Lupins In Western Australia. 2. Cultivation Methods, John Sylvester Gladstones

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

While lupins are by and large plants of lighter and less fertile soils, important differences exist among them in their soil preferences.

There may also be some differences in climatic requirements. Present knowledge of these differences is summarized in the Table below.

Linseed Production Survey : Esperance, 1968, R J. Guyton

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

A SURVEY conducted after the 1967 linseed season found that although most farmers understood the requirements of linseed growing there were several crop failures. These were associated with time of planting, soil type and insect control measures.

The Esperance district office of the Department of Agriculture conducted a second survey during December, 1968 and January, 1969

Paspalum Vaginatum : For Salty Seepages And Lawns, C V. Malcolm, I. A. F. Laing

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

PASPALUM VAGINATUM, aptly termed "sea shore paspalum" has an amazing ability to thrive in wet salty situations. It is also a good lawn grass.

Seed of the grass is not available but it may easily be established by planting pieces.

This article reviews where and how the grass may be used.

The Long Term Effects Of Frequent Cropping, Stanley Thomas Smith

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

AGRICULTURALLY speaking, few Western Australian soils are more than 50 years old. We have the responsibility of preserving them for farming—not for one man's lifetime, but for centuries.

The aim of this article is to demonstrate that cropping and cultural practices do have some effects on the soil, and that these effects should be considered when choosing a farm rotation.

Wildflowers Of The Stirling Range, Alexander S. George

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

TWO hundred miles south-east of Perth, the Stirling Range rises abruptly from the surrounding plain. About forty miles long, it is a line of semi-isolated hills, rather than a continuous block.

There are many intriguing plants of diverse colour and form. Well over 400 species are known from the Range. A number of these are found no-where else, and some are restricted to one mountain.

The Control Of Weeds In Cereals, Geoffrey A. Pearce

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

PRACTICALLY all broadleaved weeds found in cereals can now be killed with herbicides and with most, the farmer has a choice of chemicals.

Two more new products are now available and these have several advantages over other herbicides.

Pasture Establishment In The Wheatbelt, M L. Poole

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

The value of legume based wheatbelt pastures is so great that considerable care is warranted during their establishment. Without such care patchy establishment or even complete failure is likely to occur.

IN THE WHEATBELT too many farmers still put less effort into their seeding of pasture species than their seeding of crops.

This may be because both compete for the farmer's time in the busy seeding period and it is the cereal crop which possesses the obvious cash value.

However, the total value of a good pasture has to be assessed over a period of several years because of its …

Continuous Cropping Trials, M G. Mason

Experimental Summaries - Plant Research

The aims of the trials at Binnu, Chapman, Wongan Hills, Avondale and Merredin were:

1. To determine whether the application of nitgrogen and fertilisers can maintain yields under a "continuous cropping" system
2. To compare the merits of three sources of nitrogen for this purpose.
3. To determine the maintenance dressing of superphosphate under this system and the need for supplementary fertilisers.

Trial 61A2
There have been no great problems with this trial. for a number of years the plots have required chemical spraying to control wild oats which had built up. In 1968 and 1969 some plots were soil sampled to determine …

Chemical Firebreaks, Geoffrey A. Pearce

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

MANY public bodies are making regular use of herbicides to create firebreaks. In Western Australia more than $200,000 is being spent on chemicals each year to protect property from fire.

In many situations where the buildings and property are of great value, the cost of the chemical becomes insignificant.

Nitrogen Use On First Crops After Legume Pasture, M G. Mason

Experimental Summaries - Plant Research

Apart from the normal factors affecting response of cereals to nitrogen fertilizers, i.e. length of growing season, rainfall, soil type etc, there are other factors which affect the response after a legume pasture. these factors include length of the previous legume phase and how good was the stand of legumes. Unfortunately for most of the trials in the past, involving the use of nitrogen on first crops after legumes, this information is not available.

Soil And Tissue Testing For Potassium., Department Of Agriculture And Food, Western Australia

Experimental Summaries - Plant Research

No meaningful conclusions can be drawn until the multiple regression analysis comparing soil and plant parameters with level of response has been completed. Similarly it is extremely dangerious to extrapolate results obtained from any one experiement in a particular district to the general farm situation. In addition these results represent only 1 rather atypical season and so need to be verified by additional calibration trials. in 1973 (40) and 1974 (20).

The Fate Of Nitrogen In N-P Compound Fertiliser Urea And Ammonium Nitrate., M G. Mason

Experimental Summaries - Plant Research

Trial: 69WH4

Aim of Trial : to follow the movement of nitrogen in the soil and to follow the chemical changes of the nitrogen applied as N-P compound 24 :24, urea and ammonium nitrate. Also to follow the pattern of uptake of this nitrogen by the plants. To compare the effects of these fertilisers on the yields of wheat and to relate differences to changes in the nitrogen fractions in the soil and to nitrogen and phosphorus in the plants.

