This study was carried out in Diyarbakır ecological conditions for two years in 2021 and 2022. The effects of Rhizobium japonicum bacteria (150 ml da^-1) and different 5 kg da^-1, 10 kg da^-1, 15 kg da^-1, 20 kg da^-1 and 25 kg da^-1 nitrogen doses on plant height (cm), number of fruits perplant, number of ginefor perplant, seed yield (g), oil (%) and protein content (%) in some Halisbey and Sultan peanut varieties werein vestigated. In the experiment, which was carried out with 3 replications according to the experimental design of divided parcels in random blocks, varieties constitute the main parcel and fertilizer applications constitute the sup-parcels. According to the results; Interms of plant fruit number, plant stem weight, plantseed weight, oiland protein ratio, year, fertilizer, year x fertilizer, variety, variety x fertilizer and year x variety x fertilizer interaction were significant. The highest number of fruit splant, plantstem weight (g), plantseed weight (g) and oil ratiovalues ​​were obtained from 5 kg da^-1 nitrogen dose application. Protein ratio (%) was found to be higher than the control in bacteria application and all nitrogen doses. For plant seed weight, which is an important yield element, 5 kg da^-1 (350.82 g) was determined as the best dose in fertilizer doses.
