Fodder Shrubs In The Murchison, D G. Wilcox

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

THE Murchison pastoral country is usually thought of as either having a perennial grass cover, as in the Wandarrie, or as Mulga country with trees and short grass.

It is easy to overlook the small shrubs which occur all over the Murchison in every type of situation, and can provide high quality feed for sheep.

Iron Chlorosis In Higher Plants As Related To The Organic Acid Content, Lucia Yulin Su

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis, which is associated with a reduction in the chlorophyll content of leaves, is a major problem in the growing of deciduous fruit trees and some field crops on Western soils (16). For the deciduous fruit and field crops the predominant chlorosis pattern is the iron deficiency type which on Western soils is associated with high bicarbonate concentration in the soil.

Use Of Gamma Radiation, Chemicals, And Packaging Films To Control Post Harvest Diseases And To Extend Refrigerated Life Of Strawberries And Cherries, Gerald M. Cooper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years there has been a considerable amount of work done on developing chemicals that would inhibit mold growth when applied to fresh fruit, and at the same time, be acceptable to man when taken orally. This would save many thousands of tons of fresh produce that are lost each year by spoilage before it ever reaches the consumer. Along with the development of new chemicals to inhibit mold growth there is a substantial amount of research being done on developing a packaging film that will prevent recontamination of the produce, at the same time allowing the passage of …

Embryo Sac Development Of An Intergeneric Hybrid Between Lycopersicon Esculentum Mill. And Solanum Lycopersicoides Dun., Ray William Bills

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the search for sources of resistance to the curly top virus disease of tomatoes (Lycopersicon esculentum), it was found by some investigators that certain species of the genus Solanum express an apparent immunity to the disease. It would be desirable to transfer the resistance expressed by the genus Solanum into the genus Lycopersicon. The major problem to the plant breeder becomes one of obtaining a compatible F₁ hybrid between the Lycopersicon and Solanum genera through which genes controlling resistance may be transfered to Lycopersicon. In 1951, C. M. Rick reported a successful cross between …

The Control Of Grasses With Chemicals, G R W Meadly

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

GRASSES are among man's greatest assets and usually he tries to encourage their growth.

The cereals, rice and many other grasses supply him with basic items of food and they are also important components of pastures which provide grazing for sheep and cattle.

Organic Manures In Commercial Vegetable Growing, T Wachtel

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

AT one time organic manures provided the only means to return the plant nutrients into the soil, which were removed by cropping.

With the rapid increase of mechanisation, these materials have become very scarce, and their cost extremely high.

It is, therefore, necessary to consider whether the benefits gained from their use are sufficient to warrant their high purchase price, or indeed whether the use of manures is warranted at all.

Orchard Drainage, R G. Cahill

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

UNDERGROUND drainage of orchard land is an essential feature of fruitgrowing which is overlooked by many orchardists.

Soils should be adequately drained to cope with all winter rains.

Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett

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

A DECLINE in carrying capacity has occurred in large areas of the Pilbara district of the North-West, due to the decrease in palatable plants and the increase in unpalatable ones.

The relative palatability of the various species to sheep is therefore a matter of considerable importance to pastoralists.

Root Lesion Eelworm (Pratylenchus Penetrans) In Vegetables, O M. Goss

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

Castor Beans : Ricinus Communis Linn, T Pavy

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

MANY people have seen the wild castor oil plants around the metropolitan area, growing in rubbish dumps, and waste lands.

But they have not realised that the demand for castor oil has been increasing over the last 15 years.

Although one of its main uses is in the lubrication of jet engines, it is also used in plastics, special low temperature lubricants, hydraulic fluids, paints, varnishes, textiles and pharmaceutics.

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

Chemical Poisoning In Animals. 3. Prussic Acid, H D. Seddon

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

HYDROCYANIC or prussic acid poisoning is a serious and not uncommon ailment of ruminants, and may be a cause of rapid death when pasture plants capable of developing dangerous levels of the poison are being grazed.

Potassium Deficiency In Medium Rainfall Areas, William John Toms

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

IT is well known that potassic fertilisers must be used for the successful growth of subterranean clover (Trifolium subterraneum L.) on many soils in the higher rainfall districts of Western Australia.

Recent investigations have shown that some soils in medium rainfall districts are also too low in potassium to grow healthy subterranean clover pastures.

Strawberry Culture, K T. Whitely

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

WHETHER fresh or preserved, the strawberry finds universal favour and is regarded more or less as a luxury.

For the grower it offers the quickest cash return of all fruits, cropping in the first year. It is, therefore, very useful to a man trying to establish a fruit growing property with limited capital.

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

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

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.

Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.

A Study Of The Effects Of Different Substrates On Growth And Reproduction In Certain Coprophilic Agaricaceae, Raymond C. Brown

Theses and Dissertations

Psilocybe mutans sp. nov. had ceased fruiting consistently in artificial culture several years prior to the initiation of this study. In the couse of this study fruiting bodies were produced on a number of different substrates. All cultures were inoculated by mycelial transfer or by spraying with a suspension of pre-germinated spores. All cultrues were incubated for one to two weeks in a constant-temperature room at 70°F. on a shelf fourteen inches below a fluorescent lighting fixture. Lighting was continuous with an intensity at shelf level of approximately 3,000 foot-candles. Fruiting on any particular substrate was improved if the substrate …
