Abstract
This research was done to determine the effect of increasing Humic acid application onsome nutrient element contents of cress (Lepidium sativum L.) plant. For this purposeaccording to randomize block experimental design, an experiment was done with threereplications in greenhouse conditions. Cress plant seed was sowed 1.5 g/ m2. Four humicacid doses (I. dose: 0 mL /m2, II. dose: 8 mL /m2, III. dose: 16 mL /m2 and IV. dose: 24mL /m2) were applied to cress plant. Then cress plants were harvested 30 days afterplanting. 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 somenutrient element contents of plants were determined with increasing humic acidapplications. These increases were found 1. dose 5.52%, and 4. dose 6.04%, for Nelement, respectively. Other macro elements P (0.70%, and 0. 82%); K (6.85%, and7.67%); 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% foreach nutrient element, except Mg.
