Influence of Physical and Chemical Properties of Growing Media on the Quality of French Marigold (Tagetes patula L.) and Carrot (Daucus carota L.)

Marigold (Tagetes spp.) is present in every garden because it is not a demanding plant. Carrot (Daucus carota L.) is one of the ten most important garden vegetables which prefers acid to neutral soils and airy one. The aim of this research was to determine differences in growth and development of French Marigold in two growing media (soil type Eugley and substrate) and to determine quality properties of carrot growth in two different soils (Luvisol and Eugley). The research was randomized, in 4 repetitions for both cultivars. Properties determined for French Marigold were: height, number of branches, number of leaves, and mass of fresh transplant, further more dynamic of growth have been monitored as well as development of flowers due to counting number of rosebuds, number of flowers and their diameter and in the end of research following parameters were measured: height, number of branches, diameter of stalk, mass of the above the ground part of the plant and mass of dry matter of the above of the ground part of plant. Regarding carrot following parameters were measured: diameter of the root, mass of the root, mass of the leaves, number and lenght of the leaves. The collected data have been statistically analyzed by variance analyzes (F test) and differences between treatments have been determined with LSD-test. Significantly higher values (P≤0.01) have been determined for French Marigold growth in substrate regarding those growth in soil and significantly higher values (P≤0.01) for carrots growth in Luvisol soil type.
