Control Of Wild Oats, J G. Paterson

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

WILD OATS are widespread throughout the world.

Their importance can be gauged from the fact that in the wheat growing areas of Canada and the U.S.A. some 60 million acres are infested.

Two chemicals are now available for the control of wild oats in wheat. This article compares their relative merits and gives recommendations for their use.

Control Of Weeds In Garden Areas, Geoffrey A. Pearce

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

THE present-day gardener does not appear to relish the tedious job of removing weeds by hand. It is a never-ending task and no sooner is one germination controlled than another appears.

Modern herbicides provide a ready answer for overcoming the weed problem in the home garden, but it is essential to select the correct chemical and to understand its limitations.

A Measure Of Clover Infertility In Ewes, N Davenport

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

SERIOUS impairment of the breeding ability of ewes grazed for prolonged periods on growing pastures containing dominant subterranean clover has been experienced in Western Australia for many years.

The first widespread recognition of the problem coincided with the upsurge of improved pasture establishment based on the Dwalganup variety of subterranean clover in the higher rainfall sections of the wheatbelt and adjacent sheep raising areas to the west and south.

Phalaris Staggers : Prevention By Cobalt Bullets, Bryan J. Gorddard, P. P. Mann, A. J. Hadlow

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

FARMERS in the south west of Western Australia are familiar with the use of cobalt for the prevention of ill-thrift and deaths due to cobalt deficiency in sheep and cattle.

Less common is the use of cobalt for the prevention of chronic phalaris poisoning, known as phalaris staggers.

This condition is well known in eastern Australia, but only isolated cases have been recorded in W.A. no doubt due to the relatively small area sown to phalaris in this state.

Department Of Agriculture Services : The Botany Branch And The W.A. Herbarium, Department Of Agriculture, Western Australia

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

ALTHOUGH the flora of Western Australia strongly attracted early botanists and collectors, it was virtually neglected by settlers faced with a century or more of hard pioneering.

Only recently has enthusiasm for our remarkable flora developed within the State and, with the formation of sponsoring societies and the establishment of the Kings Park Botanic Gardens, native species have become popular in home and civic gardens.

Which Cereal Gives The Best Return?, H M. Fisher

Poison Plants Of Western Australia : The Toxic Species Of The Genera Gastrolobium And Oxylobium. 1. Characteristics Of The Group, T E H Aplin

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

THE toxic species of the genera Gastrolobium and Oxylobium are a unique group of poison plants which have caused considerable economic loss to stock-raisers in Western Australia ever since the early days of settlement.

These plants are widely distributed over the agricultural areas of the south-west, and, with the opening up of large tracts of land for stock-raising, the danger is as high as it has even been.

The Art Of Making Jams And Jellies, O. Evans Scott

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

JAM-MAKING is a traditional art of Australian country homes and has its reward in economy and a supply of food with extra appeal.

It can also provide items otherwise unobtainable, such as quondong jelly or rosella jam if you are lucky enough to have access to any of these delicious jam-making fruit.
