Robinia : The False Acacia, Robert Dunlop Royce

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

ROBINIA, the false acacia, is a tree up to 60 feet high, and is native to the eastern United States.

There it develops a trunk 3 or 4 feet in diameter and produces a hard close grained and durable timber.

In America it is known as black locust or simply as locust.

Plant Nutrition In Western Australia, George Henry Burvill

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

PLANT nutrition is of great practical importance in Western Australia.

Without a well developed fertiliser industry and research and experiments to guide farmers in appropriate fertiliser use the State's agriculture would be very restricted.

Root Knot Eelworm And Its Control, O M. Goss

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

ROOT galling caused by root knot eelworm attack is very common in the lighter sandy soils of Western Australia.

This parasitic worm causes severe unthriftiness which may even result in the death of the plant, particularly during the summer months when the disease is most damaging.

Root knot eelworm has a wide host range.

Weed Control : Cotton Fireweed, Department Of Agriculture, Western Australia

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

COTTON FIREWEED is a native perennial plant which has developed as a serious weed in the south coastal areas.

Being a perennial it makes quick, active growth following summer rains and rapidly outgrows annual pasture plants.

The Effect Of Seaweed Meal On Yolk Colour, B R. Vale, P. Smetana

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

Could seaweed, plentiful on local beaches, be used to improve egg yolk colour?

This article gives the results of experiments at the Department's Poultry Research Station.

Wheat Quality Surveys In Western Australia. 2. Variation Between Seasons And Localities In The Production Of High And Low Protein Wheat, J A. Parish

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

Although the protein content of West Australian f.a.q. wheat averages only 9.4 per cent., often substantial amounts of comparatively high protein wheat are contained in this mixture.

However the quantity varies widely from year to year and is obtained from widely scattered areas of the wheatbelt.

Dairy Farming In The Busselton-Margaret River District. Part 4. Pasture Production, R A. Bettenay

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

If deteriorated pasture and underdeveloped pasture in the Busselton-Margaret River district could be improved to the standard of the present highly productive pastures stocking rates could be improved by more than 50 per cent.—final article in a series reporting the results of a survey of farm practices in the district.

Root-Bound Shrubs, Department Of Agriculture, Western Australia

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

THE illustrated garden shrub (Cotoneaster) strangled itself with its own roots.

When purchased several years earlier it had been in the pot too long and the young roots, not being able to grow straight down had spiralled round and round in the pot.

Stinkwort (Inula Graveolens Desf.), G R W Meadly

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

THE original home of stinkwort is the Mediterranean region, including northern France. Apparently the first Australian record was at Onkaparinga in South Australia about 90 years ago.

Efforts were made to keep it in bounds during the years immediately following introduction, but it continued to spread and is now f i r m ly established in all agricultural districts of South Australia.

It also covers large tracts of land in New South Wales and Victoria and occurs in most districts of Western Australia.

Gorteria : A Recently Recorded Weed, Department Of Agriculture, Western Australia

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

A NUMBER of our major weed pests including Cape t u l ip and double gee are native to South Africa.

It is not surprising, therefore, that Gorteria, recently recorded for the first time in Western Australia, also comes from that country.

The Naturalised And Cultivated Annual Medics Of Western Australia, B J. Quinlivan

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

IT is not many years since the term pasture improvement in Western Australia was synonymous with one species only, subterranean clover.

The amazing adaptability of this species to the environment enabled it to be grown in a wide range of rainfall conditions and in many different districts.

Time Of Lambing At Esperance, R J. Doyle

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

ESPERANCE is one of the few places in Western Australia at which experiments over three years have shown a definite improvement in number of lambs produced to marking, as a result of lambing in the August-September period.

Herbicides For Firebreaks, Geoffrey A. Pearce

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

IN recent years, great interest has been shown in the possible use of chemicals for creating firebreaks as an alternative to cultivation.

The advantages are obvious, and suitable treatments are available; the main deterrent at the present time is cost.

Kimberley Research Station Progress Report, 1964 : Oil Crops, D F. Beech, M. J. T. Norman, W. R. Stern

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

INVESTIGATIONS on the adaptation of a range of oil crops to the Ord River environment have been in progress since the early years of the Station.

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

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

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.

Kimberley Research Station Progress Report, 1964 : Insect Pests And Insecticides, K T. Richards

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

FOR the past four years, detailed studies have been carried out in regard to the identification, status, bionomics, and control of insects and mite pests attacking the various crops grown in the Ord River Irrigation Area.

Molybdenum Increases Cereal Yields On Wheatbelt Scrubplain, R J. Doyle, R. J. Parkin, J. A. C. Smith, J. W. Gartrell

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

IN four field experiments and two paddock strip trials since 1960, molybdenum applied to wheat and oats grown on scrubplain soils in the eastern wheatbelt increased yields by up to 3 i bushels of wheat and 5^ bushels of oats per acre.

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

Suggested controls for two persistent weeds.

A Herbicide For Native Poison Plants, Department Of Agriculture, Western Australia

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

THE usual method of killing poison plants is by a programme of ploughing, cropping and burning.

The burning not only destroys a proportion of the plants, but stimulates the germination of dormant seeds, which otherwise would remain in the soil in a viable condition for many years.
