Nodulation Of Legumes On New Light Land. 3. The Effect Of Rogor Seed Treatment On Legume Nodulation, O M. Goss, W. A. Shipton

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

SEED treatment with systemic insecticides is widely used for the control of insect pests. However, when seed inoculation is necessary for pasture establishment, seed treatment with insecticide is not advisable.

A field experiment conducted at Badgingarra Research Station in 1964 showed that the systemic insecticide Rogor was very damaging to the applied rhizobia even when the treated seed was held for a month before inoculation.

The Control Of Weeds In Orchards, Geoffrey A. Pearce, S. E. Hardisty

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

THE use of herbicides for the control of weeds in orchards has become established during the past few years.

It has become more efficient with the introduction of newer herbicides which have proved more effective and less dangerous than some of those recommended in the past.

The Starling, John L. Long

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

Despite their pretty colour and their song, starlings cannot be considered beneficial, especially in the fruit and grain-growing areas of W.A. where they are declared vermin.

MILLIONS of starlings inhabit the settled parts of eastern and south-eastern Australia, but so far they have not reached Western Australia.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

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

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

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.

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.

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.

Insect Pests Of Cotton In The Ord River Irrigation Area, K T. Richards

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

COTTON is grown in the Ord Valley of north Western Australia, mainly as an annual, irrigated crop during the hot summer months of the "wet season".

It is usually planted in November-December and harvested March-May.

This period of growth corresponds closely to that of maximum insect activity.

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

RESULTS of 1963-64 linseed variety trials are available for four trials on research stations and for four trials on farmers' properties.

These are shown in the table below. Excellent yields were obtained at some sites, while disappointing results were obtained at Chapman and Esperance.

Poor results at Esperance were due to the poor finish to the season.

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

The number of wheat tillers affected by take-all was not influenced by the application of ammonium sulphate in an experiment at Esperance Downs Research Station.

However, its use stimulated tillering and increased yields by an estimated 7.4 bushels an acre.

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

WEST of Dandaragan and the Midland line from Watheroo to Mingenew there are four million acres of scrubplain commonly called the Western Sandplain.

All virgin soils in this region are acutely nitrogen deficient so that the agricultural future of the region depends on how successfully legumes are grown.

Dry Season Rice Varieties For The Ord River Valley, A L. Chapman, P. J. Van Rijn

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

PREVIOUS experimental work at the Kimberley Research Station (Langfield 1961) showed that, in general, indica varieties of rice are best adapted for wet-season sowing and japonica varieties for dry-season sowing.

This article gives the results of three rice variety and time of planting experiments carried out at Kimberley Research Station in the I960, 1961, and 1962 dry seasons. The recommendation is to sow the variety Caloro during May.

Stem Rust Of Wheat, H L. Harvey

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

STEM RUST is one of the most serious diseases of wheat and is of world-wide importance.

Fortunately, widespread epidemics are rare in Western Australia because the general climatic conditions are usually unfavourable to the disease.

Nevertheless, localised outbreaks of stem rust are quite common on the Esperance Plains and around Geraldton where seasonal conditions are frequently mild and humid.

The 1963-64 Wheat Stem Rust Epidemic, J T. Reeves

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

Comments on the 1963 epidemic and the current situation regarding rust races and resistant varieties in Western Australia.

THE 1963-64 harvest included 12 million bushels of undergrade wheat, representing 25 per cent, of the total harvest.

The average yield was reduced to only 11.3 bushels per acre. Although these adverse effects were due to a number of causes, the principal one was stem rust.

The economic loss due to this disease in the 1963-64 harvest probably exceeded £10 million.

Inoculation And Lime-Pelleting Of Leguminous Seeds, W P. Cass Smith, Olga M. Goss

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

IN Western Australia extensive areas of new land are brought under cultivation each year.

Much of this virgin soil is only sparsely populated with the beneficial rhizobial bacteria which nodulate the roots of common pasture and forage legumes, such as subterranean clover, barrel medic, lucerne and field pea.
