Climatic and aspect influences on pasture production in New Zealand
(Lincoln College, University of Canterbury, 1979)
In view of the scarcity of published information on pasture production and climate relationships in New Zealand and especially such relationships in hill country these factors were studied at 23 lowland sites throughout ...
Simulated grazing of lucerne: a thesis submitted in partial fulfilment of the requirements for the degree of Master of Agricultural Science in the University of Canterbury [Lincoln College]
(Lincoln College, University of Canterbury, 1972)
Over recent years, there has been a considerable increase in the area of lucerne grown in New Zealand, particularly that used for grazing. The total for conservation and grazing increased from 19,000 ha in 1947 to about ...
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 ...
A comparison of the pattern of grain set in 'Aotea' and 'Karamu' wheat
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1977)
The pattern of grain set and grain size distribution within mainstem ears of a standard New Zealand cultivar 'Aotea' was compared with that in a Norin 10 derivative 'Karamu' when both were spring sown. Karamu produced more ...
Effects of irrigation and fertiliser on the yields of 'Arawa', 'Aotea', and 'Karamu' wheats
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1974)
Grain yields of 'Aotea', 'Arawa', and 'Karamu' wheats were depressed by irrigation during early stages of reproductive development which reduced the number of grains per spikelet and slowed the rate of reproductive ...
