Effect of applying different rates of slow - disintegrating fertilizer on the quality of marigold (Tagetes patula L.) and scarlet sage seedlings (Salvia splendens L.)

Abstract

The paper investigates the effect of applying different rate of slow disintegrating fertilizer Scotts (Osmocot Exact) with the formula 15:9:9:MgO+Me to the quality of seedlings of marigold and scarlet sage. The marigold and scarlet sage seedlings were grown in poly-propylene containers (speedling system) and poly-propylene pots (pot system). Slow disintegrating fertilizer rate have been applied to the seedlings in the course of their growing (0, 1, 2, 3, i 4 g/l). The obtained data show that the 4g/l substrate rate of slow disintegrating fertilizer has significant effects on the studied parameters of seedlings quality of studied species.
