Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney

Bulletins 4000 -

Vegetable growers need to use fertiliser efficiently. Under-fertilising can reduce yield, which results in economic losses. Over-fertilising can reduce yield and contribute to nitrogen and phosphorus pollution of ground and surface waters. Concerns have been expressed that fertilisers applied to horticultural crops contribute to the phosphorus pollution of the rivers and estuaries of the west and south coast of Western Australia.

Soil testing is a technique that can be used by growers to make better fertiliser decisions. When soil tests show high levels of nutrients, growers can reduce fertiliser application for the current crop. This should enable growers to maintain …

Yield, Earliness And Fiber Strength Of Blends Of Cotton (Gossypium Hirsutum L.) Cultivars, J. S. Mcconnell, F. M. Bourland, W. H. Baker, B. S. Frizzell

AAES Research Reports and Research Bulletins

Pricing of cotton (Gossypium hirsutum L.) has been determined primarily by fiber length and grade, which were manually determined. Implementation of the high volume instrument (HVI) cotton classing system in 1991 allowed other fiber quality parameters to be objectively and rapidly measured (Deussen, 1989). One quality parameter added to the pricing structure by the advent of HVI in determining the value of ginned lint is fiber strength (Table 1). Open-end spinning, a new technology being utilized by the textile industry, requires high-strength cotton fibers (>25 g/tex) for manufacture of yarns. As this technology becomes more widely used, cotton with …

Soil Temperature And Fumigation Effects On Plant Phosphorus Uptake And Related Microbial Properties, Dennis L. Mccallister, L. A. Jawson, M. D. Jawson

Department of Agronomy and Horticulture: Faculty Publications

Early season problems with growth of corn (Zea mays L.) under cool, wet conditions prompted a study of the effects of soil and environmental conditions on mineralization and plant uptake of phosphorus (P). Our objective was to determine the effect of soil test P, temperature, and soil fumigation on soil P availability and uptake during early corn growth. Corn was grown in growth chambers at temperatures of 14°C or 25°C. Soils were a high-P Hastings silty clay loam (fine, montmorillonitic, mesic Udic Argiustoll) and a low-P Sharpsburg clay loam (fine, montmorillonitic, mesic Typic Argiudoll). Plants grew for up to …

Notes: Forage Yield, Quality, And Fertility Of Sorghum X Sudan Grass Hybrids In A1 And A3 Cytoplasm, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Currently, no information is available comparing the agronomic performance of A1 and A3 cytoplasms in sorghum x sudangrass [Sorghumbi color (L.) Moench] hybrids. The objectives of this study were to compare the effects of A1 and A3 cytoplasm on the maturity, fertility, height, forage yield, and forage quality of sorghum × sudangrass hybrids. In 1989, pollen from a bulk of eight sudangrass populations was used to pollinate four sorghum lines that had been male-sterilized in both A1 and A3 cytoplasm. Hybrids were grown at the Univ. of Nebraska Field Laboratory Ithaca, NE, in 1990 and 1991, in a split-plot …

Molecular And Functional Characterization Of A Novel Low-Affinity Cation Transporter (Lct1) In Higher Plants, Daniel P. Schachtman, Raman Kumar, Julian I. Schroeder, Ellen L. Marsh

Department of Agronomy and Horticulture: Faculty Publications

The transport of cations across membranes in higher plants plays an essential role in many physiological processes including mineral nutrition, cell expansion, and the transduction of environmental signals. In higher plants the coordinated expression of transport mechanisms is essential for specialized cellular processes and for adaptation to variable environmental conditions. To understand the molecular basis of cation transport in plant roots, a Triticum aestivum cDNA library was used to complement a yeast mutant deficient in potassium (K⁺) uptake. Two genes were cloned that complemented the mutant: HKT1 and a novel cDNA described in this report encoding a cation …

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1995 , Arkansas Agricultural Experiment Station Research Series 450. 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.

Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones

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

In 1993, western flower thrips, an important pest of horticultural crops, was found in Western Australia. Since then there has been an upsurge in damsging virus disease epidemics caused by tomato spotter wilt virus in horticultural crops. This has occurred because western flower thrips is a more effective vector of tomato spotted wilt virus than other thrips species. Lindrea Latham and Roger Jones outline the symptoms, spread and management of this serious virus disease in vegetables and ornamentals.

Application Of The Single Kernel Wheat Characterization Technology To Sorghum Grain, Jeffrey F. Pedersen, C. R. Martin, F. C. Felker, J. L. Steele

Department of Agronomy and Horticulture: Faculty Publications

A single kernel wheat characterization system (SKWCS) was recently developed by the USDA, ARS Grain Marketing Research Laboratory and is currently being marketed by Perten Instruments North America, Inc. This device has been shown to accurately measure individual seed hardness, moisture, and size of wheat. The objective of this study was to determine if the SKWCS technology could be applied to the measurement of sorghum grain. Grains from 64 sorghum plots grown at Mead, NE in 1992 were characterized using a prototype SKWCS at the USDA, ARS Grain Marketing Research Laboratory. Problems encountered were primarily associated with the single kernel …

Annual Forages: New Approaches For C-4 Forages, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

The current agricultural paradigm in the U.S. is heavily biased towards the production and marketing of crops as commodities. This paradigm is kept in place by grain handling and marketing infrastructure, as well as government farm programs, designed for crops as commodities. Sorghum (Sorghum bicolor L. Moench) and maize (Zea mays L.) grown for grain certainly fit into this current paradigm.

A new approach to agricultural production and marketing, identity preserved products, is gaining in importance. This is made possible through new technologies and markets demanding products designed specifically for their needs. Examples of investment in identity preserved …

Media Effects On Phenotype Of Callus Cultures Initiated From Photoperiod-Insensitive, Elite Inbred Sorghum Lines, H. F. Kaeppler, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Sorghum (Sorghum bicolor L. Moench) is a crop of worldwide agronomic importance. Routine production of high quality (friable, embryogenic, fast growing) callus cultures is fundamental to tissue culture based genetic study and improvement of sorghum. Genotype by culture medium interactions for sorghum callus growth and morphology have been previously reported. The objective of this study was to identify tissue culture media that would support high quality callus growth across photoperiod insensitive, relatively elite genotypes. Explants from immature inflorescences of 11 sorghum genotypes were cultured on 6 tissue culture media of differing composition. After 3 and 5 months in culture, calli …

Germplasm And Cultivar Development, M. D. Casler, Jeffrey F. Pedersen, G. C. Eizenga, S. D. Stratton

Department of Agronomy and Horticulture: Faculty Publications

Cool-season forage grasses have evolved, and continue to evolve, in natural ecosystems subject to environmental factors both in the presence and absence of human influences. The literature often lacks facts describing the evolution and domestication of forage grasses. Furthermore, the literature on this subject mainly deals with evolution of species in the broad scope, i.e., on a scale of hundreds of thousands or millions or years. Thus, some of our conclusions are necessarily speculative and are highly subject to the nature of the research that has been reported. We describe the forces of selection that act upon cool-season forage grasses …

Breeding Sorghum And Pearl Millet For Forage And Fuel, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Sorghum [Sorghum bicolor (L.) Moench] and pearl millet [Pennisetum glaucum (L.) R. Br.] are unique species in their ability to be used in many forage llivestock system roles. Such flexibility has made prioritizing breeding objectives difficult and has even contributed to contradictory opinions on appropriate forage breeding objectives. Few breeding projects identified in the USDA-ARS, USDA-CREES, or at ICRISAT had forage sorghum or forage pearl millet as their sole research assignment. In the United States, it can be argued that breeding resources committed to forage sorghum improvement are probably declining. A new forage sorghum and forage pearl millet …
