Abstract
The purpose. To estimate the potential productivity of agricultural lands was based on different scenarios simulation of water and land use on a pilot area of Kherson district for reasoning restoration of irrigation on-site. Methods. Analytical, statistical, immitation (simulation), method of system analysis. Results. As a result of typization of pilot area it was allocated typological zones with similar soil and climatic conditions. Simulation of potential land productivity on each typological zones were done by dynamic model of production process WOFOST on example of maize. The assessment of land productivity was done on the basis of the simulation results of water and land use scenarios with different natural and farming conditions. Conclusions. The simulation method of water and land use scenarios is allowed to consider different influence on the formation of potential land productivity under different natural and economic conditions, and to select economically profitable and environmentally safe option of restoration of irrigation.

Key words: territory typization, simulation, potential maize yield, land productivity, water and land use scenarios.
