On the basis of literature and own experiments some more important economic and organizational aspects of maize cultivation for grain, silage and CCM were presented. It was ascertained that the criteria for that plant evaluation have to be extensive, and in this connection a term „economic value” was used here. The estimation was done in relation to so-colled standard technology developed by IUNG, most often used in Polish agriculture. The maize cultivation, expecially for grain, requires high outlays. The costs and effects of maize cultivation were compared to the other market plants such as spring barley and spring wheat.
