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 …

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 …

Arkansas Cotton Variety And Strain Tests 1991, F. M. Bourland, J. S. Dacus

Arkansas Agricultural Experiment Station Research Series

Varieties and advanced strains of cotton were evaluated in 1991 by the Arkansas Agricultural Experiment Station. Varieties and some advanced breeding lines were evaluated in the 1991 Arkansas Cotton Variety Test. Entries in the 1991 Commercial Cotton Strain Test included both released varieties that have not been evaluated in Arkansas and advanced breeding lines that may soon be available to producers.

Jasmonate, Genes, And Fragrant Signals, Paul E. Staswick

Department of Agronomy and Horticulture: Faculty Publications

Although first recognized for its growth-inhibiting activity about 20 years ago, JA² and its fragrant methyl ester MeJA (referred to here collectively as jasmonate) are receiving renewed interest as potentially important signaling molecules in plants. This is because jasmonate markedly increases the expression of specific plant genes, some of which are wound responsive. Similarities with fatty acid-derived stress signaling molecules in animals (1) make jasmonate of general biological interest.

Corn Response To Zinc On High Ph Soils, William O. Thom, James E. Dollarhide, Jeff Henderson, Vern Case

Agronomy Notes

Corn is the most responsive to zinc of all agronomic crops grown in Kentucky. Zinc deficiency can occur most often in soil of the Inner Bluegrass and in south central Kentucky. This deficiency is most likely when these soils have a high pH, although such factors as high phosphorus, low organic matter, and loss of topsoil through erosion or construction can increase deficiency symptoms. Also, zinc deficiency is more prevalent during a cool, wet spring with symptoms often disappearing when the soils become warmer and drier. Zinc is a very immobile element, thus roots must grow throughout the root zone …
