Comparative analysis of maize hybrides grown for bioethanol production purposes
How to Cite
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.
