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 ...
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 ...
An evaluation of irrigation-yield repsonse models for use with wheat & barley in Canterbury, New Zealand
(Lincoln College, University of Canterbury, 1986)
This study evaluated the ability of nine models to describe and
predict the response of grain yield to flood irrigation of wheat and
barley crops. The models may be divided into four groups:
1). Input-Output models
2). ...
Quality in the New Zealand wheat and flour markets
(Lincoln College. Agricultural and Economics Research Unit., 1982-12)
Interest in the quality of New Zealand wheat and flour is
ever ongoing. A further catalyst to interest in the topic was the
announcement that New Zealand farmgate wheat prices would be directly linked
with world prices ...
Effects of different crop residues and management practices on soil nitrogen dynamics, yield and recovery of nitrogen by wheat
(Lincoln University, 1998)
In a large field experiment on an irrigated Templeton silt loam (Udic Ustochrept) soil using a completely randomised block design with six replicates (each main plot = 30 x 20m), main plot treatments of wheat and ryegrass ...
The development of a sequential sampling plan for management of stripe rust (Puccina striiformis West.) in winter wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1985)
Stripe rust caused by Puccinia striiformis West., was studied in three seasons between 1981 and 1984, on the susceptible wheat cv. Rongotea. A sample unit of the top three leaves on a W-shaped sample pattern provided the ...
Economic factors affecting wheat areas within New Zealand
(Lincoln College. Agricultural Economics Research Unit, 1979-12)
A stated objective of the current Government's wheat policy is that New Zealand should be self sufficient in the production of wheat. A means by which this could be achieved is through changes in the announced price for ...
Natural self-fertilization of wheat on a large scale
(New Zealand Institute, 1923)
Tests the hypothesis that frost of a certain intensity can lead to the cross-fertilization of wheat on a large scale, and that this can be one cause of the occurrence of new varieties.
An analysis of alternative wheat pricing schemes
(Lincoln College. Agricultural Economics Research Unit., 1980-09)
The aim of this study was to measure, from an economic efficiency viewpoint, the impact of making the domestic wheat pricing scheme more responsive to changes in the world wheat price. This was done by distilling information ...
Yield structure and pre-anthesis carbohydrate status of wheat
(Lincoln College, University of Canterbury, 1980)
In the 1977-78 and 1978-79 seasons, three field experiments were conducted on a deep moisture retentive soil to investigate the
responses of wheat yield to various seeding rates, rates and times of
N application, and ...
