Crops that are not part of the customary diet of the local population and grown primarily for their high cash values and export potentials are categorized as nontraditional. Recently, several African countries have gone into the production of nontraditional fruits and vegetables of temperate origin in order to diversify their agricultural exports and increase hard currency earning. Most develop...

lehmannia valentiana is one of the most important pests of ornamental plants, vegetables and other agricultural crops, which causes noticable damages. in a food experiment four kinds of food for 24 and 72 hours were offered. the preferences of food were amaranthus tricolor, cineraria grandiflora, pelargonium peltatum, rosa damascena and l. valentiana. the l. valentiaiia is active the whole year...

Despite its association with important agricultural crops, Phytophthora clade 8b is a poorly studied group of species. The clade currently consists of three officially described species (Phytophthora porri, P. brassicae and P. primulae) that are host-specific pathogens of leek, cabbages and Primula spp., respectively. However, over the past few decades, several other clade 8b-like Phytophthoras...

The consumption of crops fertilized with human waste represents a potential route of exposure to antibiotic-resistant fecal bacteria. The present study evaluated the abundance of bacteria and antibiotic resistance genes by using both culture-dependent and molecular methods. Various vegetables (lettuce, carrots, radish, and tomatoes) were sown into field plots fertilized inorganically or with cl...

The content of nitrates and nitrites in agricultural products has been assessed as an indicator of the quality of the products and has important health influences 1. Changes in patterns of agricultural practice, food processing and industrialization have impacted accumulation of nitrates/nitrites in the environment. Intensive farming practice has resulted in an increasing use of nitrogen-based ...

Intergovernmental Panel on Climate Change (IPCC) reported that the global mean temperature had risen for the 20th century at the rate of 0.74oC per 100 years due to increasing green house gas. Climate change such as temperature, precipitation and tropical cyclone activity has been strongly related to agricultural production, water resource, and species diversity. Recent climate change has alrea...