Time Of Application Of Solid Nitrogen Fertilisers., M G. Mason

Experimental Summaries - Plant Research

The current recommendations for time of application of soild nitrogen fertilisers such as urea, ammonium nitrate and sulphate of ammonia are:

Zone A: These fertilisers should be applied as close to seeding as possible.

Zone B: As for zone A except on very sandy soils which are very prone to leaching, where application can be delayed 2-3 weeks.

Zone C: Applications should be delayed about 3 weeks after seeding.

Fertility Build-Up In Wheatbelt Soils, M D. Carroll

Progress In Weed Control, Department Of Agriculture, Western Australia

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

In May, 1967, the "Journal of Agriculture" printed a special issue on weed control, with the emphasis on chemicals for weed control in cereal crops.

This month, just two years later, enough new information has accumulated to warrant publication of another "theme" issue, this time with important articles on weed control in pastures, chemical firebreaks and chemical ploughing, as well as weed control in linseed and cereal crops.

Pasture Improvement In South Western Australia, J W. Malcolm

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

"There is no doubt that Australia's enhanced prosperity in the last 30 years has been dependent in no small measure on the use of legume-based pastures." E. M. Hutron, June, 1968. *

THE LAST 30 years have seen an increased interest in pasture improvement which has transformed much of Western Australia. Large areas have been sown to new and improved pasture species—as a result productivity of both livestock and cereal enterprises has risen.

Pastures For The Pastoral Areas, D G. Wilcox, K. Fitzgerald

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

The pastoral areas lie generally outside the zone where cultivated crops are grown.

The rainfall is erratic and the basic pastures for sheep and cattle consist of native plants.

In some favoured areas however, and in particular situations, sown pasture species are becoming increasingly important.

Saltland Pastures, C V. Malcolm

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

FOLLOWING THE DEVELOPMENT of Agriculture in Western Australia considerable areas of highly productive land have become salt affected to the degree that normal crops and pastures cannot be grown.*

However, species and establishment methods are available which can bring at least some of this land back into production.

Promising Results On West Kimberley Pindan Country, A L. Payne

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

IN the 22 to 28 inch rainfall belt of the West Kimberley area of Western Australia are extensive areas of what is locally known as "pindan" country.

The term "pindan" refers to a light red or yellow sandy soil type supporting scattered Eucalypts, sparse-dense wattle scrub and grasses such as curly spinifex, ribbon grass and native sorghum.

Legumes Or Artificial Nitrogen?, N J. Halse

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

Choosing between legumes and artificial nitrogen is not the problem which many farmers are making it.

This article deals with the choice in the mixed cereal and sheep farms of the Western Australian wheatbelt.

Ammonium Nitrate Vs Urea, M G. Mason

Experimental Summaries - Plant Research

Ammonium nitrate is a source of nitrogen containing half

its nitrogen in the ammonium form and half in the nitrate form.

Some properties are set out in comparison with urea in the

following table.

Ammonium nitrate has an advantage over urea in that it can

be topdressed onto the surface of the soil and left uncovered

without a danger of loss of nitrogen to the atmosphere. When urea

is left uncovered on the surface of the soil losses of nitrogen occur

through volatilisation of ammonia during the hydrolysis of the urea.

Such losses with ammonium nitrate are only likely to …

Honey Plants In Western Australia, F. G. Smith

Bulletins - 3000 - 3999

Successful honey production depends, among other things on a good knowledge of the plants which produce nectar.

Every apiarist needs to know which plants are of importance to honey-bees, where those plants occur, and when they flower. He also needs to know which plants produce nectar which will result in the production of good quality honey, and which produce unpalatable or unmarketable honey. To maintain the strength of his bee colonies he also needs to know which plants produce nutritious pollen.

The object of this bulletin is to provide the basic information on these subjects in the main beekeeping areas …

Isolation And Partial Characterization Of The Toxic Substance From Eremocarpus Setigerus Benth, Shuliang Lee

Loma Linda University Electronic Theses, Dissertations & Projects

The work on the active substance of Eremocarpus setigerus Benth has been previously performed by Naito and Noller. However, the investigation was not complete. Therefore we isolated and tested this substance by steam distillation and thin layer chromatography technique. A yellow sticky toxic substance was isolated with Rf values of 0.15 in benzene system and 0.57 in benzene-absolute ethanol (95:5 v/v) system.

The toxic substance which is free of halogen, nitrogen, and sulfur, is soluble in ethyl ether, ethanol, and concentrated sulfuric acid. It has a maximum absorption in the ultraviolet region that indicates the presence of unsaturation. Its infrared …
