Planting date and seed treatment effects on soybean in the northeastern United States
Soybean [Glycine max (L.) Merr.] production is limited in the northeastern United States so research on optimum planting date is scarce. Soybean production in this region may increase because of biodiesel demand so we initiated a 2-yr study in New York that compared soybean planting dates with and without seed-applied fungicide/insecticide treatments. Soybean planted in mid- compared with late ...

Retail survey of brazilian milk and minas frescal cheese and a contaminated dairy plant to establish prevalence, relatedness, and sources of listeria monocytogenes isolates
A study was designed to recover Listeria monocytogenes from pasteurized milk and Minas frescal cheese (MFC) sampled at retail establishments (REs) and to identify the contamination source(s) of these products in the corresponding dairy processing plant. Fifty milk samples (9 brands) and 55 MFC samples (10 brands) were tested from REs located in Juiz de Fora, Minas Gerais, Brazil. All milk samples ...

Canopy nitrogen reserves: impact on soybean yield and seed quality traits in northern latitudes
Soybean [Glycine max (L.) Merr.] seed produced in the upper Midwest of the United States is lower in protein concentration than soybean produced throughout much of the Corn Belt, the southern United States, and Brazil. As protein comprises on average more than 400 g kg–1 of the soybean seed, yields in northern latitudes may be limited by seed protein accrual. Our objective was to examine the role ...

Interactive effects of carbon dioxide and water stress on potato canopy growth and development
Reductions in potato (Solanum tuberosum L.) canopy growth are observed with mild water stress. Potato growth is enhanced by elevated atmospheric carbon dioxide ([CO2]), but interactions of [CO2] and water stress on canopy formation and dry matter partitioning have not been studied. Two soil-plant-atmosphere research (SPAR) experiments were conducted at 370 or 740 µmol mol–1 [CO2] and six ...

Summer–fall seeding dates for six cool-season grasses in the midwest united states
The effect of late summer (fall) planting date for cool-season grasses in the upper Midwest is not well understood. Objectives of this research were to determine optimum planting dates of late-summer/fall seedings in different environments for several cool-season grass species and to gain information on tiller density and tillers plant–1 relative to dry matter yield. Late-summer/fall seedings of ...

Tissue-specific expression of rice CYP72A21 induced by auxins and herbicides
Cytochrome monooxygenase P450s (CYPs) comprise one of the largest enzyme families in plants. Some P450s are involved in xenobiotic metabolism: they confer herbicide tolerance and are induced by chemical treatments. We isolated a novel P450 cDNA, CYP72A21 (accession number, AB237166), from rice (Oryza sativa L. cv. Nipponbare) seedlings treated with a mixture of 2,4-dichlorophenoxyacetic acid ...

An overview of preharvest factors influencing postharvest quality of horticultural products
Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

Microbial communities of Solanum tuberosum and magainin-producing transgenic lines
Antimicrobial peptide magainin II, isolated from the skin of the African clawed toad, has shown activity in vitro against a range of micro-organisms. Transgenic potato lines expressing a synthetic magainin gene show improved resistance to the bacterial plant pathogen, Erwinia carotovora. Culturable bacterial and fungal communities associated with magainin-producing potato plants were compared ...

Omaha beach golf course
The rich green swathes of the new extension of Omaha Golf Course are visual proof of high technol¬ogy at its best, enabling lush ungated grass to survive all year round despite being bordered on two sides by ocean and estuary and buitt on a combination of sand dunes and wetlands. It is a world first, and an international success story for the three main players - local drainlayer Ivor Jones, ...

Two Cases of Misleading Environmental Declarations Due to System Boundary Choices
Abstract Environmental Product Declarations (EPDs) on electricity and nitrogen fertiliser are used to illustrate how a declaration or labelling* based on data from the current supply chain can be misleading when the production capacity in the supply chain is constrained. Three ways of avoiding such misleading declarations are suggested. Introduction: The cause of deception As a specific ...

Compost stability: a comparative evaluation of respirometric techniques
The new Paradigm in waste management promotes attitudes and processes that conserve resources and reduce pollution. Under this philosophy, organic waste is increasingly recognised as a recyclable material, a useful resource, making composting one of the key elements of modern waste management. As the composting industry is expanding rapidly there is a growing need for a simple, fast, relatively ...
