Nitrogen fixation in peas (Pisum sativum)
(Lincoln College, University of Canterbury, 1983)
Field experiments were conducted at Lincoln College, Canterbury, from 1979-81 to assess the effect of peas (pisum sativum) on subsequent crops and evaluate factors influencing their N-fixing activity.
In two trials, ...
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 ...
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. ...
The effects of subsoiling on soil physical properties and crop production
(Lincoln College, University of Canterbury, 1989)
In the Canterbury and North Otago regions of New Zealand, many intensively cropped yellow-grey earths contain subsoils which have become compacted by traffic and/or natural processes and which therefore restrict root growth ...
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 response of field bean (Vicia faba L.) to irrigation and sowing date
(Lincoln College, University of Canterbury, 1984)
The response of autumn and spring sown crops of Vicia faba cv. 'Maris Bead' to irrigation applied during the vegetative, flowering and pod-filling phases was investigated during the 1981/82 and 1982/83 seasons on a Templeton ...
The effects of root modification on growth, water use, and yield of Vica faba L.
(Lincoln College, University of Canterbury, 1988)
Dense subsoil layers in some Canterbury soils often provide mechanical resistance sufficient to prevent root growth into subsoil layers. This can increase crop susceptibility to drought stress, resulting in a reduction in ...
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 ...
Environmental influences on the growth, development and yield of pinto beans (Phaseolus vulgaris L.)
(Lincoln University, 1997)
The effect of the environment (sowing dates and seasons), irrigation and inoculation on the growth, development and yield of pinto beans (Phaseolus vulgaris L.) cv. Othello was investigated in two seasons on a Wakanui silt ...
The effect of irrigation on radiation absorption, water use efficiency and yield of conventional and semi-leafless peas
(Lincoln College, University of Canterbury, 1984)
The growth, water use and yield of conventional and semi-leafless peas were studied for two spring sowings
under dryland and irrigated conditions on a Templeton silt loam soil at Lincoln during the 1981/82 season. Irrigation ...
