Effect of natural biostimulators and slow-disintegrating fertilizers on the quality of sage nursery stock under different growing conditions

Abstract

The effect of natural biostimulators and slow-disintegrating fertilizers on the quality of sage nursery stock was analyzed with the aim of intensifying the production of medicinal, aromatic plants and spice herbs. Nursery plants were grown in polystyrene pots and the mode of growing was either non-pruned or pruned. During the growth of the nursery seedlings natural biostimulators were applied at the substrate rates 1-3 g/l. Based on the results obtained it can be concluded that the application of both natural biostimulators and slow-disintegrating fertilizers can affect the quality of sage nursery stock.

U cilju intenziviranja proizvodnje rasada lekovitog, aromatičnog i začinskog bilja ispitivan je uticaj primene prirodnih biostimulatora i spororazlagajućih đubriva na kvalitet rasada žalfije. Rasad je proizveden u polipropilenskim saksijama. Primenjena su dva načina proizvodnje rasada u saksijama: bez orezivanja i sa orezivanjem biljaka. Prilikom proizvodnje rasada dodavani su različiti prirodni biostimulatori Megafol (folijarno) i Viva (zemljišno) i spororazlagajuće đubrivo Scotts (Osmocote Exact) u različitim dozama. Dobijeni rezultati ukazuju da primenom prirodnih biostimulatora i spororazlagajućeg đubriva značajno utičemo na kvalitet rasada žalfije.
