The Fruit Industry In Other Lands. 4. The United States Of America (Continued), Frank Melville

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

COMMERCIAL pear growing was seen only in Washington State where production is in the vicinity of five million bushels or about 12 per cent, of the total fruit production of the State.

Two-thirds of the pears are Bartletts which are used extensively for canning. The other main variety is D'Anjou with lesser quantities of Bosc and Winter Nelis all of which are used for the fresh fruit trade.

In the last six years a serious depletion in tree numbers has occurred due to the inroads of Pear Decline a new disease the cause of which at present is unknown.

Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins

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

ONE of the most important factors influencing Western Australian agriculture in the last 20 years has been the development of permanent pastures together with the associated practice of ley farming.

Although the increased use of pasture plants, and particularly subterranean clover, has increased the general fertility of many areas it has also accentuated various problems, including those relating to insect control.

Summer fallow was a strong deterrent to such pests as the red-legged earth mite, the lucerne flea, and webworm and these and several other creatures have shown a tendency to increase under new farming methods.

Weed Research. 7. Weed Control Around The Yard, Geoffrey A. Pearce

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

MANY farmers and city householders have weed problems around houses and sheds which can be readily overcome by treatment with appropriate herbicides.

The risk from fire through weeds and unslightly growth can easily be removed and an area free of any plant growth can be maintained with little effort for a considerable period.

Soursob (Oxalis Pes-Caprae L.), G R W Meadly

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

DURING winter and spring, the yellow colouration of paddocks is not always due to the flowers of the widely distributed Capeweed.

In some districts, particularly in the Avon Valley, the yellow-flowered soursob (Oxalis pes-caprae L.), has become firmly established.

The genus Oxalis contains 800 or more different species, the two main natural centres of distribution being South Africa and tropical and extra-tropical South America.

Afghan Thistle (Solanum Hystrix R. Br.), G R W Meadly

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

DURING the summer months it is usual to receive many specimens of a prickly plant with blue flowers similar to those of a potato. It is commonly known as Afghan Thistle or Prickly Potato Weed.

This plant is not a thistle, although it has the prickly foliage characteristic of many members of that group. The botanical name is Solanum hystrix which places it in the same family as the tomato, potato and tobacco.

Relatives also include weeds such as the thornapples, black nightshade and apple of Sodom.

The name Prickly Potato Weed, although somewhat unwieldy is therefore more appropriate than …

Lupinosis, H W. Bennetts

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

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern.

Some Factors Affecting The Baking Quality In Wheat, A R. Egan

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

ALTHOUGH between 10 per cent, and 15 per cent, of wheat consumed in Australia is used in feed for domestic animals, the primary usage in home consumption is for bread-making.

Exports, which account for roughly 75 per cent, of the normal Australian crop, are also mainly used in bread-making.

Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox

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

THE establishment of the Wiluna office of the North-West Branch marked the commencement of a series of investigations into the pastures of the mulga zone.

Unlike the agricultural areas where a fund of knowledge exists on the growth habits of the pastures, the pastures of this area were completely unknown.

The preliminary investigations had to be aimed at forming an understanding of the reactions of the various plants to rain, to temperature and seasonal conditions and to grazing in an area of extremely low rainfall reliability.

Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox

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

THE mulga pastoral zone is so named since most of its area is dominated by Mulga (Acacia aneura).

The mulga is found associated with shrubs and grasses in almost all plant habitats. In its various forms it can associate with spinifex (Triodia basedowi), Wandarrie Grasses (Danthonia, Eragostis and Eriachne spp.) and with low shrubs on flood plains, hills and breakaways. It may even attempt to become established in salty communities, though this is never completely successful.

The scene the area offers from its low hills is one of a succession of low undulations, occasionally scarred by creeks or breakaways and …

Vegetational Changes In A Shadscale-Winterfat Plant Association During Twenty-Three Years Of Controlled Grazing, Kimball T. Harper

Theses and Dissertations

This paper will report the results of a study commenced in 1935, at the Desert Experimental Range, Pine Valley, Millard County, Utah, to determine the relative effects of various grazing treatments upon the plant members of the shadscale [Atriplex confertifolia (Torr. And Frem.) S. Wats.] - winterfat [Eurotia lanata (Pursh) Moq.] plant association. Results of this study indicate that distinct vegetational changes have occurred within that plant association during twenty-three years of controlled grazing by sheep.

Pharmacological Studies Of Antidiabetic Chinese Herbs, Mun Fa Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Rehmannia glutinosa, Atractylus ovata, and Polygonatum chinense have all been employed by the Chinese as oral antidiabetic agents and reported by Min (1928), Kin (1931), and Li et al. (1936) to possess hypoglycemic activity. This prompted the pharmacological studies of these herbs.

Materials and methods. Their pharmacognosy was condensed from all available Chinese and scientific literature. Preliminary chemical and physical analyses included determinations for moisture, ash, crude fat, carbohydrates, protein, phosphorus, pH, alkaloids, melting point, and spectroscopy. Employing the Somogyi-Nelson method, their glycemic activity was studied in rats, rabbits, and dogs. Stress reactions were minimized. The effect …

Native Grassland Of Southwestern Iowa, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Studies of the prairie by the writer and Fitzpatrick during 1922-33 were both extensive and intensive. They were extensive in that they included an area of 60,000 sq. mi. in western Iowa, eastern Nebraska and portions of the four adjoining states. They were intensive in that a record of the kinds and distribution of grasses, the abundance and relative importance of forbs, and other pertinent data were ascertained and recorded separately for each of 135 selected areas. Since most of these prairies were examined two or more times each growing season, and many repeatedly during a five-year period, a clear, …

Use Of The Antibiotics, Streptomycin And Terramycin, As Growth Stimulants For Orchid Seedlings, Margaret W. O'Neill

Biology ETDs

Antibiotics first came to the public's attention in 1945, when penicillin and streptomycin were released by the United States government to fight human diseases. Later, other antibiotics were released and experimental work was done on control of plant and animal diseases. By 1948 plant pathologists found that certain plant diseases such as walnut blight, tomato and pepper bacterial spot, soft rot, cucumber, downy mildew, chrysanthemum bacterial wilt, and lilac bacterial blight could be controlled by antibiotics.

Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

Characteristics Of Manila And Related Soil Series, Flayeh H. Altaie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In many parts of the world soils have been found that have apparently been formed under climatic conditions that no longer exist. In many places in northern Utah in areas associated with ancient Lake Bonneville, deep soils, fine-textured and non-calcareous, have been observed immediately above the highest shore line of the ancient lake. These soils have essentially no free carbonates to depths ranging from 4 to 15 feet, even though they exist on relatively steep slopes. In Davis and Utah Counties, soils having these characteristics have been given the tentative series name, Manila.

Soils studied for this thesis include one …

Soil Aggregation By Microorganisms Following Soil Fumigation, T. M. Mccalla, Francis A. Haskins, R. D. Curley

Department of Agronomy and Horticulture: Faculty Publications

The influence of autoclaving and of fumigation with eight chemical formulations upon microbial numbers in straw-amended Peorian loess and the extent to which these treatments affect the degree of aggregation brought about by subsequently introduced inocula were determined. A mixed soil flora, Stachybotrys atra and a blank inoculum consisting of sterile salt solution, were compared. Only in the autoclaved soil was a mixed soil flora inoculum consistently superior to the blank inoculum in promoting aggregation of the Peorian loess. It was found that inoculation with S. atra could greatly increase the aggregation of fumigated Peorian loess in treatments where the …
