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 ...
Variability of harvest index in four grain legume species
(Lincoln University, 2001)
Grain legumes have the potential to be high yielding crops in Canterbury. However, like most grain legumes the problem of harvest index (HI) variability in Cicer arietinum, Lens culinaris, Lupinus angustifolius and Pisum ...
Harvest index variability within and between field pea (Pisum sativum L.) crops
(Lincoln University, 1993)
The association between individual plant performance and seed yield variability within
and between field pea crops was investigated. In 1988/89 six F8 genotypes with
morphologically distinct characteristics were selected ...
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 ...
Environmental control of tillering and yield of wheat
(Lincoln College, University of Canterbury, 1985)
Four experiments were conducted in controlled and field environments from 1982 to 1984 to establish relationships between dry matter growth rate and tillering, yield components and grain yield of wheat.
In the first ...
The effects of plant population, growth regulators and irrigation on development and yield of spring sown field beans (Vicia faba L.)
(Lincoln College, University of Canterbury, 1985)
Two field experiment were conducted during the years 1982/83 and 1983/84 to investigate the effect of two foliar applied plant growth regulators (PGRs) TIBA and paclobutrazol (PP333), on field beans (Vicia faba L.) cv. ...
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 ...
The influence of cultivar and environment on the relationship between flour protein content and grain yield in wheat
(Lincoln College, University of Canterbury, 1985)
Two field experiments were conducted on different soil types and locations in Canterbury during the 1981/82 and 1982/83 growing seasons. Genetic variability in grain yield and flour protein content (protein content) of ...
Disease management of Ascochyta fabae Speg., a seed borne pathogen of Vicia faba L.
(Lincoln College, University of Canterbury, 1984)
Ascochyta fabae was present in all the field and broad bean crops surveyed in the Canterbury and Marlborough areas during the 1978/79 and 1979/80 seasons. In broad bean crops, the disease incidence on the flowering nodes ...
Density and irrigation studies in Lupinus albus and L. angustifolius
(Lincoln College, University of Canterbury, 1977)
Interest in sweet lupins as a possible source of high quality protein prompted the studies reported in this thesis. At the time of the inception of these studies several scientific groups in Australia and New Zealand were ...
