Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May

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

High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.

This article describes the technique and discusses its possibilities on the Ord.

The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.

Basic Pig Breeding, P Mcnamara

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

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.

Planting And Care Of Trees In The Wheatbelt, F Batini

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

THE climate of South Western Australia includes a long summer drought which subjects trees to considerable moisture stress.

Shade trees and shelter belts can be established successfully in the wheatbelt without hand watering, provided a suitable site and variety of tree is selected and a little time is spent in site preparation and care of the young tree.

This article, which is adapted from a Forests Department publication "Catalogue of Trees for growing under Western Australian conditions", sets out the best varieties of trees and establishment methods.

Stone Fruit Regulations, W J. Hart

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

Stone fruit grading regulations were introduced for the first time recently to keep small, green or badly blemished fruit off the market. This type of fruit is always in poor demand and can spoil the prices obtained for better lines of fruit by creating the impression of heavy supplies.

Pasture Legume Varieties And Ewe Fertility, T Marshall, H. E. Fels, H. G. Neil, R. C. Rossiter

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

ALTHOUGH it was first thought that all varieties of subterranean clover would cause ewe infertility, research in the last 10 to 15 years has shown that varieties differ in potency.

The relative level of potency has also been shown to remain consistent for any one variety under normal conditions.

Dairy Beef Shows Healthy Profits, D J. Barker

Powdery Mildew Of Apples, Department Of Agriculture, Western Australia

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

Powdery mildew (Podosphaera leucotricha) markedly affects the growth and vigour of susceptible apple varieties, particularly Jonathan and Cleopatra.

The fungus survives the winter as mycelial threads in dormant buds on spurs and laterals infected the previous season. At bud-burst the mycelium grows onto the developing leaves and blossom clusters to form white patches.

Spores produced on these patches are spread by the wind onto the healthy growth.

New Varieties Could Extend The Peach Canning Season, S R J Newton

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

THE peach canning industry in Western Australia at present has only a limited period of operation, coinciding with the harvest time of the major variety, Golden Queen.

New canning peach varieties tested at Stoneville Research Station could be used to extend the harvest period of canning peaches beyond that of the present standard variety, Golden Queen.

This would have obvious advantages for growers and a canning industry.

The South African variety Keimoes was the most promising canning peach tested. Tests on other varieties are continuing.

The Control Of Annual (Wimmera) Ryegrass In Cereal Crops, Geoffrey A. Pearce, B. J. Quinlivan

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

The annual ryegrasses are valuable pasture plants in Western Australia, yet have become one of the major weed problems in cereal crops.

The key to cultural control of annual ryegrasses in cereal crops is an understanding of the factors which govern germination of the seed.

Covering the seed with soil keeps out light and provides a more stable moisture supply, bringing about a faster rate of germination. This is the basis of control programmes recommended in this article.

Recommendations for chemical control are also included.

Shothole Of Stone Fruit, Department Of Agriculture, Western Australia

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

Shothole disease is most damaging on almonds and early-flowering peaches and apricots but can also affect nectarines, plums and cherries.

The causal fungus IStigmina carpophila) survives the summer in infected buds and twig cankers.

The autumn rains then stimulate production of spores which infect other twigs, buds and subsequently the new spring growth.
