Rates Of Superphosphate For Pasture And Crop Production In The Salmon Gums District, R N. Glencross, W. J. Cox

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

DURING the last few years large areas have been released for cereal and pasture production in the southern part of the Shire of Dundas and the northern part of the Shire of Esperance.

Changes in land use since 1962 are summarised in Table 1.

The Dalmation Green Graft, D Mann, H. R. Rodda

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

THE GREEN GRAFT, introduced to the Swan Valley by Dalmatian vignerons many years ago, is carried out in late November or early December, at the stage when the pith of the growing shoot is beginning to whiten.

Because stock and scion are green at this time and the shoots have not started to ripen, the green graft calluses quickly.

Bussell Barley, J L. Mcmullan, J. A. Parish, H. M. Fisher

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

BUSSELL is a new high yielding 2-row barley variety named early in 1967.

An early maturing variety, with white grains of good quality, Bussell has short and extremely strong straw.

It has yielded more than any other variety under test in areas of Western Australia which receive more than 18 inches of annual rainfall.

It has yielded more than Prior in all areas.

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.

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.

West Midlands Development : Poison Plants In The West Midlands, T E H Aplin

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

TOXIC plants have caused considerable economic loss to stock raisers since the early days of settlement in Western Australia.

Although much is now known of the toxic materials contained in such plants, and although most of the plants have been thoroughly publicised, losses are still occurring in many areas.

Poison Plants Of Western Australia : Crinkle-Leaf Poison (Gastrolobium Villosum Benth.), Runner Poison (G. Ovalifolium Henfr.), Horned Poison And Hill River Poison (G. Polystachyum Meissn.), Woolly Poison (G. Tomentosum C.A. Gardn.), T E H Aplin

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

THIS article deals with four toxic species of the genus Gastrolobium which are superficially similar to one other.

Two of these species are prostrate in habit; the other two are more upright but are generally short in stature.

Control Of Cape Tulip, Geoffrey A. Pearce

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

CAPE TULIP is the worst weed in the Avon Valley and northern areas of the Great Southern districts.

It occurs elsewhere to a limited extent but even then it is regarded as a serious weed.

Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely

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

DURING the past decade the acreage of Japanese plums in Western Australia has increased by 10 percent, and production has risen by nearly 40 per cent.

Furthermore, almost 30 per cent, of our trees were still classified as non bearing in 1966, so rapid increases in production are certain to be recorded within the next few years.

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.
