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, ...
Sulphur cycling in soil-plant-animal systems under grazed, irrigated pastures in Canterbury, New Zealand and its implication on pasture sulphur requirements
(Lincoln University, 1990)
A laboratory study was conducted to investigate whether the zinc acetate-sodium acetate (Zn-Na acetate) solution that has often been used in the Iohnson-Nishita method (1952) to trap hydrogen sulphide (H₂S) and allow more ...
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 ...
Availability of phosphate fertilizers in unlimed and limed acid soils as affected by wetting and air-drying
(Lincoln University, 1991)
The interactions between air-drying and rewetting, and liming or timing of phosphate (P) fertilizer application on plant availability of monocalcium phosphate (MCP) or reactive phosphate rock (PR) fertilizers were studied ...
Genetically modified broccoli (Brassica oleracea L. var. italica) containing an antisense acc oxidase gene
(Lincoln University, 1999)
In broccoli, post-harvest senescence is rapid, with loss of chlorophyll resulting in the yellowing of sepals from immature florets. Associated with this deterioration is an increase in ethylene production. In order to delay ...
A study of insect pests of brussels sprouts in Canterbury; their phenology and the resultant crop losses
(Lincoln College, University of Canterbury, 1982)
The relationships between insect pests and damage in Brussels sprouts were studied for three seasons in Canterbury. Each season the major pest species, white butterfly (Artogeia rapae L.), diamondback moth (Plutella ...
Plant parasitic nematodes: the effect of lolines.
(Lincoln University, 2008)
Grass endophytes live their entire life cycle within the aerial portion of the grass host,
with which they form a defensive mutualism. The endophyte which resides
intercellularly within the grass, synthesizes an array ...
Ecology and management of Himalayan thar and sympatric chamois in the Southern Alps, New Zealand
(Lincoln University, 1997)
This thesis investigated aspects of the ecology and management of Himalayan thar (Hemitragus jemlahicus) and sympatric chamois (Rupicapra rupicapra) in the eastern Southern Alps of New Zealand.
The hypothesis that ...
Burrow occupancy and related behaviour of broad-billed prions Pachyptila vittata on South East (Rangatira) Island, Chatham Islands, New Zealand
(Lincoln University. Ecology and Entomology Group, 1998-07)
Burrow competition is occurring between broad-billed prions (Pachyptila vittata) and other small burrowing seabirds on South East (Rangatira) Island, Chatham Islands, New Zealand. This competition has a negative impact on ...
Carotenoid pigmentation of chinook salmon (Oncorhynchus tshawytscha)
(Lincoln University, 1992)
Carotenoid pigmentation of chinook salmon under commercial conditions was investigated in a series of experiments carried out in fresh water and salt water. The carotenoid composition of salmonids and factors regulating ...
