Meloidogyne species pose a significant threat to crop production in Africa due to the losses they cause on a wide range of agricultural crops. The direct and indirect damage caused by various Meloidogyne species results in delayed maturity, toppling, reduced yields and quality of crop produce, high costs of production and therefore loss of income. In addition, emergence of resistance-breaking M...

During the last two decades, the public and private sectors have made substantial research progress internationally toward improving the nutritional value of a wide range of food and feed crops. Nevertheless, significant numbers of people still suffer from the effects of undernutrition. As newly developed crops with nutritionally improved traits come closer to being available to producers and c...

Two experiments were conducted, first was to estimate maize seedling damage in farmers’ fields and a simulation experiment. This study aim investigate the impact of rodent pest species, crop semi-arid areas at pre-harvest, with view provide farmers appropriate information on management interventions. In fields, assessment done by counting number damaged or removed seedlings each planting ...

Alfalfa losses and quality changes begin as soon as the mower contacts the standing crop and these losses continue until the preserved feed is consumed. Harvest losses are caused by plant respiration, rain, and mechanical damage by equipment. Loss from plant respiration is relatively small when the crop is dried quickly under good drying conditions, but under slow drying conditions it can be up...

stuart smyth and Peter Phillips, both from the University of saskatchewan, review the consequences of an increasingly divergent regulation structure in the biotechnology sector. Regulatory decisions for genetically modified (gM) crops in north america and numerous countries in Latin and south america, australia, and asia are, in the views of the authors, predictable and efficient. in stark cont...

This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included ...

One of the least understood areas in the environmental risk assessment of genetically modified crops is their impact on soil and plant-associated microbial communities. In a review of literature, Dunfield and Germida (2004) found that transgenic plants and plant litter can influence the composition of the plant-associated microbial communities. Their review also points to such effects having be...
