The Proceedings of the Lincoln College Farmers' Conference 1983
(Lincoln College (Lincoln, N.Z.)., 1983)
The Lincoln College Farmers’ Conference was an annual event held over a period of thirty six years from 1951 to 1986. It was a forum for farmers with participation in the early years by district nomination. The strength ...
Growth of the grass plant in relation to seed production
(New Zealand Grassland Association, 1980)
The specialized management techniques required for successful seed production in grasses must be based on a sound understanding of the physiology of the plant. Seed yields depend strongly on the number of ears per unit ...
Early generation selection in 2 wheat crosses 1. F₂ single plant selection
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1985)
In an analysis of 2 wheat crosses, it was shown that yield components had higher heritabilities than grain yield per plant. Single F₂ plant selection for grain number per spikelet and per ear increased the yield per plant ...
Early generation selection in 2 wheat crosses 2. F₃ line selection
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1985)
Direct selection for grain number per spikelet, grain number per ear, or weight per grain was more effective than selection for yield per se as indicated by direct responses and realised heritabilities. Yield per plant did ...
Effects of sowing rate, irrigation, and nitrogen on the components of yield of spring-sown semidwarf and standard New Zealand wheats
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1975)
'Karamu', a Mexican semidwarf wheat, outyielded 'Aotea' and 'Arawa' by an average of 20% when spring sown because of better grain set per spikelet and by the formation of more spikelets per ear. Irrigation raised grain ...
Pattern and control of distribution of ¹⁴C-assimilates in reproductive plants of Lolium multiflorum Lam. var. Westerwoldicum
(Oxford University Press, 1975-07-01)
The distribution of ¹⁴C-assimilates was examined in reproductive plants of Lolium multiflorum Lam. var. Westerwoldicum (cv. Tama) from which all emerged tillers had been removed, leaving the main tiller with two expanding ...
Levels of water-soluble carbohydrate in the pre-anthesis ear of wheat, and grain set per spikelet
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1975)
Low levels of water-soluble carbohydrates in wheat ears before emergence were associated with poor grain set per spikelet when seeding rates were approximately twice conventional ones. Grain set and grain filling in 'Arawa' ...
Crown development of two diverse genotypes of lucerne
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1977)
Crown development of 'Moapa' (Medicago sativa L.) and 'College Glutinosa' (M. media Per.) lucernes was examined under simulated sward conditions. The crown included all shoots originating from nodes less than 6 mm apart ...
Development and yield components of high-yielding wheat crops
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1977)
In a field experiment, 'Arawa' wheat outyielded 'Aotea' by 10% through the production of a higher grain yield per ear. Irrigation had no effect on grain yield because of plant uptake of subsoil moisture. Nitrogen increased ...
An analysis of a wheat yield depression caused by high sowing rate with reference to the pattern of grain set within the ear
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1975)
Grain set in spikelets of ears was reduced in spring-sown wheat established at high sowing rate (500 viable seeds/m²) compared with wheat planted at normal rates (250 seeds/m²), the reduction being greatest in spikelets ...
