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 ...
Response surfaces of growth and yield of wheat
(Lincoln College, University of Canterbury, 1979)
In the 1976-77 and 1977-78 seasons four field experiments using a three factor central composite second order design in incomplete blocks were conducted to quantify the responses of autumn-sown wheats established at five ...
Tiller population dynamics in wheat
(Lincoln College, University of Canterbury, 1978)
In field-sown wheat grown in Canterbury, variation in the density of ears accounts for most of the differences between grain yields (Dougherty 1973; Scott 1978; Scott et al. 1977). Ear number is a component of yield which ...
Some environmental effects on the water status of wheat
(Lincoln College, University of Canterbury, 1977)
The influence of soil moisture status and various meteorological parameters on the water relations of wheat were studies both in the field and under controlled environment conditions. Water potentials of the leaf and ear ...
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 ...
