Transplanting reduces the risk of frost and shortens the time of plant production in the field, and it is possible to do two turns of cultivation. Research and investigation in the field of determining the water productivity, especially in transplantation crops, which are introduced as a solution to increase productivity in dry areas, is of particular importance. for this purpose, experiments in the form of split plots in the form of The design of randomized complete blocks was implemented in four replications in two turns of spring and summer cultivation on transplantation and direct (seed) corn. In this experiment, the main plots included three levels of irrigation water supply (75, 100, and 125% of the full water requirement) and the subplots included: transplantation and direct cultivation of corn. The results showed that in spring cultivation, the yield and water productivity in the transplantation cultivation treatment was higher than the direct cultivation treatment, but in summer cultivation, no significant difference was observed between the yield and water productivity in the transplantation and direct cultivation. Both in spring and summer cultivation, the yield difference in the treatments of 100 and 125% of water supply was not significant, but it was significant with the treatment of 75%. Therefore, the best yield of corn is obtained under the influence of irrigation level treatment in providing 100% of the water requirement. In general, it can be recommended that if the main goal in growing corn is to increase yield and water consumption efficiency, this goal can be achieved by spring corn cultivation, but in summer cultivation, the yield and water consumption efficiency does not increase.
