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). ...
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 ...
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 ...
Inheritance and selection in two New Zealand wheat crosses
(Lincoln College, University of Canterbury, 1982)
The objective of this study was to evaluate the inheritance of yield per plant and yield components, their responses to single plant selection in F₂, and line selection in F₃ of the two crosses, Hilgendorf x Oroua and ...
Components of grain yield in wheat : a thesis submitted for the degree of Doctor of Philosophy in the University of Canterbury [Lincoln College], New Zealand
(Lincoln College, University of Canterbury, 1977)
Between 1972 and 1976 a series of field experiments were conducted to investigate the factors limiting grain yield in
wheat (Triticum aestivum L). Spike population restricted yield
when it was below about 500 spikes/m² ...
