1975 South West Sub.Clover Root Rot - 1975 Cultivation Experiments, M J. Barbetti, G C. Macnish

Experimental Summaries - Plant Research

Trials were established in 1975 in the South West of WA to investigate the effect of time of cultivation, and nitrogen application, upon the incidence and severity of both tap and lateral root rot subterranean clover. Nitrogen application had little in the way of consistent effects. Cultivation reduced the levels of both tap and lateral root rot in many instances. These effects were most obvious and consistent at about the end of May. Cultivation just prior to or just after the break of season were the best cultivation treatments. Cultivation does appear to show some promise as a means of …

1975 Drought Responses Of Wheat Cultivars - Environment Responses Of Subterranean Clover., R N. Weir

Experimental Summaries - Plant Research

Environment responses of subterranean clover. Aim - To clarify the responses of four cultivars to temperature, vernalisation and photoperiod. Method - Dinninup, Midland B, Geraldton and Blackwood sub clover was grown in phytotron cabinets under 14 hour and 10 hour photoperiods and temperatures 10°c day/5°c night, l5/l0°c, 20/l5°C, 25/20°c. A seed vernalisation treatment of 6 weeks refrigeration of swelled seed was included. Dissections were made to observe first floral initiation and first flower production was noted. Conclusions - Higher temperatures either had no effect or delayed floral initiation, but accelerated flower development greatly from initiation to anthesis. Photoperiod and vernalisation …

Bulletin 3933 - Trickle Irrigation For Home Gardens, K Cole

Bulletins - 3000 - 3999

The use of trickle irrigation in the home garden can save money, time and water.

Trickle irrigation is a concept first used in glasshouses in England, then applied to field crops in Israel and developed and refined in Australia and America. Today it is widely used in orchards, vineyards, vegetable gardens and now has gained wide acceptance in the growing of ornamental plants.

Any good trickle system uses small quantities of water over an extended period of time. In the home garden, flows of 2.25 litres to 4.5 litres per hour are usual though for small shrubs lesser amounts may …

Fisheries Report No 14 - Wilson Inlet - A Seasonally Closed Western Australian South Coast Estuary, R C.J. Lenanton

Fisheries Research Reports

Considerable conflict has existed for many years between professional fishing, recreational usage and development in the west and south coast estuaries of Western Australia. One of the areas where intense conflict exists is Wilson Inlet.

The Government's task of advising the various interests concerned in these conflicts has been difficult, due to the lack of knowledge of estuarine fauna and environment in relation to usage and development.

The objective of this report is to present a preliminary description of the Wilson Inlet environment, to record the history of netting closures in the Inlet, and to discuss the history of the …

Bulletin No 3883 - Dairying In W.A., Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.

Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per· hectare.

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …

Pasture Species Investigations - Wheat Belt (May, 1975), N. R. Mckeown

Experimental Summaries - Plant Research

Results from trials comparing the growth and persistence of a number of annual pasture legumes are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall > 400 mm Zone B - Average annual rainfall 345 - 400 mm Zone C - Average annual rainfall < 345 mm and then, further, on soil type. District Rainfall, 1974. 71LG16,, 72LG3, 74KA3, 70OTS2, 72TS5, 70NA3, 71TS22, 74NO3, 70ME4. The early break, with good rainfall continuing through most of the growing season, provided optimal conditions for most wheat belt trials. These conditions were in direct contrast to the dry years of the late 1960's and early 1970's. In 1974, legume growth on droughty deep sands should have been at its best. Serradella responded at Kukerin in direct relationship with earlier heavy dressings of potash. West of Three Springs, serradella and Tornafield medic stayed a little ahead of Harbinger medic and well ahead of Daliak sub. clover and rose clover. On deep sands at Marchagee and Arrino, subterranean clover was the only species worth considering. The failure of Eragrostis curvula to persist through the dry 1973-74 summer after good germination in late winter, indicates a need for more work on the establishment of this grass on deep sands. The low yields of dry matter at Tincurrin do not offer much incentive for such work, but Eragrostis, lupins and serradella probably give the best chance of pasturing the grossly infertile, erodable sands. Under favourable conditions, Geraldton sub. clover continued to show its versatility and aggressiveness. On an alkaline loamy sand at Lake King, waterlogged for periods during the winter, Dwalganup, Geraldton and Northam A produced more dry matter than a wide range of other pasture legumes. At Walgoolan, Geraldton maintained better than 503 content in mixtures with other sub. clover cultivars sown in 1970, while in a trial at Marchagee there was evidence of gradual, aggressive regeneration of Geraldton from a sparse pasture sown before the trial. Only two new legume species trials were planted in 1974, and these were not successful. Trial 74KA3, east of Katanning, demonstrated the need for timely planting. Had seed been available on time, the trial would have been planted before the onset of heavy rains and would have given better results. The failure of Tornafield and Harbinger on 74N03 should not weight the record unduly against these medics; :they have never excelled on clay loams, and they were sorely harassed by redlegged earthmite. The medics will not be replanted, but Northam A and Geraldton will be observed in 1975. :

Pasture Deterioration - High Rainfall Areas, D J. Gillespie

Weed Trials 1974 Summary - Annual Ryegrass Control - Wild Oats - Cereal Tolerance To 2,4-D - Annual Ryegrass Toxicity, G. A. Pearce

Experimental Summaries - Plant Research

A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying …

Grain Moisture And The Weather : What Can The Records Tell Us?, M W. Perry, P. A. Fievez

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

The expansion of cereal production in areas along the south coast has exposed harvesting problems associated with high grain moisture.

A grain delivery standard of 12 per cent moisture means that, in the absence of grain drying facilities, harvesting times in the field are restricted to those hours when grain moisture falls below this figure.

Grain moisture, however, remains the major problem and for planning purposes, producers require an estimate of the harvesting time available in a given year. This will depend on all the climatic variables which affect grain moisture. These include rainfall and dew which deposit water directly …

Nitrogen Fertilisers For Pasture Production, Walter Jacob Cox, K Hawley

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

At current prices nitrogen fertiliser is not an economic substitute for good clover pastures, but it can supplement the system by increasing nitrogen supply at peak growth periods. It can also provide useful increases in pasture production at critical feed times. Nitrogen usage for pasture production is still in the experimental stages and small areas should be tried before large-scale application.

A Submission For The Award Of An Associate Diploma In Health Education, Claremont Teachers College

Research outputs pre 2011

Health education is a process which effects changes in the health practices of people and in the knowledge and attitudes related to such changes. Education is an internal process for the individual concerned. He educates himself, even though his education is assisted by such means as contacts with health workers, appeals directed to him, information made available, clarification of issues, alternatives, and consequences as a basis for a rational choice. Education thus places responsibility on the individual and is essentially different from a compliance approach. It involves motivation, communication and decision-making. Planned education must take into account the relevant knowledge …

The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis

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

Lucerne, the world's most important fodder legume, has never won largescale acceptance in West Australian farming, largely because of our success with productive subterranean clover pastures. But recent disease problems on sub. clover stands have led to greater interest in alternative species, especially lucerne, for higher rainfall areas.

This article summarises our knowledge of lucerne establishment and management in W.A. and reviews current research aimed at achieving better results from lucerne.

Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones

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

In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture.
