Making Horticulture Sustainable, Bob Paulin, Neil Clifton Lantzke, Ian Mcpharlin, Murray Hegney Jan 1995

Making Horticulture Sustainable, Bob Paulin, Neil Clifton Lantzke, Ian Mcpharlin, Murray Hegney

Journal of the Department of Agriculture, Western Australia, Series 4

Sweet crunchy carrots, luscious strawberries at very reasonable prices, crisp green vegetables - these are just a few of the horticultural products that Western Australians take for granted and eat almost every day. But is their future availability guaranteed as population grows, suburbia spreads and environmental concern increases?

Storm : [Wind Erosion In The Great Southern], Dan Carter

Journal of the Department of Agriculture, Western Australia, Series 4

On Thursday 11 May 1995, a low pressure system with central barometric pressure of 990 hPa formed of south-western Australia. This depression directed gale force winds over the South-West Land Division for some seven hours.

Dan Carter reports on the widespread damage to soils and property, and management practices that would have reduced the problem.

Proline Concentration As An Indicator Of The Level Of Salt Tolerance, Philomena Y. Rosalie Jan 1995

Proline Concentration As An Indicator Of The Level Of Salt Tolerance, Philomena Y. Rosalie

Theses : Honours

Each year approximately 20 million hectares of land become affected by increasing salinity. Salt tolerant plants are being used to rehabilitate salt affected areas. Plants use a variety of mechanisms to adapt to salt in their environments. Glycophytes tolerate low to moderate levels of salt while halophytes can tolerate very high salt levels. Many basic physiological attributes have been suggested as important components of a salt tolerant phenotype. These include, influx and/or efflux of ions across plasma membrane and the tonoplast, modification of membrane composition and synthesis of compatible solutes such as soluble carbohydrates, glycine betaines and proline. The project …

Viticulture research reports

A course run by the Department of Agriculture, Western Australia, August 1995.

The purpose of this publication is to clarify the role fertilisers play in commercial table grape production and to detail methods of selecting fertilisers. This selection process however is not easy as there are over 600 registered fertilisers in Western Australia.

In deciding which is the best fertiliser for a particular property many factors have to be considered. These include:

* Age of vine

* Rootstock

* Variety of table grape

* Soil type

* Soil chemistry

* Irrigation methods

* Previous fertiliser history Previous yield, vigour and …

Grain and other field crops published reports

Grain legumes

- Chickpea

- Field pea

Canola essentials:

Site selection -Paddock selection is critical for a successful canola crop. Avoid paddocks with waterlogging, wind erosion and broadleaf weeds - particularly wild radish, turnip, mustard and doublegees.

Soil type - Canela grows well on most soil types, however it prefers well drained gravel soils, red loams, sandy _loams and deeper duplex soils. Soil pH levels (in CaCl2) of 4.5 to 8.0 are suitable. Soil test paddock for pH, phosphorus, and potassium levels.

Rotation - Grow canola after manipulated pasture, lupins or other grain …

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia Dec 1994

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia

Animal production and livestock published reports

A seminar and workshop was held at Fitzroy Crossing in October 1993 to address the consequences of flooding to landholders and communities.

Damage to flood plain fencing was identified as one of the major concerns to landholders.

An outcome from the workshop was the decision to draw on local knowledge and collate information on options for fence and floodgate designs.

This information was to be made available to land holders and other interested parties - hence this publication.

Imbibition Response Of Winter Wheat To Water-Filled Pore Space, Guillermo A. Studdert, Wallace Wilhelm, James F. Power Nov 1994

Imbibition Response Of Winter Wheat To Water-Filled Pore Space, Guillermo A. Studdert, Wallace Wilhelm, James F. Power

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Reduced temperature and increased bulk density associated with conservation tillage systems cause lower seed germination, seedling emergence, and early growth rates resulting in reduced plant stands. Prediction of the influence of soil condition on seed imbibition through simple soil measurements would help make agronomic decisions such as planting date and/or density. Our objectives were to evaluate the influence of soil water-filled pore space on winter wheat (Triticum aestivum L.) seed imbibition and to assess the possibility of describing the relationship through simple mathematical models. We measured the rate of water uptake by heat-killed wheat seeds at three levels of …

Floristic Survey Of Northern Sandplains Between Perth And Geraldton, Edward Arnold Griffin Aug 1994

Floristic Survey Of Northern Sandplains Between Perth And Geraldton, Edward Arnold Griffin

Resource management technical reports

A database of plant lists from over 2,500 sites was compiled from the the Northern Sandplains between Perth and Geraldton. Over 2,500 plant taxa were recorded from the area. Preliminary classification revealed in the order of 500 different floristic types. Analysis of these demonstrated strong regional patterns of floristic composition related to geology and soils. Consistencies in these patterns indicated a need to review the location of some of the botanical district boundaries.


Patterns Of Isozyme Variation In Relation To Population Size, Isolation, And Phytogeographic History In Royal Catchfly, Rebecca W. Dolan Aug 1994

Patterns Of Isozyme Variation In Relation To Population Size, Isolation, And Phytogeographic History In Royal Catchfly, Rebecca W. Dolan

Scholarship and Professional Work - LAS

The distribution of genetic variation within and among plant populations is influenced by both contemporary and historical factors. I used isozyme analysis of band phenotypes to examine genetic structure in the rare prairie forb Silene regia. Relationships between current-day population size, isolation, and phenotypic variation were assessed for 18 populations in two regions with differing postglacial history. Western populations from unglaciated southern Missouri and Arkansas were more genetically diverse based on the Shannon-Weaver index (H) and a polymorphic index than were more eastern populations. These differences may be due to loss of variation with repeated founding of new populations in …
