Leaflet No 1000 - Rate Of Milking With Machines - Further Results From Western Australian Herds, R. A. Bettenay

Bulletins 1 - 2999

IN an earlier article by this Department (Vol. XXVI No. 2 PP. 99-104) some introductory remarks were made on a study being conducted on the rate of milking by machine, and preliminary findings were recorded. The conclusion was reached that the rate of milking on most farms was too slow, it being considered that in the vicinity of five minutes per cow should be sufficient under machine milking and that, if the teat cups were left on for a longer period than this, damage to the udder was likely to follow.

Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.

Leaflet No 256 - Climbing Cut-Worm Or Tomato Moth (Chlorodea Obsoleta), L. J. Newman

Bulletins 1 - 2999

During the past spring caterpillars of various kinds have been unusually prevalent. In some instances they have been so numerous as to constitute a plague.

The caterpillar most in evidence was the larva of the Climbing Cut-worm or Tomato Moth.

Bulletin 118 - Pigs And Pig Raising, P. G. Hampshire

Bulletins 1 - 2999

The importance of the development of pig-raising as one of the primary industries of Western Australia cannot be too greatly stressed.

In Western Australia we have a deficiency in production of bacon and hams equal nearly £200.00 per annum. When this exceedingly profitable market has been satisfied, export markets are geographically very favourable to Western Australia pig raisers as compared to the rest of Australia.

Bulletin 119 - Take-All Of Wheat And Similar Diseases Of Cereals, W. M. Carne, J. G.C. Campbell

Bulletins 1 - 2999

This important disease, known also as Footrot, Blackleg, and Whiteheads, affects wheat principally, but also occurs on barley, rye, and certain grasses. In a very few instances it has been known to attack oats, but this is so rare that oats may be regarded for practical purposes as free from attack. Of the grasses attacked the most important, from a farming point of view in Western Australia, are Bailey Grass (Hordeum murinum), Silver Grass (Festuca bromoides and F. myuros), and the so-called Spear grasses (Bromus spp.). These annual grasses are very common in the wheat belt.

Bulletin 121 - Mildew, Septoria, Leaf Spots And Similar Diseases Of Cereals, W. M. Carne, J. G. C. Campbell

Bulletins 1 - 2999

Mildew attacks all the cereals as well as many grasses. but as in black stem rust the fungus has developed specialised races, one attacking wheat, another barley, another rye and so on, so that the form attacking wheat will not attack oats, etc

Bulletin 122 - Fruit-Fly: Description And Control, L. J. Newman

Bulletins 1 - 2999

IT is a fundamental principle of Economic Entomology that, in order to successfully combat an insect, the life history of that insect must be worked out. A feature common to all insects is a series of stages involving distinct changes of form which succeed each other in a definite order.

An insect like the fruit-fly affords no exception to this universal rule. Beginning with the fly, we have in regular succession—Egg, Larva, Pupa, and finally the fly again. These stages represent what is known as the life cycle of time insect. Each change—such as larva to pupa, pupa to fly—is …

Bulletin 104 - The Stickfast Flea, John G. C. Campbell

Bulletins 1 - 2999

The insect which forms the subject of this Bulletin has raised great consternation in certain parts of this State by the trouble which it has caused amongst Poultry.

Fleas in general are notorious on account of the discomfort which they cause to man and animals, but, in this country none has a more evil reputation than the Stickfast Flea.

Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott

Bulletins 1 - 2999

It is surprising to note the dearth of up-to-date reliable information dealing with actual results of modern windmills, under working conditions, though literature on thousands of other subjects less important can usually be obtained.

In this bulletin there is presented a complete and accurate record of the amount of water pumped daily by a windmill, under actual working conditions, for a period of 14 months.

Graded selected Pedigree seed is produced at the Chapman and Merredin Experiment Farms.

Bulletin 106 - The Red-Legged Velvet Earth Mite, L. J. Newman

Bulletins 1 - 2999

This pest is sometimes called in error the "Red Spider" or the 'Earth Flea."

It is neither a spider nor a flea, being a species of mite.

It belongs to the family of mites known as the Eupodidae and to the Genus Notophallus. Many of the members of this family are predaceous, that is, they live upon other insects or animals, but the species we are dealing with appears to be wholly a plant feeder. A popular idea is that the mite lives and breeds in the earth. The rapidity with which newly planted vegetables become infested gives good excuse …

Bulletin 105 - Pedigree Selection Of Seed At The Chapman And Merredin Experiment Farms, Geo L. Sutton

Bulletins 1 - 2999

A Paper read before the Royal Society of the Royal Society of Western Australia, 12th October,1921.

"Pedigree" or "Pure Line" selection is that system of selection under which the choice is made, not. solely because of the attractive appearance of the plant, but because of its ability to transmit its good qualities to the progeny. Such a system requires, and the method of selection ensures, that the qualities sought after shall be hereditary. For this purpose a record of ancestry is essential, hence the use of the term "pedigree."

Bulletin No 69 - The Poison Plants Of Western Australia, D. A. Herbert

Bulletins 1 - 2999

Up to the present no publication dealing with the whole of the known i)01S0fl plaits of Western Australia has been written. This Bulletin contains the collected accounts of various authors and correspondents which have been published at different times and contains a large amount of original information gathered both from field experience and from laboratory experiments. The work is not complete. A number of plants from distant districts have not been obtainable or obtainable only in amounts insufficient for exhaustive tests. These plants are comparatively few, however, and in Section 13 of this publication those which are suspected, but against …

Bulletin No 84 - Tomatoes - Their Culture In Western Australia, H. D. Larwood

Bulletins 1 - 2999

The use of the tomato has become so general during recent years that it is now in great demand as one of the most popular and wholesome articles of diet.

The plant is heat-loving, but is easily destroyed by host. In temperate regions it is seasonable during the summer months. With suitable methods an early crop can be produced several weeks earlier than the main crop, and several months before stone fruits are available; because of this the "early' crop of tomatoes is usually a most profitable one. "Early" tomatoes placed oni the market during September and October often realise …

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert

Bulletins 1 - 2999

Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

Bulletin No 80 - Cultivation Of Sugar Beet, Percy G. Wicken

Bulletins 1 - 2999

The beet belongs to the Chenopodiaceae or Salsolaceae, an order of plants which include among them many of the native saltbushes. The sugar beet (Beta vuigaris crassa) is supposed to have been developed from the wild beet (Beta vulgaris maritima), which is indigenous to the countries along the coast of Southern Europe. it is a biennial plant—that is, of two years' duration. The first year it produces a full-sized root, the second year it produces its seeds, and then dies off. Sometimes a few plants Produce seed the first year, but this is only on account of the seed being …

Guide To The Experiments In Cropping Now Running At The State Farms Of Narrogin, Merredin, Chapman, Geo L. Sutton

Grain and other field crops published reports

The publication of this Guide to experiments conducted at the State Farms is deemed desirable, in order that farmers may be made acquainted with the nature of the work and the progressive results obtained, The purpose of the alteration of practice initiated at the State Farms during the past three years is to carry on an original and definite plan for the improvement of agricultural methods, and to this end a series of experiments have been undertaken which would entail too much expense on the individual farmer, or involve a departure from his routine practice before the value of the …

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.
