Harvest index variability within and between field pea (Pisum sativum L.) crops
(Lincoln University, 1993)
The association between individual plant performance and seed yield variability within
and between field pea crops was investigated. In 1988/89 six F8 genotypes with
morphologically distinct characteristics were selected ...
Yield and composition of lucerne strands in Central Otago after different winter grazing and weed control treatments
(New Zealand Grassland Association, 2014-12-01)
The effect of grazing date and time of spraying with a glyphosate/atrazine herbicide combination on a three year-old lucerne stand was studied on-farm in Central Otago. Total annual dry matter (DM) yield was highest in the ...
Clover growth in response to naturalised P-solubilising bacteria in New Zealand
(2014-09-30)
For New Zealand pastures the main fertiliser costs are associated with the delivery of nitrogen (N) and phosphate (P). With recognition that increased consumption of N and P fertilisers and the augmentation in soil Olsen-P ...
Causes of leaf reddening in subterranean clover cultivars
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-04-30)
Subterranean clover (Trifolium subterraneum L.) is an important legume in dryland hill pastures in New Zealand. In this environment plants adapt to low temperatures (<10°C) through a series of physiological mechanisms, ...
Medium-term soil pH and exchangeable aluminium response to liming at three high country locations
(NZGA, 2014-12-01)
Acid soil conditions and associated aluminium (Al) toxicity pose a serious impediment to legume establishment, persistence and productivity in high country. However, data that report soil exchangeable Al concentrations in ...
The mechanisms driving potato crop yield and grade distribution
Under ideal growing conditions (e. g. optimal moisture, temperature, mineral nutrition and disease control) potato dry matter (DM) yield increases with the amount of intercepted photosynthetic active radiation (PARi). ...
Soil pH, exchangeable aluminium and legume yield responses to deep-placed lime at Omarama Station
(New Zealand Grassland Association, 2018-11-17)
The passive moment of lime down the soil profile in dryland is slow so a machine was developed to directly inject lime into soil, and was tested it at Omarama Station. Pelleted lime was injected at simultaneous depths of ...
Soil acidity and aluminium in South Island high and hill-country: New data and future needs
(New Zealand Grassland Association, 2018-11-19)
Soil extractable aluminium (A1) concentrations can have a strong impact on the establishment, growth and persistence of pasture legumes. This has become clear in New Zealand high and hill-country, where legumes are scarce ...
A field survey of soil pH and extractable aluminium in the Ashburton Lakes Catchment, New Zealand
(New Zealand Grassland Association, 2018-11-13)
Soil extractable aluminium (Al) concentrations have a strong impact on the establishment, growth and persistence of pasture legumes. A survey of 21 soil profiles in the Ashburton Lakes catchment was conducted to ...
Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
