An economic study of wheat-farms in Springs County
(Canterbury Agricultural College, University of New Zealand, 1929)
“Wheat is by far the most valuable plant in the world. It is the main source of food for modern Europe, for much of Asia for America and Australasia.
In view of its importance it is strange that there should be no record ...
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 ...
The effect of genotype and agronomic factors on crop growth and yield in field peas (Pisum sativum L.) as influenced by radiation interception and utilisation
(Southern Cross Publishing, 2014-05)
Three trials were conducted in 2006/07 and 2007/08 growing seasons aiming to find the effect of genotype, crop and weed population densities, herbicide, and sowing date on crop growth and yield in Pisum sativum as influenced ...
Lucerne dry matter and N-fixation, when sown with or without lime and inoculant
(New Zealand Grassland Association, 2015-11)
This paper quantifies the effect of inoculation and lime on lucerne growth and nitrogen fixation over the establishment and following season. The field experiment at Ashley Dene, in Canterbury, had an initial soil pH of ...
The performance of an efficient dairy system using a combination of nitrogen leaching mitigation strategies in a variable climate
(Elsevier, 2017-12-01)
An efficient dairy system, that implemented a combination of nitrogen (N) leaching mitigation strategies including lower N fertilizer input, standing cows off pasture for part of the day in autumn and winter (stand-off), ...
Wheat nitrogen fertilisation effects on the performance of the cereal aphid Metopolophium dirhodum
(MDPI AG, 2012-02-09)
The effects of five rates of nitrogen fertiliser applications on the performance of the cereal aphid Metopolophium dirhodum on winter wheat, within the range of rates recommended for UK crops, were investigated over two ...
Maximising the subterranean clover content on a summer-dry Wairarapa hill-country farm through grazing management
(New Zealand Grassland Association, 2019-11-04)
Tokaroa Farm is a 608-ha sheep and beef farm, in the Wairarapa. Paddock slopes range from flat to steep (>25°) with a predominance of gentler north facing slopes and steeper south facing slopes. Annual rainfall is 810 mm ...
Potential profit gains from improving pasture productivity on New Zealand South Island high-country farms
(New Zealand Grassland Association, 2020-09-09)
Soil acidity combined with low levels of key nutrients on New Zealand hill-country farms are limiting factors for legume establishment/growth. However, legumes are a critical component of these farms as they provide nitrogen ...
The development of a lucerne growth model : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 1992)
Lucerne (Medicago sativa) is a pasture plant which has been grown for over 2000 years, but despite this fact surprisingly little is known about it's regrowth. In the seventies the popularity of luceme was extremely high ...
Grazing and soil fertility effect on naturalized annual clover species in New Zealand high country
(Elsevier on behalf of the Society for Range Management, 2016-11)
With a view to increasing rangeland pasture legume abundance, the herbage biomass and seedling recruitment of four New Zealand naturalized annual clover species (haresfoot clover Trifolium arvense L., suckling clover T. ...
