Application of 30g nitrogen plant significantly increased the number and diameter of bottom breaks (BB), first (L1) and second (L2) order laterals and plant spread, while24g potassiumsupply significantly increased only the number and diameter of L1, L2 and plant spread (N/S). The multiplex supply (12g/plant) also significantly increased only the number of L1 and L2 and plant spread. The plants receiving 30g N + 24g K recorded significantly improved performance in terms of number and fresh weight of flowers, stem and bud length, bud diameter and also production of good quality flowers (30g N:45.87%; Og N: 24.29% and 24g K: 38.50%; Og K: 31.68% quality flowers), while Multiplex application (12g/plant) significantly improved only flower number and bud diameter. The soil and leaf N, K, Zn and Cu were significantly increased, respectively by the application of N, K and Multiplex, except K application, which did not influence the leaf K content.
