The effect of the lime-molybdenum interaction on some properties of pasture soils
… may mean the difference between low and high pasture production. It appears that molybdenum will continue to be used in this country for numerous trials have indicated that as far as pasture production is concerned, a few ounces of molybdenum give results as good as several tons of lime in …

A study of some soil fertility problems in Canterbury
… the capability of some of them to give maximum pasture productions in recent years. Since productivity largely depends on soil fertility, it is of utmost importance that the latter be improved and its problems investigated and solved, if the former is expected to improve likewise. Undeniably the …

Changes in δ¹⁵N in pastoral soils under varying management intensity
… by measur ing δ¹⁵N in soils from four forest-to-pasture chronosequences, and in archived soils from six long-term (4–57 year) grazed field trials with different fertiliser or irrigation regimes. Three of the forest-to-pasture chronosequences were on pumice soils where pine forests had been …

Growth of pasture species in the shade in relation to alder silvo-pastoral systems : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy (Ph.D.) in Pastoral Science, Institute of Natural Resources at Massey University, New Zealand
… between tree species and understorey pastures is required for the development of deciduous tree based silvo-pastoral systems. In particular, the shade tolerance of pasture species likely to be used under trees in New Zealand needs to be determined. This thesis examines the effects of …

Nitrogênio Ureico no Leite (NUL) e no Plasma (NUP) de vacas leiteiras suplementadas com níveis crescentes de proteína bruta no concentrado
The pasture production system is an alternative low cost alternative in the production of dairy cattle and it is possible to use concentrated supplementation to better meet the nutritional requirements of the animals. Thus, the objective of this study was to evaluate the protein efficiency use in …

Distribution of nematodes in pasture soil across seasons and in combination with plant species and fertiliser application
… and the selection of highly productive pasture plant species to increase pasture production. When choosing a ryegrass cultivar infected with selected endophyte fungus, ploidy choices are vital for determining pasture production. Modern perennial ryegrass cultivars and White clover plant …

Next generation dairy systems for Canterbury: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
… Efficient (LSE) (3.5 cow/ha). HSE recorded high production per hectare for both milksolids and pasture production (2369 kgMS/ha & 19417 kgDM/ha) pasture quality was also high (11.8 MJME/kgDM) while production per cow was lower than LSE but still competitive with current systems (474 kgMS/cow). …

A systems approach to the economic evaluation of nitrogen fertiliser use in sheep farming enterprises
… farming enterprises which depend on seasonal production of grass-legume pastures as the main source of feed. Nitrogen fertiliser has not been widely used in grass-legume based pastoral systems. These farming systems have instead relied on nitrogen fixation by legume-rhizobia symbiosis as the …

Shade tolerance of tropical forage legumes for use in agroforestry systems
… However, the significant acceptance of tree-pasture (silvopastoral) systems has been impeded by the belief that productive pasture cannot be maintained under tree canopies. The aims of this project were to identify forage legume species suitable for use in silvopastoral systems in order to …

From forest to pasture without weeds: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
Dry matter production, botanical composition and seedling size of a ryegrass/ subterranean clover pasture sown on 1 April out of Pinus radiata were measured over three harvest dates (28 July, 17 August, 7 September) in Darfield (43° B'S, 172° 8'E). Pasture was grown at 4 lime rates (0, 2.5, 5, 10 T …

The effect of drought and rising temperatures on total factor productivity in pasture-based dairy farming in the Eastern Cape
… The study is of the total factor productivity of pasture-based dairy production systems in the Eastern Cape. An unbalanced panel dataset of 206 observations collected from 62 farms over nine years was used to fit a stochastic frontier production function with technical inefficiency effects. …

The effects of production techniques on the yield and quality of some leafy vegetables
… space and technology to expand and enhance production of fruit and vegetables. Growers always strive to obtain maximum yields of high quality produce from their fields. Many factors such as climate, suitable cultivars, cultivation practices, soil, availability of water and nutrients can …

A comparison of two phosphorus soil tests as inputs to a pasture growth model : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Soil Science at Massey University
… of a simple model designed to predict relative pasture yield as a function of soil and fertilizer phosphorus. The relationship between yield and water-extractable soil P differed markedly between two soils of different P retention properties in glasshouse studies using both intact cores and …

An analysis of lambing ewes three times in two years in Southland
… used to determine stock numbers carried and lamb production under each of the conception and feeding regimes studied. Feasibility of each system is dependant on average pasture cover remaining above the minimum required pasture cover (to achieve desire intakes) at all times. Results from feed …

Environmental drivers of bulb production in brassicas
… are used as supplementary feed in intensive pastures systems. However, there is a lack of quantitative data to define their growth and development. This has limited the creation and use of prediction models and decision support systems. Thus a series of experiments were used to clarify the …

Oilseed rape: A study of production and end uses : A dissertation submitted in partial fulfilment of the Diploma in Farm Management at Lincoln College
The purpose of this study is to outline to the farmer the principles and practices of growing a successful oilseed rape crop. It also looks in to the commercial side of marketing the oilseed produce.

Irrigation scheduling: a soft adaptor to weather uncertainties and irrigation efficiency improvement initiatives
… to maintain an appropriate equilibrium between pasture production and environment protection, achievable through the proper management/utilization of agricultural water, for which application and expansion of carefully identified and evaluated irrigation scheduling can play a key role. The focus …

Effect of processing on the distribution of cadmium in wheaten products
An understanding of the cadmium levels in the Australian wheat crop and areas of elevated levels that may be of concern to health has great potential for both the export market and the domestic consumer in Australia. This understanding is most effective if the sources of the cadmium in the wheat, …
