Pasture Legume Varieties And Ewe Fertility, T Marshall, H. E. Fels, H. G. Neil, R. C. Rossiter

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

ALTHOUGH it was first thought that all varieties of subterranean clover would cause ewe infertility, research in the last 10 to 15 years has shown that varieties differ in potency.

The relative level of potency has also been shown to remain consistent for any one variety under normal conditions.

Fertility Build Up Under Northern Wheatbelt Pastures, M L. Poole

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

Experiments on two farmers' properties demonstrated that legume pastures increase the fertility of northern wheatbelt soils.

Crops on legume pastures had higher yields than crops on volunteer pasture.

The experiments also indicated the most productive legume species for each situation and demonstrated that nitrogen added by legumes has a residual effect in the soil.

Pasture Improvement In South Western Australia, J W. Malcolm

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

"There is no doubt that Australia's enhanced prosperity in the last 30 years has been dependent in no small measure on the use of legume-based pastures." E. M. Hutron, June, 1968. *

THE LAST 30 years have seen an increased interest in pasture improvement which has transformed much of Western Australia. Large areas have been sown to new and improved pasture species—as a result productivity of both livestock and cereal enterprises has risen.

Legume Inoculants For 1967, W A. Shipton

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

PERIODIC changes are made in the strains of rhizobia released for the inoculation of various legume groups.

These changes are made when it is evident from experimental data that better strains of rhizobia are available, or that the old ones are no longer effective.

New strains of rhizobia may give improved nodulation of legume seedlings or increase dry matter yields.

Pasture Seed Production, 1966 : Statistics And Comments, B J. Quinlivan

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

THE marketing of pasture seeds differs from that of some other primary products in that there are no guaranteed prices.

A knowledge of potential supply and demand for the various species and strains is just as important to the seed producer as good production techniques.
