MINIMIZATION OF WATER NEEDS IN IRAQI AGRICULTURE IN LIGHT OF THE PREVAILING CROPPING COMBINATION DURING

The research aims to study the optimal allocation of irrigation water that is used irrigate various agricultural crops at level Iraq. In order achieve goal research, two economic models were formulated according linear programming technique. first model aimed minimize needs prevailing crop combination during average period (2017-2020), while second maximize total profit margin unit for minimizes same period. was estimated with proposed plans. plan included non-imposing legislative restrictions related certain areas basic bias food security requirements population, as well recently banned from import by Iraqi government, imposition and addition did not appear in table solution plan. Results indicated there a surplus resource plans models, its quantity amounted about 363.361, 9.178 million m3 each plan, respectively, compared amount needed current cropping combination, which 4.736726 billion mentioned analysis also showed preference results result expansion cultivation most important vegetables local consumption.
