Knowing the appropriate cultivars and proper irrigation management is one of the most important factors affecting the growth and yield of peanut plant. The present study was conducted as split split plots in the form of a randomized complete block design with three replications, in 2018 and 2019 in Guilan Province. The main plot consisted of two methods of drip and furrow irrigation, and the sub-plots included supplying 125%, 100%, 75%, 50%, and 25% of water requirement, and the sub-sub-plot included two peanut cultivars Guil and Jonobi. The results of the study showed significant effect of irrigation method on seed yield (at p<0.5) and the effect of water supply on all measured traits (at p<0.1). The highest seed yield in 2018 and 2019 was observed in Guil cultivar with 100% water requirement of the plant with an average of 3221 and 3161 kg.ha-1, respectively. In the two study years, annual averages of seed yields in drip irrigation (1808 and 1803 kg/ha) compared to the furrow method (1753 and 1754 kg/ha) showed an increase of 3.1% and 2.8%, respectively. The correlation between traits, showed a positive and significant effect between seed yield and number of pods per plant, number of seeds per plant, and 100-seed weight. Based on the results, for peanut cultivation in the study area, Guil cultivar with drip irrigation and providing 100% of water requirement (5481 m3 of water/ha in this research) is recommended.
