1973 Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on results - Of the four time of planting trials two definitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield …

Potassium For Pastures, Walter Jacob Cox

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

IVIany pastures in the south-west of Western Australia are deficient in potassium or need regular dressings for maximum growth. This article indicates areas and situations in which potassium might be needed, shows how deficiency is diagnosed and gives recommended rates of application.

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden

Experimental Summaries - Plant Research

A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or "optimum" rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the …

1973 Rates Of Phosphate On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on Results - New Land sites (Graphs 1, 2) - The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with higher seeding rates. Low Super Bank (800 kg/ha) (GRAPH 3) - The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain (73M015) the two lupin cultivers and the wheat gave different responses. High Super Bank (>1 OOOkg/ha) …

Plant Adaptation To Cold I. Chlorophyll Ii. Minerals, Peter Rosen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A number of montane herbs in northern Utah typically form flower buds beneath the snow cover and flower either through it or immediately after its recession. Two of these species, one naturally occurring, Claytonia lanceolata, and one cultivated bulb, Galanthus nivalis, were investigated for their response to this stress environment.

Snow depth patterns, chlorophyll content of tissues, and plants grown in light-tight boxes, suggest that light passing through the snow to reach plants growing underneath is not critically involved in the timing of their developmental cycles or in their ability to endure this low temperature environment.

Ability to endure stress …

Inorganic Mercury Uptake And Mercury Tolerance Demonstrated By Several Species Of Algae, Daniel S. Filip

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The inhibition by low concentrations of inorganic mercury has been established for several species of freshwater algae, and a method has been developed to determine mercury levels in algal cells, having good precision at levels as low as one hundred parts per billion.

Rapid sorption of inorganic mercury by glassware was minimized by using heavy algal cultures and short term incubations. The rates and extent of mercury uptake by three species of freshwater green algae were delineated under laboratory conditions. Replicate mercury containing cultures yielded slightly different mercury concentrations upon analysis due to analytical errors and glass sorption. Therefore, percent …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

Reproductive Wastage In Sheep On Clover Areas, Department Of Agriculture, Western Australia

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

Western Australia's 67 per cent lambing for 1970 compares poorly with that of other Australian States, and other countries. From the 12.3 million ewes mated in this State's agricultural areas in 1970, only 8.2 million lambs were marked.

This low 77.7 per cent conception rate sparked the present series of reproductive wastage investigations by the Department's Sheep and Wool Branch.

This report describes the first year's results of the project in W.A.'s "clover disease" areas.

While most trial results have to be examined in the knowledge of low rainfall confounded with high weed competition, some useful and practical conclusions can be drawn.

Soil And Plant Analysis For Mineral Deficiencies, M D. Carroll

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

Soil and plant analysis (testing) has its supporters and its critics. Some of the differences are resolved if the distinction is made between the concept and the practice. Most people would agree with the concept of soil and plant analysis but the practice, or service offered, in any agricultural situation can be subject to valid criticism.

This article defines some of the principles involved and illustrates some of the problems, to provide a better understanding of the usefulness and the limitations of soil and plant analysis as a diagnostic aid in plant and animal nutrition.

Size-Structure Correlation In Developing Roots Of Cissus And Syngonium, David L. Berquam

Journal of the Minnesota Academy of Science

The development of conducting tissues in relation to root size is examined in Cissus sicyoides L. and Syngonium podophyllum Engl. Evidence is presented that such relationships arise earlier in development than has hitherto been described. Their early appearance calls into question the hypothesis that such relationships reflect a solution to problems of water economy in mature tissues. While pattern determination in Syngonium is similar to that anticipated on the basis of published investigations, a new 'kind of size-structure correlation is identified in Cissus. In light of this fact, a need to broaden the philosophical bases for an interpretation of form …

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 …

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.
