This study was conducted in 2018-2019 to determine the effects of leonardite applications on the yield and some yield components ofchickpeas in the ecological conditions of Siirt province. The trials were set up with 3 replications according to the randomized blockstrial design. Azkan variety was used as chickpea seed in the experiments. Leonardite doses were applied as 0, 25, 50, 75, 100 and 125kg da-1 . In the research, the effects of the applications on the plant height, first pod height, number of pods per plant, number of seedsper plant, 100-grain weight and grain yield were found to be statistically significant. According to the results of the research, plantheight, first pod height, number of pods per plant, number of seeds per plant, 100-grain weight and grain yield varied between 51,0- 57,5 cm, 27,9-33,1 cm, 30,2-34,2 adet $bitki^{-1}$ , 33,2-37,9 adet $bitki^{-1}$ , 31,2-35,4 g and 169,7-208,2 kg $da^{-1}$ . In terms of all the propertiesexamined, 100 kg $da^{-1}$ leonardite application in both years of the study gave the highest values. According to the results obtained fromthis study, it is recommended to use 100 kg $da^{-1}$ leonardite in chickpea cultivation in Siirt province ecological conditions.
