Abstract :The present research has been contented to determine the effects of the increased leonardite application on the some macro and micro nutrient elements of pak choi ( Brassica rapa L. subsp. var. Chinensis L.) plant. The research was designed as 3 replications according to the randomized block experimental design. Leonardite was applied to the parcels with 4 doses and as the 1 st dose: 0 ppm m -2 , the 2 nd dose: 60 ppm m -2 , the 3 rd dose: 120 ppm m -2 and the 4 th dose: 150 ppm m -2 . According to research results, the total N content of the plant samples were determined of 5.43 % , 5.58 % , 5.69 %, and 5.73 % for four leonardite doses respectively. The contents were determined as P ( 0. 40 % , 0. 42 % , 0. 41 % , 0. 41 % ); K (5.49 % , 5.73 % , 5.83 %, 6.01 % ); Ca (1.85 % , 1.91 % , 2.06 %, 2.29 % ); Mg ( 0. 12 % , 0. 13 % , 0. 13 % , 0. 14 % ); and S (3.39 % , 4.65 % , 4.83 %, 4. 84 % ) and some micro elements contents were obtained as Fe (96, 110, 112, 120 mgkg -1 ); Cu (5, 8, 18, 24 mgkg -1 ); Mn (12, 16, 22, 94 mgkg -1 ); and Zn (32, 34, 36, 37 mgkg -1 ) for four doses, respectively. According to the results, the effects of the increasing doses of the leonardite application on some macro and micro nutrient elements contents of pak choi plant were determined statistically significant. These increases were found to be significant at the level of 5 % statistical degree, except P and Mg nutrient elements.Keywords : Leonardite, nutrient element, Brassica rapa L. subsp. var.
