Plant pathogenic fungi cause important yield losses in crops. In order to develop efficient and environmental friendly crop protection strategies, molecular studies of the fungal biological cycle, virulence factors, and interaction with its host are necessary. For that reason, several approaches have been performed using both classical genetic, cell biology, and biochemistry and the modern, hol...

Nitrogen is the plant nutrient required in the largest quantity, the most likely to be deficient, and the most impactful on corn yield as well as grower profit. Providing N to a corn crop in the right amount while minimizing loss is difficult because of complex biological and chemical reactions that result in the loss of N from the crop root zone via deep percolation to ground water, lateral fl...

In order to develop efficient and environment-friendly crop protection strategies, molecular studies of the fungal biological cycle and interaction with its host are necessary. For that reason, several approaches have been made using both classical genetic, cell biology and biochemistry and modern, holistic and high-throughput, omic ...

Peanuts receive major emphasis because of the crop's importance to the economy of southeastern Virginia and the magnitude of pesticide use in crop management. In 1992, growers planted 93,000 acres of the crop and harvested an estimated 123,225 tons of peanuts with a value of ca. 79 million dollars in farm income. When coupled with the shelling, processing and shipping industries in the Tidewate...

Annual loads of nitrogen and phosphorus from the Baltic drainage area to the Baltic Sea in 1995 are estimated at 761 000 and 37 500 Mg, respectively. In Sweden it has been estimated that human activities account for 54% of the annual input of nitrogen and 55% of the annual input of phosphorus to the Baltic Sea. Agreements to halve the quantity of nutrients reaching the marine environment by 199...

Power, J.F., Wilhelm, W.W. and Doran, J.W., 1986. Crop residue effects on soil environment and dryland maize and soya bean production. Soil Tillage Res., 8 : 101-111. The research reported here provides data on the effects of crop residues o n the surface of no-till soil upon the soil environment and resulting biological activity, including crop growth. For maize (Zea mays L.) and soya bean [Gl...

There has been renewed interest in the application of endophytic fungi to control phytopathogenic fungi, which cause significant damage crop health, ultimately leading losses agricultural productivity. Endophytic inhibit pathogens via different modes action—mycoparasitism, competition (for nutrients and ecological niches), antibiosis, induction plant defense—thus demonstrating ability a wide ra...

Phosphorus (P) and suspended sediment (SS) play a pivotal role in influencing water quality and biodiversity and, as a result, controlling the transfer of these important diffuse pollutants from land to water, represents a priority task for catchment managers and stakeholders (Kronvang et al., 2005a). This review briefly summarises the environmental and legislative context regarding phosphorus ...

Crop improvement is a multifaceted micro-evolutionary process, involving changes in breeding approaches, planting configurations and consumption preferences of human beings. Recent research has started to identify the specific genes or genomic regions correlate to improved agronomic traits, however, an apparent blank between the genetic structure of crop elite varieties and their improving hist...
