Visions For Agriculture, Department Of Agriculture, Western Australia

Agriculture reports

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Utilizing Iron In Turfgrass Management, David J. Wehner

Office of the Dean (CAFES) Scholarship

The purpose of this article is to review some of the basic information on iron, look at one of the discoveries made during the 1980s, and present some of the published research studies that have been conducted with iron on turfgrasses. Additional information on the use of iron can be found in popular magazines and in the proceedings of turfgrass conferences.

Diversity Among Rhizobia Effective With Robinia Pseudoacacia L, Janet Mccray-Batzli, William R. Graves, Peter Van Berkum

William R Graves

The diversity of rhizobia that form symbioses with roots of black locust (Robinia pseudoacacia L.), an economically important leguminous tree species, was examined by inoculating seedling root zones with samples of soil collected from the United States, Canada, and China. Bacteria were isolated from nodules, subcultured, and verified to be rhizobia. The 186 isolates varied significantly in their resistance to antibiotics and NaCl, their growth on different carbohydrates, and their effect on the pH of culture media. Most isolates showed intermediate antibiotic resistance, the capacity to use numerous carbohydrates, and a neutral to acid pH response. Isolates had greater similarity …

Growing Soybean Varieties From Multiple Maturity Groups Can Reduce Yearly Yield Volatility, Todd W. Pfeiffer

Agronomy Notes

In the Kentucky Soybean Performance Test program, varieties of maturity groups (MG) 3, 4 and 5 are tested to provide information on their relative yields. The difference in maturity between the earliest and the latest maturing variety in the test in any year is approximately 30 days. In general, although some regional differences appear, the long-term state-wide and within region yield of the different maturity groups (average yield of a 11 varieties in a maturity group) is equal (Table 1). As I've inspected results from the Kentucky Soybean Performance Tests for the last decade, it appeared that some of the …

Arkansas Rice Research Studies 1991, 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 1991, Arkansas Agricultural Experiment Station Research Series 421. 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.

Trends In Cropland Acreage And Fertilizer Use In Kentucky Since 1980, Kenneth L. Wells

Agronomy Notes

Cropland acreage and patterns of fertilizer use varied considerably during the period 1980-1991. Variation in cropland acreage is largely related to commodity prices, available markets, land ownership patterns, and government programs. Patterns of fertilizer use are affected by cropland acreage, the nature of the fertilizer supply industry in Kentucky, weather, and improved efficiency in use of time and labor by farmers. The situation in the early 1990's is different than it was in 1980, and the following discussion highlights changes that have taken place. Fertilizer use data are those reported by the University of Kentucky's Division of Regulatory Services in …

No-Tillage Seeders And Their Adoption In North America With Relevance To Western Australia, J K. Bligh

Resource management technical reports

The adoption of no-tillage seeders appears generally to be at a similar stage in North America as in Western Australia. One notable difference is the communication provided by several no-tillage farmers organisations, such as the Manitoba-North Dakota Zero Tillage Farmers Association. Since almost all development of no-tillage systems has been carried out by farmers, such associations have proven invaluable in directly providing communication with their peers.

Herbicide Trials On Field Crops 1991, Robert Frans, Marilyn Mcclelland, David Jordan

Arkansas Agricultural Experiment Station Research Series

Herbicidal weed control is economically important for production of field crops. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental ancommercial herbicides for selective control of weeds in several important crops. These experiments serve both industry and Arkansas agriculture by providing information on the selectivity of herbicides still in the developmental stage and by comparing the activity of these new herbicides with that of recommended herbicides.

Quest For Quality Operation Quality Wheat, Sue Bestow

Agriculture reports

Variations in the protein content of wheat are largely associated with growing conditions, particularly rainfall and soil type, which influence nitrogen supply and crop yield. Management to improve protein generally also improves yield, so in future both must be considered when comparing profitabilities of management options, particularly if payment for protein increases.

An Early-Planted, Early Maturing Soybean Cropping System: Yield And Harvest Losses, Larry J. Grabau, M. V. Kane, H. Lin, Dennis B. Egli

Agronomy Notes

Most soybean varieties used In Kentucky, whether grown full season or double-cropped behind wheat or barley, are from Maturity Groups (MG) IV or V. Some MG III varieties are also grown; however, virtually no MG 1/ or earner varieties are planted. Agronomists and soybean producers in Kentucky· have generally felt that MG IV and V varieties produce the highest yield. Since the driest months in Kentucky are August, September,and October, MG IV and V varieties frequently encounter moisture stress during the important seed fill stage. The use of earlier maturing varieties was initially proposed as a means of getting a …

Stubble Retention For Control Of Wind Erosion, Dan Carter, Paul Findlater, Steve Porritt

Domestication Of Rough-Seeded Lupins, Bevan Buirchell, Wallace Cowling

Since the beginning of civilisation, humans have been domesticating wild plants such as wheat, barley and rice. They have both conciously and unconciously selected plant types suited to cropping.

Reccently, there has been an increasing effort to domesticate a greater variety of wild plants, especially legumes.
