The growth of grasses and legumes on a sequence of acid soils as affected by liming and phosphate fertiliser
(Lincoln College, University of Canterbury, 1974)
The causes of differential growth of lucerne, lotus, ryegrass and brown top on a range of three acid soils were investigated by means of pot trials carried out in the glasshouse.
Of the four species, lucerne was affected ...
An analysis of a nitrogen-induced depression of yield in irrigated 'Kopara' wheat
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1974)
Heavy applications of nitrogen fertiliser (200 kg/ha) applied in early spring to wheat (Triticum aestivum L. cv. 'Kopara') on a Wakanui silt loam, in which irrigation was used to maintain soil-water levels above -0.5 bar, ...
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 ...
Response of irrigated lucerne to defoliation and nitrogen fertiliser
(Taylor & Francis on behalf of the Royal Society of New Zealand, 1974)
A 3-year-old stand of lucerne (Medicago media Per.) cv. 'Wairau' was spray irrigated and subjected to three defoliation frequencies from spring to autumn, after which all plots received a common management. Nitrogen ...
