Part 5 Comparison Of Genetic Components In Lupin Species, G H. Walton

Experimental Summaries - Plant Research

Influence of genetic components on harvest index. (note the conclusions from these results are especially subject to Statistical Analysis) 1. At three sites out of the four, the acquisition of 'early' gene(s) improved the harvest index. Mount Barker was the exception to this. This was true for both the cosentini, albus and angustifolius varieties. In 1971,when the spring was wetter than 1972,the plant maturity was much less of an influenceupon the harvest index. 2. The alkaloid content of the plant in L. angustifolius doesn°t seem to have a consistent influence upon the harvest index. This was the same experience irn …

Diseases Of Rape, A Bokor

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

A few serious outbreaks of disease occurred in rape crops in Western Australia in 1971 but future crop losses will be much greater where routine disease prevention is not practised.

Control measures for all these diseases are based on efficient destruction of crop residues by grazing and burning and by rotations which allow time for decay of below ground residues.

Effect On Bees Of Insecticides Used On Rape, A C. Kessell

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

Rapeseed could provide beekeepers in Western Australia with a valuable new honey crop—hut insecticidal spraying of rape at flowering time is a potentially serious threat to most commercial beekeepers.

There are indications that insect pollination may improve rapeseed yields, so both growers and beekeepers could gain from a co-operative approach to the problem. Spraying after sundown and preventing spray drift to nearby apiaries should avoid most losses.

Insignia Lowers Wheat Quality, J A. Parish, H. M. Fisher

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

Farmers in Western Australia have been advised not to plant Insignia wheat because it has poor grain quality. Many farmers want to know why Insignia is considered poor quality and what harm it could do. This article answers these questions and suggests alternative, better quality wheats for all present situations.

Recognizability And Reproducibility Of Airphoto Interpreted Landscape Units, Robert Dean Heil

Electronic Theses and Dissertations

A physiographic terrain analysis study using the principles of airphoto interpretation was made: (1) to determine the internal homogeneity of airphoto interpreted mapping units, (2) to determine the variability in characteristics among different occurrences of the same mapping unit, and (3) to determine if the units differentiated were sufficiently different to warrant discrimination. The study was conducted in Sedgewick County, Colorado. The study area was comprised of four distinctly different land forms [sic]: a major river and its associated floodplain and terraces; a level to nearly level loamy upland plain; a level to sloping sandy upland plain; and steeply sloping, …

Evidence For The Presence Of Two Nucleases In Barley Tissue And The Influence Of Genotype On Their Properties, Clay G. Johnson

Electronic Theses and Dissertations

Several lines of evidence have shown that genetic variability exists within the barley species (Hordeum vulgare L.) with respect to the kinetics and specificity of yeast ribonucleic acid degradation. Initial efforts demonstrated that ribonuclease (RNase), in the crude soluble protein fraction from the cultivar Dicktoo, was inhibited by KC1 and phosphate. RNase activity was enhanced if heated to 60 C for short periods. In contrast, RNase in the crude soluble protein of the cultivar Tennessee Winter showed no altered response by either KC1 or phosphate. Maximal RNase activity was at pH 5.0 for extracts of both cultivars (0.16 M KC1), …

Estimation Of N Availability And No3-N Movement In Soils, Raymond Charles Ward

Electronic Theses and Dissertations

Objectives of this study were: (a) to evaluate several N soil tests that are used to estimate soil N availability, and (b) to measure the distribution of inorganic N in the soil profile after an application of fertilizer N. Small grain yield response from an application of 17, 34, or 67 kg N/ha was used as the parameter of N availability. These parameters were related to 23 independent variables by use of a step wise multiple regression program. Nitrogen soil tests and climatic factors (rainfall and temperature) were the independent variables involved in the analysis. Nitrogen soil tests included were …

Some Observations And Comments On Birdsfoot Trefoil, Roy E. Sigafus, W. C. Templeton Jr., T. H. Taylor, J. W. Wyles

