The influence of substrates on growth and development of tagetes (Tagetes officinalis L.)

Kadife su ukrasne vrste čiji je uzgoj široko rasprostranjen jer nisu zahtjevne za uzgoj. One dobro podnose visoke temperature, a toleriraju i različita tla. Cilj rada bio je utvrditi razlike u razvoju kadife (Tagetes officnalis L.) uzgajane u proizvedenim supstratima i tlu. U pokusu su korišteni supstrati za uzgoj presadnica (Potgrond H) i cvijeća (Florabella) i tlo. U kontejnere sa 104 sjetvena mjesta, napunjene susptratom Potgrond H i tlom, posijano je sjeme kadife. Nakon što su razvile 4 lista, po 50 biljaka presađeno je u lončiće br. 10 u različitim kombinacijama (tlo-tlo, tlo-supstrat, supstrat-tlo i supstrat-supstrat). Na razvijenim biljkama mjerene su sljedeće vrijednosti: broj listova, broj pupova i cvjetova, promjer cvijeta, visina nadzemnog dijela, broj postranih grana, te masa nadzemnog dijela biljaka. Biljke uzgajane u sustavu supstrat-supstrat imale su se najveće vrijednosti, dok one u tlo-tlo najmanje.Tagetes are ornamental species whose cultivation is widespread because they are not demanding to grow. They can endure high temperatures and can tolerate different kinds of soil. The aim of the research was to establish differences in development of Tagetes grown in soil and substrates. In the experiment two types of substrate were used, one for growing flowers (Florabella), for growing seedlings (Potgrand H) and soil. The seeds were sown in containers with 104 seedbeds filled with substrate (Potgrand H) and soil. After the development of 4 leaves, 50 plants were planted in pots number 10 for growing in diffirent combinations (soil-soil, soilsubstrate, substrate-soil and substrate-substrate). On the developed plants the following valves were measured: number of leaves, number of buds onda flowers, the diameter of flowers, plant height above the mass of the above-ground part of the plant. The plants that were grown in the combination of two substrates had the highest valuse and the ones grown in the combination of two different soils had the lowest values
