Wheat yield as affected by sowing rate, irrigation, and time of white clover introduction
(Taylor & Francis, 1973)
On a fertile, moisture-retentive Wakanui silt loam Aotea wheat sown at 100 kg/ha yielded 6650 kg/ha, considerably more than when sown at 50 or 150 kg/ha. Lower yields of wheat planted at the 50 kg/ha rate were caused largely ...
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 ...
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' ...
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 ...
