New Varieties Top 1967 Yield Tests, H M. Fisher

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

LARGE gains can result from using improved cereal varieties and in recent years activity in breeding varieties adapted to local conditions has increased.

The varieties available and their suitability for different areas and conditions need constant review.

Papaw Varieties For Carnarvon, Michael Gregory Hawson, D. W. Thomas

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

PAPAWS grow very well in the Carnarvon area of Western Australia and throughout the north of the State.

Some produce quite well as far south as Perth.

The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer

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

ROSE CLOVER is being produced and used in increasing quantities in south-western Australia. The first line named was designated Kondinin and five lines have now been given cultivar (variety) names.

One of the first samples of rose clover, C.P.I. 13949, introduced into Western Australia proved to be a mixture of two very similar types, differing visibly only in leaf markings.

The mixed sample was named Troodos,* and the selection from it, Olympus.

This paper describes the origin of the two varieties, their history and characteristics.

New Strains Of Subterranean Clover : Prospects And Problems For The Seed Producer, B J. Quinlivan

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

THREE new strains of Subterranean clover—Daliak, Seaton Park and Uniwager—have been released.

In Western Australia, in other States and perhaps some overseas countries, the next few years will see many farmers or graziers summing up the merits and demerits of these strains and subsequently making a decision to change or not to change their present strains.

Wheat Diseases In Western Australia, W A. Shipton, W. R. Tweedie, K. J. Locke

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

DISEASES caused by pathogenic organisms can seriously affect the yield of wheat. Some diseases are comparatively rare whereas others occur over a large area of the wheatbelt year after year.

Canberra Creeping Lucerne Outyields Hunter River In Denmark Trial, F E. Ryan

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

LUCERNE is successfully grown as a fodder crop in high rainfall areas in Western Australia without irrigation and there is scope for expansion.

Establishment problems can be largely overcome by choice of a well drained site, spring planting to avoid weeds and pests, an application of 1 ton of limestone to the surface 5 to 6 inches of soil before sowing, and sowing of innoculated and pelleted seed.

Watsonia (Watsonia Spp. And Chasmanthe Aethiopica (L.) N.E. Brown), G R W Meadly

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

AS the t i t le implies, the vernacular name Watsonia is applied, not only to several species of that genus, but also to the related Chasmanthe aethiopica. At times some small flowered types of Gladiolus are also included.

Subterranean Clover Establishment In The Wheatbelt, M L. Poole

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

Care and attention to detail will greatly increase the chances of establishing good subterranean clover pastures in the wheatbelt.

PASTURE ESTABLISHMENT usually takes second place to cropping in the wheatbelt, with many farmers "bunging in a bit of clover" and hoping for the best. The worst often transpires, with either patchy stands or complete failure resulting.

Using "cheap" methods of establishment is a short-sighted approach and a waste of energy and resources.

Identifying The Grain Of Barley Varieties In Western Australia, J L. Mcmullan, H. M. Fisher

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

THE identification of varieties of plants depends on the existence of a number of visual characters which have recognisably different forms in different varieties, but are relatively unaffected by environmental conditions.

For many species the characters of the whole plant may be required to arrive at a satisfactory identification and seed must be grown and the resulting plants compared with known varieties.
