Effect of different doses of slow-disintegrating fertilizer on the quality of impatiens' seedlings (Impatiens walleriana L.)

Abstract

The paper studies the effect of applying different doses of slow disintegrating fertilizer 'Scotts' ( Osmocote Exact ) of the formulation 15:9:9:MgO + Me to the quality of impatiens seedlings. The impatiens' seedlings were produced in poly-styrene containers ( speedling system ) and poly-propylene pots ( pot system ). During the seedlings' production, the fertilizer was added in different doses (0, 1, 2, 3, and 4g/l ). The obtained results have shown that the dose of 4 g/l of fertilizer significantly influences on the qualitative features of the impatiens' seedlings.

U radu je ispitivan uticaj različitih doza spororazlagajućeg đubriva Scotts (Osmocote Exact) formulacije 15:9:9:MgO + Me na kvalitet rasada impatiensa. Rasad impatiensa 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 4g/l ). Dobijeni rezultati ukazuju da doza đubriva od 4g/l supstrata značajno utiče na kvalitativne osobine rasada impatiensa jove.
