Surplus Cereal Crops For Sheep Feed, H E. Fels

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

SINCE the introduction of wheat quotas many farmers have considered feeding unsaleable grain to sheep.

The three alternative methods of feeding this grain to sheep are

• as standing crops

• as grain supplements, fed in the paddock

• as grain plus hay, in a feedlot.

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley

Masters Theses & Specialist Projects

The effects of chemical additives on the fermentation pattern and subsequent feeding value of corn silage was investigated over a two year period. Corn plants harvested in August 1967 (Experiment I) were ensiled with no additive, 3.50 per cent area, or urea-mineral mix supplying an equal amount of urea. Those harvested in August 1968 (Experiment II) were ensiled with no additive, 0.50 per cent urea, or 0.75 per cent urea. The nutritive value of these silages was evaluated chemically and by lactation trials.

:he addition of urea alone, or in combination with minerals elevated the initial pH and buffered against …

Crop Rationing : A Useful Drought Feeding Technique, H E. Fels

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

A TRIAL carried out during the 1969 drought demonstrated that rationing standing crop is a practical method of feeding it to sheep when feed is scarce.

Rationing will be mainly a drought feeding technique for that part of the crop which will definitely be used as sheep feed. Crop that may or may not be needed for sheep would normally be harvested and the grain kept as a contingency allowance.

1970 Results Of Field Experiments, T O. Albertson

Experimental Summaries - Plant Research

"1970· Progress Eight of the 5 unreplicated trials were cropped without fertiliser. Seven were harvested (severe weed infestation ruined 66KA 7). Three trials left under pasture responded to the fertiliser treatments and were cut for dry matter production. The remaining four trials left under pasture grew badly, became weed dominant and were not rated for growth differences between treatments or cut for dry matter production. The replicated trials at Avondale and Newdegate were also cropped, without fertiliser. The replicated trials at Wongan Hills Research Station and Chapman did not visually respond to treatments and were not cut. 69WHl5 succumbed to …

Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall

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

A recent field experiment on established pastures at Esperance Downs Research Station has demonstrated a relationship between superphosphate application, pasture oestrogens and oestrogenic response in sheep.

Results of the experiment indicate that on phosphate deficient soils carrying oestrogenic clovers, the levels of oestrogenic materials in the pasture are increased if superphosphate applications are below those recommended for healthy pasture growth.

Annual Summary Of Experimental Results 1970-71 - Evaluation Of Pasture Species, G H. Walton

Experimental Summaries - Plant Research

During 1970 interest in the small ungrazed Legume Species Trials was reduced to ten trials located in the more troublesome areas. Five of the trials are on the sandy soils of the Midland Plain three trials are in Merredin-Southern·cross region, one is on deep sand at Tincurrin and the other is at Pindar. All thesites are sandy soils on which the sub clover strains appear to perform the best. The newer trials are investigating the value of sub clover cultivars such as Northam A,Mt Helena A, Shenton Park A, and Daglish. These trials will be the subject of a special …

Experimental Summaries - Plant Research

Medium Rainfall Zone Trials Eleven replications of the basic rate of P, rate of SO4-S and S experiments were maintained during 1970 in the 20in - 30 in. rainfall zone. Soil types examined were the very gravelly soils (5 reps, 4 sites), sands or loamy sands over gravel or clay (3 sites) and sandplain soils (3 reps, 2 sites). In all cases except one, fertiliser history was not reliable, but in every case well over one ton of super had been applied. over a period of over 15 years.

Systematic Infections For The Assay Of Plant Viruses, Myron K. Brakke

Department of Plant Pathology: Faculty Publications

The first infectivity assays of plant viruses relied on the percentage of inoculated plants becoming systemically infected. The use of systemic infections for assays became unfashionable, however, after the discovery of local lesions and the demonstration that their numbers depended on virus concentration. Continued emphasis on local lesions over the years led to the widely held belief that systemic infections could not be used for a reliable and accurate assay of plant viruses. There was never any good statistical evidence for this viewpoint. In fact, no thorough investigation has been published of the accuracy of "systemic assays" of plant viruses, …

Identification Of Seeds Of Undesirable Weeds, J R. Peirce

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

PREVENTING the introduction of weeds to a farm is a far cheaper proposition compared to the expensive and laborious process of eradicating a well established infestation.

Unfortunately most weeds establish themselves as plants before they are identified, the main reason being farmers are often unable to recognise weeds in the seed stage.

The Protection Of Primary Production : The Role Of The Agriculture Protection Board Of Western Australia, A R. Tomlinson

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

THE main function of the Agriculture Protection Board of W.A. is, as its name implies, "protection", and, in this case, it is the State's primary production which is being protected from pest animals, birds and weeds.

In general, the Board's activities are centred on the prevention, destruction or management of animals and plants which are troublesome to agricultural or pastoral production, or are capable of being troublesome.

The Effect Of Two Growth Retardant Chemicals, Cycocel And B-Nine, On Certain Nitrogeneous Components In Barley Seedlings, Linda Kinser

Masters Theses & Specialist Projects

Certain chemicals are known to inhibit growth in many plant species. These chemicals possess a common trait, the ability to inhibit stem elongation by suppressing the activity of the subapical meristematic region (11). These growth retardants have been extensively studied during the past several years in an effort to determine the biochemical mechanism responsible for reduction in plant height. The characteristic effect of these chemical retardants on the growth pattern has been described as producing plants with shorter, thicker stems and broader, darker green leaves. Tolbert, however, noted that although plants treated with the plant growth retardant, Cycocel, (2-chloroethyltrimethlammoniumchloride) and …

Ultrastructural Investigations Of Tilletia Caries Teliospores, James Vincent Allen

Theses and Dissertations

The purpose of this study was to investigate the ultrastructure of Tilletia caries teliospores. Specimens were prepared for viewing in the electron microscope by freeze-etching and thin-sectioning techniques. Thin-sectioning techniques gave excellent results with the teliospore walls and the lipid bodies within the teliospore but failed to adequately fix the membranes and internal organelle systems. Micrographs of Tilletia caries teliospores prepared using thin-sectioning show three major wall layers and two partition wall layers and abundant lipid bodies. The freeze-etch method of spore preparation proved superior to the thin-sectioning used in this study to reveal the internal organelle systems of the …

The Identification Of A Germination Factor For Basidiospores Of Psilocybe Mutans, Neal K. Van Alfen

Theses and Dissertations

Basidiospores of the Basidiomycete Psilocybe mutans have been found to germinate only in the presence of water extracts of animal dung. The chemical nature of the factor present in the dung that induces germination is not known, nor has it ever been isolated· Experiments showed that extracts of bile salts cause the basidiospores to germinate, indicating that since bile salts are found in dung, they may be the factor which stimulates the spores to germinate. Investigations of the properties of the factor in dung show that the factor has solubility properties that are similar to those of the bile acids. …

Animal Performance On Crested Wheatgrass Pastures During May And June, Fort Rock, Oregon, D. W. Hedrick, W. M. Moser, A. L. Steninger, R. A. Long

Department of Agronomy and Horticulture: Faculty Publications

Average animal performance data of 1.5 lb/animal daily gain, two calendar months of grazing, and 20 lb/acre gain were obtained from 5 years of using crested wheatgrass under a 2-crop (May) and 1-crop (June) system of grazing. Regrowth was obtained on early use (2-crop) pastures in only 2-out of the 5 years. Extension of results to users was hastened by involving ranchers, a county agent, and a federal agency manager in the study.
