Arkansas Rice Research Studies 1992, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1992, Arkansas Agricultural Experiment Station Research Series 425. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Life History And Description Of Immature Stages Of Procecidochares Stonei Blanc & Foote On Viguiera Spp. In Southern California (Diptera: Tephritidae), John F. Green, David H. Headrick, Richard D. Goeden

Horticulture and Crop Science

Procecidochares stonei Blanc & Foote is a facultatively multivoltine, stenophagous, gall-forming fruit fly on Viguiera laciniata Gray and V. deltoidea Gray var. parishii (Greene) Vasey and Rose (Asteraceae) in southern California. The latter host record is new; other published host records are questioned. Eggs, first through third instar larvae, and puparia are described for the first time. Galls formed on both host plants are described. The severe drought in southern California during the last 5 years has reduced the densities of P. stonei on V. d. var. parishii. Fly reproduction was restricted to one generation per year on the few …

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 …

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 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

Eradication Of Apple Scab, John Cripps, Ralph Doepel

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

The detection of apple scab in two orchards at Pemberton and New/ands in December 1989 ended Western Australia's 41-year, scab-free span for apple growers .

Without eradication orchardists would have had to apply up to 20 fungicidal sprays a year, at an annual cost of $1-2 million, to be able to market a high proportion of scab-free fruit. The industry chose eradication as the cheaper alternative, but the location of infected orchards at Pemberton in particular, with its high rainfall, suggested that it would be difficult .

Scab, or black spot, is the most serious fungal disease of apples in …

Addition Of Gel-Forming Hydrophilic Polymers To Nitrogen Fertilizer Solutions, Robert Mikkelsen, A David Behel

Robert Mikkelsen

Environmental and economic concerns are causing a search for more effective fe rtilizer products and improved methods for managing existing fertilizers. This laboratory and greenhouse study was conducted to determine if the addition of gel-forming hydrophilic polymers to N fertilizer solutions could reduce N leaching loss and increase plant uptake of N. In the first experiment, a solution of urea ammonium nitrate (UAN, 32% N) was mixed with a variety of polymers at three concentrations, band applied to a sandy soil, and leached weekly for six weeks. Nitrogen leaching losses were reduced from 0 to 45% during the first four …

Controlled-Release Fertilizers To Increase Efficiency Of Nutrient Use And Minimize Environmental Degradation - A Review, Avi Shaviv, Robert Mikkelsen

Robert Mikkelsen

Total world consumption of fertilizer N, P2 O5, and K2O in 1990 / 1991 was 78. 37. and 26 million tons per annum respectively, with a projected yearly increase of demand of about 2 to 3% . Trends in crop production (maize and wh eat) in the last four decades s how that N application rates increased about 15 times whereas its accumulation in grain increased only 3 to 4 times. At the same time nutrient recovery by crops remained relatively low (e .g. a bout 50% for N). This represents a potentially alarming situation from environmental, economic and resource …

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 …
