, ...
The effects of hormones and temperature on the initiation of inflorescences and tendrils and the morphology of shoots and roots in grapes
(Lincoln College, University of Canterbury, 1985)
The experiments reported investigated the response of buds, shoots and roots of Vitis vinifera L. cv. Riesling to hormones and temperature. They were done on one-year-old one-node potted cuttings growing in a shadehouse ...
