Timing Of Nitrogen Fertilizer Application For Cereals, M G. Mason Aug 1991

Timing Of Nitrogen Fertilizer Application For Cereals, M G. Mason

Division of Plant Research : Technical Report Series

Results are presented for 206 trials carried out between 1959 and 1990, investigating the effect of time of application of nitrogen fertilizers on cereal grain yields. This set of data is the basis of recommendations made for timing of nitrogen fertilizer application for cereals in Western Australia. Attention is drawn to the variability of results obtained in different seasons and situations and the time of leaching rains.

Management Systems For Sheep., Peter Doyle, L. Cransberg, P. Evans

Experimental Summaries - Plant Research

Trial 89KA6

Performance Of Annual Legumes And Their Mixes Under Different Crop:Pasture Rotation., P. Evans Jan 1991

Performance Of Annual Legumes And Their Mixes Under Different Crop:Pasture Rotation., P. Evans

Experimental Summaries - Plant Research

Trial 86KA64, 86KA65 and 86KA66

Performance of annual legumes and their mixtures under different crop:pasture rotations.

Seed reserves, especially in the 1:1 rotation treatment, are on average below 100 kg/ha and in many cases below 50 kg/ha for all three soil types. Because of this the 1991 season will be used to fertilize, control weeds, and apply a grazing management system to favour legume production and seed set. No crop will be sown in 1991.

Sub clover flowering, sequential sowings.

Location: Katanning

To provide seven different temperature and photoperiod regimes, eight cultivars of sub clover ranging in maturity from Nungarin …

Survey Of Irrigation Efficiencies On Horticultural Properties In The Peel-Harvey Catchment, S A. Milani Jan 1991

Survey Of Irrigation Efficiencies On Horticultural Properties In The Peel-Harvey Catchment, S A. Milani

Resource management technical reports

A detailed efficiency survey of about 30 per cent of the irrigated horticultural area in the Peel-Harvey catchment revealed that only two out of 20 growers operated at the recommended efficiency levels. In addition it was found that the expenses associated with inefficiency were such that 12 out of 18 farmers would be able to recover improvement costs within one year of operation.


Land Capability Study For Horticulture In The Swan Valley, J M. Campbell-Clause, Geoff Allan Moore Jan 1991

Land Capability Study For Horticulture In The Swan Valley, J M. Campbell-Clause, Geoff Allan Moore

Land resources series

The Swan Valley is an important agricultural, recreational, tourist and heritage area in which there are a number of competing land uses because of its location close to Perth. The traditional agricultural use, mainly centred around the viticulture industry, has to compete with tourist development, urban encroachment, hobby farms and clay extraction. The major objective of this report was to identify any areas of prime horticultural land which should be retained for that purpose. A land capability study was done using the existing soil series map of the Swan Valley (Pym 1955), which covers most of the Swan Valley Policy …
