Proper and efficient use of water in the agricultural sector is of great importance. Therefore, it is not possible to achieve development without preventing water loss and utilizing new technologies. One way to achieve this aim is to replace the tape irrigation system Instead furrow irrigation method. For this purpose, two irrigation methods and water requirement for peanut yield and water use productivity in a split plot experiment were conducted in a completely randomized block design with three replications in 2015 in Guilan province. The main treatment consisted of two levels of surface irrigation (furrow) and tape and sub-treatment consisted of 40, 60, 80 and 100% water requirement management. The results showed that the highest biological yield, pod and seed yield under tape irrigation and 100% water requirement were 13894, 5029 and 3273 kg / ha, respectively. The highest water use productivity based on biological yield was observed in diameter irrigation conditions at 100 and 75% of water requirement with average of 2.12 kg / m3. The highest water use productivity was based on pod and seed yield under tape irrigation and 100% water requirement with mean of 0.77 and 0.5 kg / m3, respectively. Due to the peanut water requirement and the limited rainfall and water resources at anthesis time, the least water should be used to the maximum. Therefore, tape irrigation can be used as an efficient and useful tool for optimizing peanut moisture.
