Abstract: Since rice is one of the most important strategic plants for the country’s economy and the people of the north of Iran regions. On the other hand, the problem of soil salinity in some paddy fields there is in the Caspian Sea region due to being located in areas with the saline water table at a very low depth. Therefore, it is necessary to study the possibility of rice production in the presence of shallow water table and saline; because soil salinity in the coastal areas of Mazandaran province in the north of Iran is a big problem that threatens the cultivation of rice in this region. Research was conducted in 2018 using large lysimeter at the Climate Research Center of Agricultural and Natural Resources College of the University of Tehran. The present study was performed in an insulated metal lysimeter under two main treatments with non-saline water (NSW) and high saline water (HSW), both in the presence of a shallow water table. The irrigation water salinity was equal to 0.94 dS m-1 for both treatments, and the shallow water table salinity at a depth of 40 cm below the soil surface for HSW treatment was adjusted to 20 dS m-1 as artificial feeding. The results of comparing the average yield parameters showed that the shallow static surface salinity on leaf area index (LAI), root length (RL), plant height (PH), membrane stability index (MSI), chlorophyll (SPAD), relative water content (RWC) and biomass (BIO) parameters did not have a significant effect on the two treatments and caused a small difference between the yield parameters. The difference between the rice yield parameters of the control treatment and the salinity treatment was about 1 to 12 percent. Meanwhile, grain and biological yield in HSW treatment compared to NSW decreased by 3.2% and 4.5%, respectively. Also, the harvest index in the two treatments NSW and HSW was almost equal and was calculated to be 57.55% and 58.31%, respectively. Therefore, according to the result of this study, it can be find that there is exploring the possibility of cultivation and production of rice in the presence of shallow water table and saline.
