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 ...
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 ...
