Bulletin No 3993 - The Control Of Saffron Thistle, G. A. Pearce

Bulletins - 3000 - 3999

Saffron thistle is a primary noxious weed and is widespread throughout the drier parts of Western Australia. When growing in pasture its prickly growth habit discourages animals from grazing amongst it so that its presence results in the loss of feed. In crops it reduces yield and results in dockage when seed is found in harvested grain.

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.

The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …

Analysis Of The Presettlement Forests Of The Unglaciated Portions Of Southern Illinois, Lawrence A. Leitner

All-Inclusive List of Electronic Theses and Dissertations

This research used the data on witness trees found in the surveyors' records of the General Land Office surveys of 1805-1815 as the basis for studying the primeval forests of unglaciated southern Illinois. Via computer, the random pairs and closest individual methods of plotless sampling were used to develop stand attributes tables, with soil association boundaries defining the limits of forest stands. A vegetation map was developed from these stands. Four major forest types were delineated: Upland Oak, nixed Hardwoods, Swamp Forest, and Floodplain Forest. The Upland Oak Forest, with lowest density (175.9/ha or 71.2/acre) and basal area (21.3 rn …

Fisheries Report No 23 - The Management Of Nature Reserves In Western Australia, Andrew A. Burbidge, Trevor Evans

Fisheries Research Reports

The number and area of Nature Reserves in Western Australia has grown rapidly in recent times. At 80 June 1975 there were 491 reserves with an area of 5 103 037 hectares. By 31 December 1975, with the inclusion of reserves for the Conservation of Flora in the definition of a Nature Reserve, there were 900 reserves totalling 5 317 965 ha. With the implementation of the Environmental Protection Authority's recommendations based on the Conservation Through Reserves Committee's Report on Systems 4, 8, 9, 10, 11 and 12 the Nature Reserve System will jump to 985 reserves with an area …

Seasonal Changes In Sexual Activity And Serum Levels Of Lh And Testosterone In Finnish Landrace And Suffolk Rams, B. D. Schanbacher, D. D. Lunstra

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A procedure for assessing sexual activity (libido) in individual rams is described. Mating activity measured by this procedure and serum levels of luteinizing hormone (LH) and testosterone in Finnish Landrace and Suffolk rams was determined at 8-week intervals from October, 1974 through October, 1975. Seasonal changes were observed for serum LH, testosterone and libido index scores. Mating activity in rams was highest for both breeds during the peak breeding season (October) and declined 50% by late spring and summer before it increased the next October.

Serum LH concentrations were lowest in May (.54 ng/ml) and increased abruptly in July ( …

Comparison Of Economic Returns From Grain Crops, H M. Fisher

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

While wheat is still generally the most profitable crop in Western Australia the relative profitability of barley and linseed has risen in the last few years; in southern areas they are likely to be at least as profitable as wheat.

Oats has fallen in profitability relative to wheat, and grain legumes have suffered a marked fall. Yields of these grains have increased with the introduction of new varieties but their price increases have not kept pace with those of wheat and barley. The present relationship of yields and costs indicates that substantial price changes will be needed to change the …

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …

The item considered most often when estimating the cost of a grain storage facility is capacity. Of equal or greater importance is daily harvest rate. Other important considerations include drying method, materials handling equipment, energy cost, facility arrangement, labor requirements, grain quality and management ability. Only through a comparison of facilities which offer similar capacity, capability and convenience can the purchaser obtain his best system.

Soil Salinity Measurement By The Four-Electrode Probe Technique, K. Sriotai, John T. Gilmour

Journal of the Arkansas Academy of Science

The four-electrode probe method was tested on a Crowley silt loam soil in which salt type, salt content, and water content were varied. Theory associated with this technique of assessing soil salinity was verified. Equations were developed which quantified the relationships between soil electrical conductivity obtained by the four-electrode probe technique (EC), saturation extract (EC1), and 1:2 soil to water extract (EC2).
