A New Look At Sweet Lupins In Western Australia, C M. Francis, M. L. Poole, M. H. Chopping

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

BECAUSE they have a seed protein content of 30 to 45 per cent., sweet lupins are playing a growing role in animal feeding, particularly in the poultry industry. Their value as a protein supplement should ensure a continued local market as at current prices they are highly competitive with soya beans in cost per unit of protein.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The problem of phylogenic relationships within the iguanine phyletic line and the Madagascar iguanids have been investigated in order to explain the discontinuous distribution exhibited by the members of the family Iguanidae. Owing to inconclusive results from cytology and histological methods, the comparative morphology of the anterior osteology, myology, tongues, and hemipenes were used to determine relationships.

An examination of the above structures of the members of the iguanine phyletic lines and a comparison with the Madagascar iguanids indicates the following: ( 1 ) The Madagascar genera Chalarodon and Oplurus appear to be more closely related to each other than …

Stone Fruit Regulations, W J. Hart

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

Stone fruit grading regulations were introduced for the first time recently to keep small, green or badly blemished fruit off the market. This type of fruit is always in poor demand and can spoil the prices obtained for better lines of fruit by creating the impression of heavy supplies.

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.

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …

Planting A Tree Or Shrub?, C Hart

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

THE few minutes spent in planting a tree or shrub properly can be the most important moments of its life.

A little time can mean the difference between a vigorous and a weak root system, and a tree is only as good as its roots. Protection of the roots before planting is also important. Bare-rooted trees need more attention than those in a hessian-wrapped root ball or those growing in a container.

Herbicide Residue And Weed Control In Switchgrass, Charles Nicholas Smith Jr.

Electronic Theses and Dissertations

Purposes of this study were to find an effective herbicide for control of grassy weeds in a pasture, to adapt known laboratory procedures for analyzing residues and to determine amounts of residues during the growing season in treated plots. Nine herbicides were screened for controlling grassy weeds, primarily downy brome (Bromus tectorum L.) in a native pasture. Data indicated 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) applied postemergence at 1 lb/A was the most effective at 85% control. The following year, atrazine, 2-chloro-4, 6-bis­ (ethylamino)-s-triazine (simazine) and 2, 2-dichloropropionic acid (dalapon) each at 1, 2 and 3 lb/A were applied preemergence to switchgrass pasture. Of …

The Biological Activity Of Phytotoxic Extracts From Corynebacterium Sepedonicum, Doran W. Pearson

Open Access Master's Theses (through 2010)

Isolation of a phytotoxin from the ring rot pathogen of potatoes, Corynebacterium sepedonicum, had previously been reported by Strobel (21). The first phase in our study was to investigate more extensively the general nature of this compound. The phytotoxin could possibly be a specific compound associated only with the ring rot pathogen. However, the possibility that the substance could be obtained from sources other than the bacterium had not been completely eliminated. In an attempt to answer this question, three extracts were purified and compared. First, compounds were isolated from a broth culture of bacteria in the manner described …

A Cheaper Herbicide For Wild Oats, Geoffrey A. Pearce

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

A NEW herbicide, *NEOBAN, will reduce the cost of chemical for the control of wild oats in wheat and barley to $2.50 per acre.

Because of the cost of herbicides for wild oats during the past two years, the acreage treated has been declining steadily.

Farmers who thought that spending about $4 per acre was worth while will be delighted with Neoban.
