The effect of natural biostimulators and slow-disintegrating fertilizers on the quality of rosemary seedlings (Rosmarinus officinalis L.)

Abstract

In the present work the effect of natural biostimulators and different doses of slow disintegrating fertilizer on the quality of rosemary seedlings was studied. Rosemary seedlings were produced in containers, according to the 'speedling system'. During the production of seedlings natural biostimulators Megafol and Viva and microbiological fertilizer Slavol were added. The applied biostimulators made a significant effect on the quality of rosemary seedlings. Different doses of the slow disintegrating fertilizer Scotts (Osmocote Extact) were applied (0, 1, 2, 3 and 4 g/l), which also produced a significant influence.U radu je ispitivan uticaj prirodnih biostimulatora i razlicitih doza spororazlagajuceg djubriva na kvalitet rasada ruzmarina. Rasad ruzmarina je proizveden u kontejnerima po 'speedling sistemu'. Tokom proizvodnje rasada dodavani su prirodni biostimulatori Megafol i Viva i mikrobiolosko djubrivo Slavol. Upotrebljeni biostimulatori su ostvarili znacajan efekat na kvalitet rasada ruzmarina. Koriscene su i razlicite doze spororazlagajuceg djubriva (0, 1, 2, 3 i 4 g/l) Scotts (Osmocote Extact), koje su takodjer ostvarile znacajan uticaj.
