Bulletin 4152 - Sheep In Western Australia, R J. Suiter

Bulletins 4000 -

Western Australia's sheep industry started in the early 1830s when the first flock-owners grazed their sheep on extensive areas of native vegetation, often by shepherding on unfenced country. Later, farm flocks built up as settlers cleared and fenced land for cultivation, and 'pastoral' or 'station' sheep were confined to fenced areas of native vegetation, leased from the Government.

By 1900, more than 75 per cent of Western Australia's sheep were still classed as 'pastoral', but by 1987/88, the pastoral areas carried only 2 million of the 34.1 million State flock.

Today, many former sheep stations carry cattle, which survive better …

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

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

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …

The Sandplain Lupin : Its Nutritional Value And Grazing Management, P W. Morcombe

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

The sandplain lupin or Western Australian blue lupin (Lupinus cosentinii) was introduced to the West Midlands at the turn of the last century. Since that time it has been used as a self-regenerating summer forage for sheep and cattle.

Being deep rooted, it has adapted well to the sandy soils from Perth to Northampton, and plantings now cover more than 100,000 ha.

As few other improved pasture species will persist on these deep sands the sandplain lupin provides an important source of summer feed for grazing livestock. A stand can be grazed throughout summer at stocking rates of 10 to …

One of the many benefitsof growing narrow-leaved lupins in a crop rotation (Rowland et al 1988) in the increased yield of the following cereal crop as a result of the improved nitrogen level of the soil.

This article reports the results from 41 wheat/lupin rotation trials involving a range of nitrogen rates throughout the Western Australian agricultural area between 1978 and 1987. These trials allowed scientists to assess the interaction of nitrogen fertilization with previous cropping history and to estimate some of the contribution of the nitrogen and other effects of lupins within the crop rotations. The results provide some …

Frost Injury To Wheat, S P. Loss

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

Frost injury has not been a major concern to the Western Australian wheat industry despite causing spectacular but irregular crop losses on some farms.

The development of suitable herbicides, direct drilling technology and the adoption of early flowering varieties in the late 1970s and early 1980s led to wheat crops being sown and flowering earlier than previously. This resulted in an increase in the incidence of frost damage.

Research into frost indicates that most wheat producers face low to moderate risks of yield loss caused by frost. However, individual farms in particular years can suffer devestating widespread losses. Grost injury …

Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone

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

For the past few years, the Department of Agriculture has been fattening cattle on the forage shrub leucaena which is grown under irrigation with pangola grass. About 400ha of leucaena is under commercial production in the Kimberley.

Cattle grazing leucaena show promising growth rates but other problems need to be overcome before its use is more widely adopted. Leucaena establishes slowly. It is also costly to transport fattened cattle to southern abbatoirs.

Tissue Culture In Rice (Oryza Sativa L. Subsp. Japonica Var. Lemont), Young M. Woo

Masters Theses

The purpose of this study was to obtain callus induction and subsequent plantlet regeneration from various explants of rice (Oryza sativa L. subsp. japonica var. Lemont). Callus induction occurred from the somatic cells of ovary wall, immature and mature embryos, immature endosperm, stem nodes, and seedlings. Plantlets were regenerated from embryo-, endosperm-, and stem node-derived calli on differentiation media. Stem nodes were the most responsive to callus induction. Requirements for optimal callus formation and plantlet regeneration differed from each culture. The study investigated the effects of cold treatment of explants, initial culture in darkness, media, and subculture for individual explant …

Characterization Of Rice (Oryza Sativa L.) Roots Versus Root Pulling Resistance As Selection Indices For Draught Tolerance, Mazo Price, R. H. Dilday, Arthur L. Allen

Journal of the Arkansas Academy of Science

A technique described as Root Pulling Resistance (RPR) was used to evaluate genotypic differences in root growth and development of 50 rice germplasm accessions and cultivars. Several root characteristics in rice are associated with drought tolerance and avoidance capability of plants. The RPR measurements showed a significant positive correlation with maximum root length (r=0.69), root thickness (r=0.75), branching number (r=0.75), and root dry weight (r= 0.82). Rice genotypes that had a high RPR value were identified as having longer, thicker, and denser root systems. The data indicated that high RPR measurements are strongly correlated with greater root penetration. Munji Sufaid …

Male Sterility In Soybean-An Overview, Robert Graybosch, Reid G. Palmer

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

The most common type of reproductive mutations observed in the soybean [Glycine max (L.) Merr.]are those that induce male sterility.The high frequency of occurrence of male-sterile mutations indicates that a number of genes influence the processes of microgametogenesis and microsporogenesis. The current knowledge of these mutations is summarized. The origins of male-sterile mutations, their inheritance patterns, and known linkage relationships are detailed. The phenotypic expression of male-sterile mutations, including their effects on both male and female reproduction, is discussed. The influence of environment on the expressivity of male sterile mutations, and the effects of male-sterile mutations on physiological processes …
