The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 4
THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.
In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.
The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.
The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald
The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald
Journal of the Department of Agriculture, Western Australia, Series 4
OF the 17,800 square miles of Ord River catchment area, an estimated 1,450 square miles of country is subject to varying degrees of erosion.
This lies astride the Ord River and its major tributaries, the Elvire, Negri, Stirling, Panton, Turner, Nicholson and RB rivers.
The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.
Phalaris Staggers : Prevention By Cobalt Bullets, Bryan J. Gorddard, P. P. Mann, A. J. Hadlow
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.

Land Grading In South West Irrigation Areas, 1966-67, Department Of Agriculture, Western Australia
Land Grading In South West Irrigation Areas, 1966-67, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Land grading in the South West Irrigation Areas with modern earth moving equipment first commenced in 1949.
The advantages of land grading are well recognised by farmers and this season grading operations were carried out on 208 farms.
Recommendations For The Establishment Of Harbinger Medic In The Northern Wheatbelt, R J. Parkin
Recommendations For The Establishment Of Harbinger Medic In The Northern Wheatbelt, R J. Parkin
Journal of the Department of Agriculture, Western Australia, Series 4
Harbinger is an early-maturing medic that has met with success on some soil types, especially in the northern wheatbelt.
Similar to Cyprus barrel medic but best suited to different soil types, harbinger adds to the range of pasture legumes available for sowing in under 16 in. annual rainfall areas.
Pumping And Horsepower, R P. Harington
Pumping And Horsepower, R P. Harington
Journal of the Department of Agriculture, Western Australia, Series 4
WATER is vital to the survival of plants and animals and its availability will influence the site of the homestead and the farm layout generally.
This article describes some of the factors involved in the installation of a pumping outfit for domestic and stock requirements.

The Australian Field Cricket, J A. Button
Journal of the Department of Agriculture, Western Australia, Series 4
THE Australian field cricket, or the black field cricket as it is sometimes known, is a native of Australia and is widely distributed throughout the south western, south and south eastern sections of the continent.
The Hamel Nursery, K S. Cole
The Hamel Nursery, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
A LITTLE known, but highly productive use of irrigation water occurs at the Forestry Department Nursery, Hamel.
Seedlings of trees and shrubs are raised during the summer for sale the following winter.
Sales are made to the farming community and many trees are used by the Forest Department in its reafforestation programmes.

Water Blooms, T E H Aplin
Water Blooms, T E H Aplin
Journal of the Department of Agriculture, Western Australia, Series 4
WHEN a body of water becomes discoloured with a super-abundance of free-floating, microscopic plant or, in rare cases, animal life, it is said to develop a "water bloom."
This article discusses some aspects of the appearance of water blooms, particularly those caused by algae, and with the effects that certain toxic algae have on livestock.
