Abstract

Because of world population growth and limited water resources, irrigation should be moved in direction of producing more yield with less water. Therefore researches has concentrated on improvement of water and nitrogen use efficiency, which numerical simulation is the effective solutions to optimize the management of water and fertilizer in the field in order to achieve the maximal yield and minimal NITRATE POLLUTION of soil in water deficiency crisis condition.This shows the necessity of evaluating of new user friendly models to identify the correct distribution of water and solute in the soil and choosing the best management.The Eu-Rotate-N model has been developed for simulation and optimization of nitrogen use in vegetables rotation and without the need to calibration.This study in 2015 was conducted to evaluate the efficiency of Eu-Rate-N model in simulation of moisture and nitrogen distribution and yield under drip and surface irrigation system and for pepper plant in a farm with silty clay loam soil in Isfahan. Four statistical index, RMSE, NRMSE, r2, d in order to model validation was calculated. These indexes for soil water content in both treatments and in the complete soil profile were 0.025, 13.26, 0.65, 0.996 respectively. Also NRMSE for soil nitrate content and plant yield in both treatment was less than 20 percent and r2 was more than 90 percent which pointed out to well efficiency and well process of simulation of the model.So the Eu-Rotate-N model efficiency for simulating soil water and nitrate contentdistribution and yield for pepper was confirmed and we can use Eu-Rotate-N model for the simulation and optimization of agricultural water management in the HOT AND DRY CLIMATE conditions in heavy soil texture for pepper.
