Effect of organic fertilizers and location on herb yield of Pannonian thyme (Thymus pannonicus all. Lamiaceae)

Abstract

Population of Pannonian thyme originating from the Vršački Breg, grown and produced at the Institute of Medicinal Plant Research 'Dr Josif Pančić' from Belgrade was tested in this study. The trial was set up in 2012 as a completely randomized block design with four replications in Pančevo, Bavanište and Gorobilje. The following organic fertilizerwere applied: Italpollina, Dcm Ecomix I and Dcm Ecomix IV in two doses: 1000 kg ha-1 and 2000 kg ha-1 and the control variant without fertilization. The aim of this study was to determine the effect of location and use of organic fertilizers of different composition on thyme herb yield. Pannonian thyme herb yield varied greatly depending on the location, various fertilizers and the interaction of these two factors. Bavanište showed was significantly higher yields of Pannonian thyme herb compared to Gorobilje and Pančevo. The highest yield was obtained in the herb V6 fertilization variants (DCM Ecomix IV (7-7-10) 2000 kg ha-1) and lowest in the V7 variant (control without fertilization).

Testirana je populacija panonskog timijana koja potiče sa Vršačkog Brega, koja se gaji i umnožava u Institutu za proučavanje lekovitog bilja 'Dr Josif Pančić' iz Beograda. Ogled je postavljen 2012. godine po metodu potpuno slučajnog blok sistema u četiri ponavljanja u Pančevu, Bavaništu i Gorobilju. Primenjena su organska đubriva: Italpollina, Dcm Ecomix I i Dcm Ecomix IV u dve doze - 1000 kg ha-1 i 2000 kg ha-1 i kontrolna varijanta bez đubrenja. Cilj istraživanja bio je da se utvrdi uticaj lokacije i primene organskih đubriva različitog sastava na prinos herbe panonskog timijana. Prinos herbe je veoma značajno varirao u zavisnosti od ispiti- vane lokacije, varijante đubrenja i interakcije ova dva faktora. U Bavaništu je ostvaren značajno veći prinos herbe panonskog timijana u odnosu na Gorobilje i Pančevo. Najveći prinos herbe dobijen je u V6 varijanti đubrenja (Dcm Ecomix IV (7-7-10) 2000 kg ha-1), a najmanji u V7 vari- janti (kontrola bez đubrenja).
