Based on data of 3-year field experiment with maize (H 708 hybrid) on two soil varieties and different irrigation levels the economocally optimal nitrogen fertilizer rate and plant density have been estimated. The production and economic risks, depending on plant density, irrigation and nitrogen fertilizer rate have been analyzed. On the basis of these assessments it has made attempt to specify the technology of corn cultivation.
