While studying the impact of soil, climatic and weather factors on the crop yield, we have defined some criteria. They afford background for the selection of ecologically uniform territories and their differentiated use by separate crops. Taking into consideration the ecological potential defined and the possibilities of the use of separate agroecosystems (species, varieties and hybrids) Dnipropetrovsk region territory is divided into three agricultural zones with the subdivision into six agricultural subzones. The relationships between ecological parameters and crops yield have been established. The yield data on strain testing stations and collective and private farms were analyzed as well. All this also was the basis for the construction of a mathematical model. The math modeling method was used to define the quantitative dependence of the yield upon agro-and-climatic conditions.
