| Summary: | The objective of this research was to determine the effects of organic fertilizers on nutrient contents in leaves and corms of hybrid Gladiolus sp. used as a cut flower in landscape arrangement. This study was conducted in a randomized experimental design with three replications. Chicken manure, farmyard manure, peat and waste mushroom compost were used as organic fertilizers. As a result, while the highest mean contents of nitrogen (1.97%), iron (160 ppm) and manganese (128 ppm) in leaves were obtained in chicken manure application, the highest mean contents of potassium (2.01%), calcium (1.80%) and magnesium (0.25 ppm) were determined in waste mushroom compost application. The highest mean contents of phosphorus (0.30%), zinc (25.3 ppm) and copper (9.29 ppm) in leaves were found with peat, control and farmyard manure applications, respectively. The highest mean contents of phosphorus (0.83%), potassium (1.47%), calcium (0.57%), manganese (73 ppm) and zinc (67.3 ppm) in corms were obtained in farmyard manure applications. While the highest mean contents of nitrogen (4.86%) and copper (20.9 ppm) in corms were determined in chicken manure application, the highest mean contents of iron (17.6 ppm) and magnesium (0.20 %) in corms were obtained in peat and waste mushroom compost applications, respectively. Application of organic fertilizers increased macro and micro nutrient contents in leaves and corms of hybrid Gladiolus sp.