Agronomy Notes

Farmer's Bulletin No. 2191, TREFOIL PRODUCTION FOR PASTURE AND HAY, was released by the U.S. Department of Agriculture in July, 1967. This publication noted that acreages of trefoil in the U.S. increased from 770,000 in 1957 to over 2 million acres in 1967. This bulletin is an excellent guide to kinds of trefoils, to the different varieties available, and to general production practices in obtaining stands and in managing this legume. It is stated in the bulletin that birdsfoot trefoil is not recommended south of a line drawn from the Nebraska-Kansas border to the east coast, except at higher elevations. …

Physiological Regulation Of Cyclic Flowering In Flax, Aurora Salazar Hovland

Electronic Theses and Dissertations

The flowering pattern of flax (Linum usitatissimum, L.) is cyclic in nature with periods of blossoming separated by periods of rest. To study the regulation of flowering cycles, four experiments were conducted. The first two dealt with nutritional aspects of cyclic flowering by imposing environmental stresses which conceivably might regulate flowering pattern nutritionally. The third and fourth experiments dealt with regulation from hormonal systems and included in vitro regulation of bud growth by growth regulators as well as characterization of endogenous hormonal systems by fluorimetry and bioassays. In the first experiment, the effects of light intensity, temperature, nitrogen and defoliation …

Bulletins - 3000 - 3999

The systematic investigations of the potential of the Ord area for irrigated farming began during the Second World War when the possibilities of damming the river were first examined, initial soil survey was carried out, and agricultural experiments started. The Kimberley Research Station was established on its present site in 1945. A year later the State and Commonwealth Governments agreed to finance and operate the Station jointly, with CSIRO and the Western Australian Department of Agriculture being responsible for research.

The construction of the main dam designed to store 5,675 million m" ( 4.6 million acre feet) was completed in …

Kimberley Research Station Review Of Progress, 1968-71, Department Of Agriculture, Western Australia

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

The potential for harnessing northern rivers flowing to the Gulf of Carpentaria and the Timor Sea was realised many years ago.

These rivers together are estimated to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes, which comprise the closely settled agricultural areas of South Eastern Australia.

The Kimberley Research Station was established in 1946 to investigate the potential for irrigated agriculture in the Ord River valley. This is a review of the Station's sixth progress report which is being published as Department of Agriculture Bulletin No. 3861.

Glume Blotch Of Wheat, Department Of Agriculture, Western Australia

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

Glume blotch on wheat crops is seen frequently in some areas of Western Australia and was particularly severe in the West Midlands in 1971.

The disease is caused by the fungus Septoria nodorum which infects the leaves, stems and heads of the wheat plant.

Symptoms Of Nutrient Deficiencies In Rape, M G. Mason, J. W. Gertrell

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

Rape is a relatively new crop in Western Australia and this investigation was undertaken to produce visual symptoms of nutrient deficiencies so that they could be recorded and used for diagnosing deficiencies in the field. The appearance of mineral deficiency symptoms can vary considerably with growing conditions, so that symptoms produced in a glasshouse are only a guide to the probable symptoms in the field.

Frost Injury To Cereals In W.A, M W. Perry, A. G. P. Brown

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

Late spring frosts commonly reduce yields and affect the quality of grain in wheat crops, especially in the southern, eastern and north-eastern districts. The damage is usually localised on individual farms, but is sometimes widespread.

Barley, and oats to a lesser extent, are also affected. Average losses of wheat in Western Australia have been estimated at 3 to 5 per cent, per year, or about 2 million bushels on current production figures.

Uptake And Distribution Of Mineral Elements By Burley 21 Tobacco As Influenced By Nitrogen Nutrition And Suckering Practice, J. L. Sims, W. O. Atkinson

Agronomy Notes

Knowledge of nutrient content of tobacco and of removal of nutrients from soil is essential to developing sound fertilization practices for tobacco. Quantities of nutrient elements taken·up by tobacco vary widely. This is because of variations in variety, soil fertility level, fertilizer application, soil moisture, plant population, and other environmental and cultural factors . We conducted the present study to determine the effects of applied N and suckering practice on the content of mineral elements in certain plant parts of burley tobacco.
