Compositional studies comparing transgenic crops with non-transgenic crops are almost universally required by governmental regulatory bodies to support the safety assessment of new transgenic crops. Here we discuss the assumptions that led to this requirement and lay out the theoretical and empirical evidence suggesting that such studies are no more necessary for evaluating the safety of transg...

The designation “new crop” may be applied to virtually any useful plant that in some respect is new. The following categories of newness (which are not all mutually exclusive) are economically important in discussing new crops: (1) gathering new wild crops from nature; (2) cultivating an undomesticated plant not previously grown; (3) domesticating (changing genetically) an undomesticated plant;...
Pulse crops are considered minor on a global scale despite their nutritional value for human consumption. Therefore, they are relatively less extensively studied in comparison with the major crops. The need to improve pulse crop production and quality will increase with the increasing global demand for food security and people's awareness of nutritious food. The improvement of pulse crops will ...
Perennial crops need far less energy to plant, require less fertilizer and pesticides, and show a lower negative environmental impact compared with annual crops like for example corn. This makes the cultivation of perennial crops as energy crops more sustainable than the use of annual crops. The conversion into biogas in anaerobic digestion plants shows however much lower specific methane yield...
This research aimed to determine the effects of different cover crops and application ofbio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated theeffect of fall–winter species (common vetch, field pea, winter oats, fodder kale) and a mixtureof vetch and field pea with oats used as cover crops, as such as dead organic mulch andtraditional variant, without cov...
EU citizen's point of view. Submitted to Acta Agric. Scand., sec. B] Genetically modified crops (GM 9 crops) have been widely adopted by American farmers. Mainly two traits: herbicide resistance and 10 insect resistance constitute the area with GM crops. The commercial success of these crops rests upon 11 benefits in farm management and more generally upon improved efficiency in production. Eur...
Suggestions that novel, non-food, dedicated biomass crops used to produce bioenergy may provide opportunities to diversify and reinstate biodiversity in intensively managed farmland have not yet been fully tested at the landscape scale. Using two of the largest, currently available landscape-scale biodiversity data sets from arable and biomass bioenergy crops, we take a taxonomic and functional...
∗ Corresponding author: WU Quan, senior engineer, CAAE, mobile phone:+8613621043045 Abstract: Grain production is of great importance to any country, especially to China. It is very important for local and central governments to get accurate main crops acreage information in time. One noticeable problem is that the estimated accuracy for crops acreage in a certain year is not high, so that Remo...
During the hardly six months of suitable climatic window in summer season, many vegetable crops such as cabbage, cauliflower and radish are grown extensively in Ladakh region of India. These crops contribute significantly to the requirement of military and paramilitary troops in addition to the civil population inhabiting the region. In addition to growing these vegetable crops outdoor, some of...
