Chemical Poisoning In Animals. 4. Phosphorus, H D. Seddon

Although it has now been largely replaced, it is still an important cause of accidental death by poisoning.

Weed Problems In The Kimberleys, Rijn P J Van

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

AFTER fifteen years of irrigated agriculture, weeds have become a major problem at the Kimberley Research Station.

Since the Station is regarded as a type location for the potentially irrigable areas of the Ord River Valley, a similar problem is expected to arise when the surrounding areas have been under several years of commercial cropping.

An intensive study of weeds was therefore initiated at the Research Station in 1960.

Better Peach Varieties, Frank Melville

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

The PEACH is a very versatile fruit and a universal favourite. It is surprising then that the area of peaches in this State is very little different today to what it was 15 years ago. This is in spite of the fact that the population has increased by 48 per cent.

New peach varieties now under test could help satisfy the consumers' demand for a better range of high quality eating peaches— and expand the market for peaches in Western Australia.

Fourth West Australian Random Sample Egg Laying Test : 1960-1961, P Smetana, F. A. E. Hunt

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

TO help improve the quality of laying stock for poultry farmers in Western Australia the Poultry Branch of the Department of Agriculture conducts annual random sample egg laying tests.

The tests reveal good and bad points in the laying strains available, and their results are a valuable guide to breeders.

Most of the chickens sold in Western Australia are now bred by hatcherymen who participate in the Random Sample Tests.

Tests For The Determination Of Milk Quality, H Maslin

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

Stilling Coastal Sand Drifts With Marram Grass, J L. Mcmullan

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

DRIFTS in dunes on the coast between Albany and Geraldton may be stabilised by planting marram grass (Ammophila arenaria).

However, it should be anticipated that much of the planted grass will die before an area is finally stabilised.

Chronic Respiratory Disease Of Poultry In Western Australia, M R. Gardiner, R. V. Vagg

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

Widespread chronic respiratory disease was revealed in a survey of respiratory infections in Perth metropolitan area poultry flocks.

Most occur in early or midsummer and cause a serious fall in egg production. Return to full lay after the infection is usually slow.

While these infections can cause production losses in flocks which are under heavy stress, none of the more serious forms of chronic respiratory disease was found.

This gives encouragement for future control of the disease in Western Australia.

Chick Management, D F. Hessels

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

A UGUST is the month when most poultry farmers get their chickens. Special attention will be needed in the coming weeks, with nutrition and disease prevention the main considerations.

Skim Milk : The Cheapest Pig Feed, P C. Beck

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

BUTTERFAT production has started on most South-West dairy farms, and although pig prices are not high at present, many dairy farmers have either purchased young stock or bred pigs to utilise their surplus skim milk.

Skim milk is the best feed for pigs on the dairy farm. Properly used in conjunction with other feeds it produces high quality carcasses at minimum cost.

Rechauffe : Polite Name For Rehash, M L. Paul

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

ALTHOUGH every housewife tries to serve fresh foods, she often has food left over from the family meal.Rather than waste this food, she will reheat it for another meal.

This reheating of food is necessary to prevent waste, but freshly cooked foods are, of course, to be preferred from every angle for nutrition, flavour and appearance.

Delayed Foliation In Apple Trees, J E L Cripps

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

DELAYED foliation refers to the late leafing out and production of small leaves by fruit trees.

However, the weak and protracted blossoming which precedes the appearance of the leaves has more serious consequences for it may lead to a reduced set of fruit.

Yellow Dwarf Disease Of Cereals, H L. Harvey

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

YELLOW dwarf, caused by the barley yellow dwarf virus (Oswald and Houston 1951) was recorded in this State for the first time last season.

There is reason to believe that this disease has been present for some years but in the past its symptoms have been confused with various environmental and nutritional disorders.

Successive Crops In A Clover Ley Rotation, H M. Fisher

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

Recent investigations suggest that cereal production on clover leys in the medium rainfall region can be increased by growing a succession of cereal crops after the pasture phase.

In most areas accumulated fertility after four to five years of clover pasture will support two, and in some cases three, high yielding cereal crops grown in succession.

Where root rot diseases are prevalent it is an advantage to sow oats as the initial crop.

Water For Agriculture. 2. Plants For Salty Water, C V. Malcolm

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

However, in Western Australia many natural water supplies contain harmful amounts of dissolved salts.

Water For Agriculture. 3. Watering Plants With Salty Water, Stanley Thomas Smith

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

In Western Australia it is often necessary to use saline water for irrigation and gardening because of the lack of better water.

Two factors influence the results achieved. One is the selection of suitable plants, the other is the way in which the water is used.

Trees Of Western Australia. No. 99. The Mottlecah (Eucalyptus Macrocarpa Hook.). No. 100. The Bald Island Marlock (Eucalyptus Lehmannii Preiss Ex Schau.), Charles Austin Gardner

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

This species, a shrub between six and 15 feet in height, is the largest-flowered of all the species of Eucalyptus.

The name is intended to indicate this fact, but unfortunately the Greek work makros means "long" and actually the fruit "karpos" is remarkably short in comparison to its diameter, being in fact the broadest fruit within the genus.

Rearing Healthy Calves, Department Of Agriculture, Western Australia

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

NOW is the time to consider some form of grazing management and supplementary feeding for early born calves, especially in the butterfat zone.

The calves are now two to three months old and beginning to forage for themselves, This can be a critical period in their development.
