In this study it was aimed that effects of different doses of phosphorus and humic acid on micro nutrients contents of gladiolus cultivars. Rose Supreme, Deppest Red and Essential gladiolus cultivars were used in this experiment.Three different doses of phosphorus (P1:0, P2:100, P3:200 mg P kg-1) and humic acid (HA1:0, HA2:1000, HA3:2000 mg HA kg-1) were applied plastic pots having 3 kg plant growing media.The experiment was ended after 140 days following planted corm. Iron, Copper, Zinc and Manganese were analysed in the harvested plants.When taking into account micro nutrient contents significant differences were not found among cultivars except Cu contents.The differences of Cu contents caused by different cultivars were found significant at 5% level statistically.Effects of different phosphorus applications on Mn and Fe contents of gladiolus were determined significant at 1% level. Effects of cultivar x phosphorus interactions were found significant (1%) in Zn and Cu contents. Cultivar x phosphorus x humic acid interactions caused the significantly differences in Mn and Cu contents statistically.The highest Fe and Zn contents were obtained as 57.9 mg kg-1 and 82.0 mg kg-1 in HA3 applications. The highest Cu contents were found as 11.4 mg kg-1 in HA2 application.
