This research was done to determine the effect of increasing Humic acid application on some nutrient element contents of cress (Lepidium sativum L.) plant. For this purpose according to randomize block experimental design, an experiment was done with three replications in greenhouse conditions. Cress plant seed was sowed 1.5 g/ m2. Four humic acid doses (I. dose: 0 mL /m2, II. dose: 8 mL /m2, III. dose: 16 mL /m2 and IV. dose: 24 mL /m2) were applied to cress plant. Then cress plants were harvested 30 days after planting. Dry matter yield and some nutrient (N, P, K, Ca, Mg, S, Fe, Cu, Zn and Mn) contents of plants were determined. According to the results, important increases some nutrient element contents of plants were determined with increasing humic acid applications. These increases were found 1. dose 5.52%, and 4. dose 6.04%, for N element, respectively. Other macro elements P (0.70%, and 0. 82%); K (6.85%, and 7.67%); Ca (1.72%, and 2.01%); Mg (0.13% and 0.15%) and S (1.04%, and 1.17%), respectively. Some micro element (Fe, Cu, Zn and Mn) contents of cress plant, 1. dose: 89.86, 9.59, 59.50 and 56.20; 4. dose: 102.17, 11.03, 67.67 and 76.63 mgkg-1, respectively. These increases were found statistically significant at the level of 5% for each nutrient element, except Mg.
