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.application/pdfbioethanolmaize hybridstarch contentfolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/46/2399Acta Agraria Debreceniensis46Acta agrar.
