In order to study on the effect of Iron and Manganese on quality and quantity characteristics, 2 years Field experiment was conducted with 12 treatments and 3 replications at factorial in the basic of complete randomized block design. 4 levels of Iron (0, 15, 30 and 45 kg.ha-1 Iron from Iron sulfate) and 3 levels of Manganese (0, 10, 20 kg.ha-1 Manganese from Manganese sulfate) as first and 2nd. factors, respectively. Results, showed that the effect of Iron on flower height, panicle length, stem diameter, floret length, floret number, flower wet and dry weight, corm number, corm wet and dry weight, vase life, open floret percentage, iron and manganese concentration of shoot, iron and manganese concentration of root (corm) were significant. The effect of Manganese on flower height, panicle length, stem diameter, floret length, floret number, flower wet and dry weight, corm number, corm wet and dry weight, vase life, open floret percentage, iron and manganese concentration of shoot, iron and manganese concentration of root (corm) were significant. Data showed that the interaction of Manganese and Iron on flower wet and dry weight, corm wet and dry weight, vase life, open floret percentage, iron and manganese concentration of shoot, iron and manganese concentration of root (corm) were significant. With regard to results of experiment, Fe30Mn20 treatment is the best treatment as flower height, floret diameter, flower wet and dry weight and vase life and produced best quality and quantity characteristics among of other treatments. Key words: Tuberose, Iron, Manganese, Growth characteristic, Iron and Manganese in shoot, Iron and Manganese in root (Corm).
