Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom May 2019

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U.S. By addressing …


Estimating Crop Yield Potential At Regional To National Scales, Justin Van Wart, Kurt Christian Kersebaum, Shaobing Peng, Maribeth Milner, Kenneth Cassman Jan 2013

Estimating Crop Yield Potential At Regional To National Scales, Justin Van Wart, Kurt Christian Kersebaum, Shaobing Peng, Maribeth Milner, Kenneth Cassman

Department of Agronomy and Horticulture: Faculty Publications

World population will increase 35% by 2050, which may require doubling crop yields on existing farm land to minimize expansion of agriculture into remaining rainforests, wetlands, and grasslands. Whether this is possible depends on closing the gap between yield potential (Yp, yield without pest, disease, nutrient or water stresses, or Yw under water-limited rainfed conditions) and current average farm yields in both developed and developing countries. Quantifying the yield gap is therefore essential to inform policies and prioritize research to achieve food security without environmental degradation. Previous attempts to estimate Yp and Yw at a global level have been too …

Positive Price Outlook For Wheat : Implications For Wa Agriculture, Alan Haagensen, Ian Wilkinson Jan 1996

Positive Price Outlook For Wheat : Implications For Wa Agriculture, Alan Haagensen, Ian Wilkinson

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

After a 40 year period over which wheat prices have dropped by an average of 2.7 per cent annually in real terms, fundamental changes in wheat supply and demand look set to reverse this trend. It is possible that real prices could increase by as much as 4 per cent anually in the medium term.

Alan Haagensen and Ian Wilkinson look at the forecasts for wheat prices and outline the forces that will influence world supply and demands for wheat.


Production Of High-Value Wheats : One Sustainable Answer To The Cost:Price Squeeze, Wal Anderson, Alan Peggs, Doug Sawkins Jan 1993

Production Of High-Value Wheats : One Sustainable Answer To The Cost:Price Squeeze, Wal Anderson, Alan Peggs, Doug Sawkins

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

Farmers and scientists alike over the past decade have sought to address the declining terms of farm trade (the cost.price squeeze) by increasing wheat yields in ways that will ensure both their economic and ecological survival. Nevertheless, costs have continued to increase as a proportion of the value of the product.

Many farmers have increased their wheat yields substantially and the industry as a whole is more conscious of the quality of its product.

Over the past 10 years or more there has been intense interest in, and considerable adoption of. conservation farming techniques such as minimum tillage, residue retention, …


The Productivity Of Western Australia's Wheat And Sheep Industry, Tim Coelli, Ross Kingwell Jan 1991

The Productivity Of Western Australia's Wheat And Sheep Industry, Tim Coelli, Ross Kingwell

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

A popular economic lament is that Australian industries and workers are not as productive as they should be. Politicians and economic commentators preach the need for productivity improvement and workplace reform, and criticise inefficiency and lack of endeavour. Can such criticism be fairly levelled at farmers and agricultural scientists? What is productivity and how is it measured? What is the productivity of Western Australia's main agricultural industry — wheat and sheep farming? This article addresses these questions and shows that our wheat-sheep industry can be moderately proud of its productivity record


Wheat Payments And Protein Content, Department Of Agriculture, Western Australia Jan 1987

Wheat Payments And Protein Content, Department Of Agriculture, Western Australia

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

In recent years there has been increasing support from within the Australian wheat industry for the principal of wheat growers recieving payment for their grain according to market value.

Individual loads are now tested for quality characteristics such as hectolitre weight, unmillable material and moisture content.

At present, technology is not sufficiently advanced to enable rapid and accurate analysis of individual loads for all important quality factors.

A more practical system of quality assessment would be one based on allowances for various basic measures (such as hectolitre weight, unmillable material and moisture content), variety (to allow for genetic differences in …

Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes

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

INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.

It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.

Take-All Of Wheat On The Esperance Downs : The Effect Of Multiple Cropping, S C. Chambers Jan 1964

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.
