Appropriateness of the peat of 'Gaj' for marjoram nursery production (Majorana hortensis Moench.)

Abstract

In medicinal, aromatic and seasoning herbs nursery production, the choice of the substrate has an important role. Serbia is rich in peats, which are the main component of substrates for nursery production. The goal of this work was to apply home peat of Gaj and to estimate its appropriateness as the substrate component in marjoram nursery production. Peat of Gaj has been enriched by adding manure in different volume ratio (10-50 vol%) and soluble mineral fertilizers formulations 20:20:20+me in different doses (1.3; 1.9; 2.5; 3.1 i 3.7 g/l). Eleven substrates were tested. Peat (100%) was the control variant. Control versions were pure peat (100%). The best marjoram nursery plant quality was obtained using substrates with the manure share of 30 vol%. Among different dosages of used water soluble fertilizers, the 1.3 g/l dose had the best effect on the quality of marjoram nursery production. The obtained examination results show considerable effect of the home raw material - peat of Gaj application on the marjoram nursery quality.

U proizvodnji rasada lekovitog, aromatičnog i začinskog bilja značajno mesto pripada izboru supstrata. Srbija je bogata tresetima koji predstavljaju glavnu komponentu supstrata za proizvodnju rasada. Cilj ovog rada je primena domaćeg treseta iz Gaja i ocena njegove pogodnosti kao komponente supstrata u proizvodnji rasada majorana. Treset je oplemenjen dodavanjem stajnjaka u različitim zapreminskim odnosima (10-50%) i vodorastvorljivog mineralnog đubriva formulacije 20:20:20+ME u različitim dozama (1,3; 1,9; 2,5; 3,1 i 3,7 g/l supstrata). Ispitano je ukupno 11 supstrata. Kontrolna varijanta bila je treset 'Gaj' 100%. Ispitivanja su pokazala da se najbolji kvalitet rasada majorana dobija proizvodnjom na supstratu koji se sastoji od treseta 'Gaj' i stajnjaka u odnosu 70%:30%. Od primenjenih doza vodorastvrljivog đubriva, doza od 1,3 g/l je ostvarila najbolji efekat na kvalitet rasada majorana. Dobijeni rezultati istraživanja pokazuju značajan efekat primene domaće sirovine - treseta iz Gaja na kvalitet rasada majorana.
