Sažetak
U ogledu sa dve domaće sorte belog sleza, izvedenom u Mošorinu, ispitivan je efekat različitih doza azotnog đubriva, veličine vegetacionog prostora i načina razmnožavanja na prinos suvog korena sleza. Najveći prinos suvog korena (4.264 kg ha-1) postignut je na varijanti bez azota, što je bilo za očekivati obzirom da je ogled postavljen na baštenskom zemljištu obilno đubrenom stajnjakom. Najveći prinos dobijen je pri najmanjem razmaku između biljaka u redu (20 cm). Ispitivanjem načina razmnožavanja ustanovljeno je da je pri direktnoj setvi iz semena prinos korena bio za 1.664 kg ha-1 veći nego pri rasađivanju.
Abstract
In experiment with two domestic marshmallow varieties, carried out in Mošorin the effects of different N-fertilizers (control, 50, 80, 120 kg ha-1), 4 growing area (50 cm inter-row spacing x 20, 30, 40, 50 cm inside spacing) and 2 planting methods (direct sowing and plant transplantations), were tested. The obtained results show that the highest dry root yield (4.264 kg ha-1) was achieved without use of nitrogen, which was expected since the trial was abundantly fertilized. The highest yield was obtained in lowest spacing applied between the plants (20 cm). The analysis of reproduction method showed that using the direct sowing method the yield was 1.664 kg ha-1 higher than using the plant transplantation.
