The influence of slow disintegrating fertilizers’ on quality on flower seedlings

Abstract

The work has examined the influence of slow disintegrating fertilizer dosages of Scotts (Osmocote Exact) formulation 15:9:9:MgO + Me on quality of flower seedlings: French marigold (Tagetes patula L.), Scarlet sage (Salvia splendens L.), gazania ( Gazania rigens L) and impatiens (Impatiens wallerana L.). seedlings. The researches were done during 2006 and 2007 in glasshouse of Belgrade’s Faculty of agriculture. The seedlings on flower are produced in polystyrene containers (speedling system) and polypropylene pots (pot system). During the production of seedlings the fertilizer has been applied in dosages (0, 1, 2, 3, i 4 g/l). The results show that the fertilizer’s dosage of 4g/l of substrata influences on qualitative properties on flower seedlings.

U radu je ispitivan uticaj različitih doza spororazlagajućeg đubriva Scotts (Osmocote Exact) formulacije 15:9:9:MgO + Me na kvalitet rasada kadifice (Tagetes patula L), ukrasne žalfije (Salvia officinalis L.), gazanije (Gazania rigens L.) i lepog jove (Impatiens wallerana L), Ogled je postavljen u stakleniku Poljoprivrednog fakulteta u Beogradu tokom 2006 i 2007 godine. Rasad cveća je proizveden u polistirenskim kontejnerima (speedling system) i polipropilenskim saksijama (pot system). U toku proizvodnje rasada dodavano je đubrivo u dozama (0, 1, 2, 3, i 4 g/l). Dobijeni rezultati ukazuju da doza đubriva od 4g/l supstrata značajno utiče na kvalitativne osobine rasada ispitivanih vrsta cveća.
