American sugar beet farmers produce half of our domestic refined sugar valued at over $3 billion per year (APHIS, 2010). The U.S. District Court for the Northern District of California (CA District Court) will soon determine whether U.S. farmers can continue to grow genetically modified (GM) sugar beet (Beta vulgaris ssp vulgaris var altissima) in the case of Center for Food Safety v. Vilsack (...

for evaluation of efficiency and yield per surface unit with using the 56 sugar beet producer countries data in year 2005 an econometric model based on cols method has presented. with this model maximum sugar beet production efficiencies considering the harvested area and annual rainfall measure and level of mechanization has been determined. in total iran with production efficiency 0.43 is in ...

The global cultivation area of genetically modified plants (GMPs) includ ing soybean, maize, cotton, canola (oilseed rape) and sugar beet has been increasing consistently since they were first cultivated commercially in 1996, reaching 160 million hectares (ha) in 2011 [1]. By 2011, the global area of planted insectresistant crops was 66 million ha. The rapid adoption of insect-resistant crops i...

background and objectives: the most important determining factor in sugar beet root yield is seed quality. seeds with germination percentage are lower; the germination is slow and non-uniform, will produce plants that initial growth is slow. according to various studies indicate that harvest time is an important factor influencing the quality of sugar beet seed. in the early harvest of sugar be...

saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...

Ethanol obtained from biomass has potential to become an important sustainable transportation fuel in the near future. Renewable energy sources, such as lignocellulosic biomass, are environmentally friendly because they emit less pollution without contributing net carbon dioxide to the atmosphere. Among kinds of biomass, lignocellulosic biomass is a very useful feedstock to economically produce...

An interesting application of agricultural renewable sources is the employment of ethanol for supplying Molten Carbonate Fuel Cells (MCFCs). For that purpose, ethanol has to be converted into hydrogen by a steam reforming process. MCFCs are particularly suitable for this kind of applications due to their high tolerability to the impurities which are contained into the reaction products and also...

Sugarcane (Saccharum spp.), a plant of the Poaceae family, is an important source of sucrose and ethanol in many tropical and sub-tropical countries. It was introduced in Brazil during the colonization period, and today represents one of the main cultures of the economy. Brazil is currently the world’s largest sugarcane producer. The 08/09 crop yielded approximately 569 millions of tons, totali...

This study investigated the development of the microbial community during a long-term (337 days) anaerobic digestion of maize and sugar beet silage, two feedstocks that significantly differ in their chemical composition. For the characterization of the microbial dynamics, the community profiling method terminal restriction fragment length polymorphism (TRFLP) in combination with a cloning-seque...
