Export Of Rockmelons From The Ord River, John Bonnardeaux

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

The Ord River Irrigation Area and Carnarvon are the main production areas for cucurbits in northern Western Australia. Cucurbits are also grown in Derby, Broome and around Lagrange, south of Broome.

The area planted to rockmelons in the Ord River Irrigation Area has increased from 20 ha in 1980 to 425 ha in 1992.

Rockmelon production, the most important horticultural industry in the Ord River Irrigation Area, is worth about $9 million. It accounts for about 25 per cent of the Ord's dry season value of production

Production And Marketing Of Vegetables And Fruit, John Burt

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

Vegetable and fruit production in Western Australia is a diverse, high value industry. Up to 75 different crops are grown from Kununurra in the north to Albany on the south coast.

Our horticultural industries were worth $238,127,000 in 1990-.91, which represented 18 per cent of all crops produced in Western Australia.

Markets for horticultural produce are volatile. For most lines, produce has been well supplied for the past four years, owing to an increasing area of production, higher yields, improved postharvest technology and reduced consumer demand in the recent recession.

Bulletin 4247 - Introduction To Commercial Mushroom Growing, Margaret Graham

Bulletins 4000 -

Mushroom cultivation began in Australia in the 1930s in the then incomplete and unused Circular Quay railway tunnel in Sydney. In the 1950s most mushrooms were grown in heaped or 'ridge-beds' of compost in disused railway tunnels.

In the last 15 to 20 years there has been considerable technical change in the method and degree of sophistication of mushroom cultivation techniques. Most growers have invested large sums of capital in specially designed and insulated buildings that control temperature, humidity and ventilation and where pest and disease prevention and control is less difficult.

The bag method also helps to alleviate pest …

The Export Carrot Industry, Angie Galati, Allan Mckay

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

Carrots are the single most important horticultural export commodity from Western Australia.

In 1991-92, over 23,000 tonnes of carrots worth more than $12 million (fob) were exported. The State now exports about 70 per cent of its carrot production to Singapore, Malaysia, Hong Kong and the Middle East (see Table 1). These exports account for more than 90 per cent of Australian carrot exports. The State's carrot exports started in the mid 1970s. In 1977-78, only 2170 tofcarrots were exported, but exports have increased steadily since then (see Figure 1).

Export Of Asparagus From The Ord River, John Bonnardeaux, Chris Robinson

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

Fresh asparagus is presently supplied to Australian markets from August to March from temperate regions. For the remainder of the year, there is no significant production of fresh spears in Australia.

Recent research in Taiwan, Zambia and Zimbabwe has indicated quality asparagus can be grown in tropical and subtropical regions. The harvest period can be manipulated by withholding irrigation water and cutting fems to make spears grow out-of-season.

Developmental Morphology Of Tropical Sorghum And Sorghum X Sudangrass, R. B. Mitchell, K. J. Moore, Jeffrey F. Pedersen, T. A. Peterson, L. E. Moser, D. D. Redfearn

Department of Agronomy and Horticulture: Faculty Publications

Tropical sorghum and sorghum x sudangrass are known to be efficient scavengers of soil nitrogen and are important forage crops in the U.S. Nitrate contamination of groundwater due to disposal of organic wastes and excessive fertilization is a major concern in the Central Great Plains. A common disposal method of municipal wastes is application to fallow cropland. Quantification of the developmental morphology of tropical sorghum and sorghum x sudangrass is important to developing management strategies that allow multiple applications of organic wastes to optimize nitrogen removal and dry matter production. The objective of this study was to quantify the developmental …

Genetic Manipulation Of Tall Fescue, Jeffrey F. Pedersen, D. A. Sleper

Department of Agronomy and Horticulture: Faculty Publications

Genetic manipulation of tall fescue (Festuca arnndinacea Schreb.) has not been altered by the discovery of the Acremonium coenophialum (Morgan-Jones and Gams) / grass interaction. However, tall fescue breeding programs have been affected greatly. The basic methods for genetically manipulating the grass have remained static. Tall fescue is an obligate out-crossing species, and most improvements are, therefore, captured in the form of an improved population developed through some form of mass or recurrent selection. What has changed is the breeder's ability to recognize genetic differences in the grass because of the confounding effect of A. coenophialum on plant phenotype. It …

Comparison Of Sorghum And Indiangrass Chloroplast Genomes Using Rflps, Jeffrey F. Pedersen, R. D. Lee, D. J. Lee, K. P. Vogel

Department of Agronomy and Horticulture: Faculty Publications

Sorghum (Sorghum bicolor (L.) Moench) and indiangrass (Sorghastrum nutans (L.) Nash) appear closely related based on morphological and chemotaxonomic characters. Each species could potentially provide desirable traits to the other. However, traditional breeding techniques have been unsuccessful in hybridizing these two species. The objective of this study was to determine the relatedness of sorghum and indiangrass chloroplast DNA using RFLPs. Eleven sorghum lines in several cytoplasms, two indiangrass popu1ations, and a corn line were studied using 60 proberestriction enzyme combinations. Principal component analysis of the results showed sorghum to be as closely related to corn as to indiangrass, with no …

Mango Exports From Western Australia, Peter Johnson, John Gallagher, Terry Hill

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

The Department of Agriculture has been at the forefront in developing a mango industry in Western Australia.

In Camarvon, the Department is concentrating on developing an export industry, while in the Ord River Irrigation Area trials have identified suitable domestic and export varieties for that environment.

The effect of planting density, hedging and pruning techniques on yield is being examined. Research has also started on identifying superior selections of the Kensington Pride variety, the most commercially important variety in Australia. The aim is to improve fruit quality, bearing reliability, and to extend the production season..

Bulletin 4256 - Pecan Nut Cultivation, Aldo Labrosciano

Bulletins 4000 -

Pecans Carya illinoensis, an indigenous species to Northern America, are successfully grown between the latitudes of 25° and 35°. There is considerable variation in size and flavour of the 1000 or more varieties of the nuts.

Large scale production is concentrated in north America, Israel and South Africa. Plantings in Australia are in Victoria and New South Wales, and are developing slowly in Western Australia.

Pecans are well suited to Western Australian conditions where the soil is well drained. Though the trees are deciduous, they have no chill requirement and will flourish if water is not limiting.

Life History And Description Of Immature Stages Of Aciurina Thoracica (Diptera: Tephritidae) On Baccharis Sarothroides In Southern California, David H. Headrick, Richard D. Goeden

Horticulture and Crop Science

Aciurina thoracica Curran forms galls on branches of at least three species of Baccharis in southern California. The egg, second and third instars, and puparium obtained from B. sarothroides Gray are described and illustrated. Aciurina thoracica's median oral lobe is described and illustrated. The egg is inserted singly into branch tips of B. sarothroides in early spring. Gall and larval growth continue through summer and fall, and pupariation occurs in early winter. Adults emerge in late winter or early spring, mate, and oviposit into newly forming branch tips. Adult behavior including courtship and copulation is described and compared with other …
