Arkansas Soybean Research Studies 2020, Jeremy Ross

Arkansas Agricultural Experiment Station Research Series

The 2020 Arkansas Soybean Research Studies includes research reports on topics pertaining to soybean across several disciplines from breeding to post-harvest processing. Research reports contained in this publication may represent preliminary or only data from a single year or limited results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication will appear in other University of Arkansas System Division of Agriculture’s Arkansas Agricultural Experiment Station publications. This duplication is the result of the overlap in research coverage between disciplines and our effort to inform Arkansas soybean producers of the research …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner

Honors Projects

The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species⁴. RNA-seq analysis showed that one gene, PPTG_16698 has the 5^th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of …

Bulletin No 3861 - Kimberley Research Station - Progress Report 1972, J. R. Mcalpine, R. H. Gunn, P. Jakobsen, R. Wetselaar, J. J. Basinski, N. J. Thomson, A. G. L. Wilson, D. H. Mackenzie, A. J. Millington, D. F. Beech, P. C. Owen, B. G. Williams, C. G. Blunt, A. Mcr Holm

Bulletins - 3000 - 3999

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 …

Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell

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

FARM experience and the results of five years intensive research have shown copper deficiency to be widespread in the south-eastern wheatbelt.

On many areas of the south-eastern wheatbelt, copper deficiency is likely to restrict wheat yields.

Growing Barley For Grain In Western Australia : Barley Quality, J A. Parish

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

Plumpness and absence of pinched grain are desirable for both malting and feed barley.

This is a brief discussion of various Quality standards in barley and how they may not be met.

Controll Of Eelworm Diseases Of Bananas In Western Australia : A Review, O M. Goss, M. G. Hawson

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

During the 1950's, a decline in bananas in plantations in Carnarvon, caused by heavy infestations of eelworms, prompted investigations into eelworm control.

The work was started in 1955. The results and recommendations based on experiments have been published in Department of Agriculture Bulletin 3532.

Linseed : An Alternative Crop For The South Coast, R J. Doyle, R. J. Guyton

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

IN the over-17 inch rainfall zone of the south coast region of Western Australia animal production is the main farm enterprise.

Although farmers in the main cereal growing regions of W.A. crop about one-third of their cleared land each year, farmers in the south have been reluctant to crop more than about 12 per cent, of their cleared area.

The 1965 Ord River Cotton Crop, G D. Oliver, A. W. Hogstrom

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

THE financial results of 18 cotton growers in the Ord River Valley during the 1965 season were obtained during a survey conducted in August, 1965.

All farmers who have been allocated blocks and who grew cotton in 1965 were included in the survey.*

Take-All Of Wheat On The Esperance Downs : The Effect Of Multiple Cropping, S C. Chambers

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

A considerable increase in take-all occurred in the second crop of wheat following linseed, oats or vetches at the Esperance Downs Research Station.

THE take-all disease of wheat, caused by the fungus Ophiobolus graminis, has been responsible for many crop failures in the Esperance district during the past 15 years.

In an endeavour to find a practical solution to this problem, a crop rotation experiment was started in 1961 at the Esperance Downs Research Station.

Root Diseases In Wheat On Clover Ley : Factors Under Investigation. 5. The Evaluation Of Fungicidal Treatments, S C. Chambers

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

The use of fungicides, either as seed or soil dressings, for the control of root rotting diseases of wheat, was examined in a series of field experiments.

Results suggest that seed dressings have no effect on the incidence of root rotting fungi in the mature crop.

When fungicides were applied to the soil, a reduction in the incidence of take-all was noted in one experiment, but the same treatments had toxic effects on plants in a second similar experiment.
