  The objective of this study was the ethanol which classified as agro fuels. The aim of our research was the calculation of efficiency of bioethanol production, and evaluates the yield of maize hybrids grown for this purpose. We examined the energy demand of corn production per hectare in two vintages of 2009 and 2010. The focus of the experiment was placed in three different doze of fertilizer. Results show that the control corn plot used the least amount of non-renewable energy. Improving starch yield by adding fertilizer required additional nonrenewable energy inputs. So then the invested energy has a great impact on the efficiency.

  The objective of this study was to evaluate the effects of crop year on the main components of maize grown for bio-ethanol production yield, starch content and starch yield per hectare of maize hybrids were investigated in a droughty (2007) and in a favourable years with optimal weather conditions (2008, 2009). We measured very low starch yield (1.5 t ha^-1) in the year with unfavourable precipitation supply (2007) together with higher starch content (73%). In the case of good precipitation supply we measured a much higher starch yield per hectare (7.7 t ha^-1) with lower content (72.4%). In 2009 the starch content (74.5%) exceed the results of the two previous years, but on the other hand the average of starch yield was (4.9 t ha^-1) which falls between the other two years values.
