What do we know about maize?
(Dr. Bódis László)

Maize keeps on being in the focus of interest
(Dr. Márton Jolánkai)

Maize market summary – Records are falling down again
(Edina Varga, Norbert Potori)
Although global maize production is rapidly growing, it cannot keep up with the demand. In Hungary over 8 million tons of maize were harvested in 2011, however, we are only number 4 in the rank of the EU member states with this data. Practically it may be taken for granted that a relatively significant part of the excessive product volume will be taken up by the Hungarian bio-ethanol industry.
