Sažetak
In spite of producers preferences for conventional horticulture, newer research results pointed out possibilities of growing vegetables in alternative ways, which are environment friendly, but still obtain satisfactory economic results. The goal of this research was to determine influences of alternative crop management systems (organic and integrated) and measure effects of endomycorrhiza on vegetative growth and leek yield. During 2003 and 2004 a two-factor trial with three repetitions and split-plot field research design was set up in Otočac (Croatia). The main factor “ crop management” had three levels (organic, integrated and conventional) while the sub factor “ mycorrhiza” had two levels (leek seedlings inoculated with endomicorrhizal fungus Glomus mossae and non-inoculated seedlings). On plots assigned for organic crop management, common vetch plants (Vicia sativa L.) were grown on plots, then mowed down and used as mulch. Other plots were mulched with black polyethylene film. Leek seedlings were planted with root ball ; fertilization and cultivation measures were performed according to basic principles of organic, integrated and conventional crop management system. In 2004, field results showed lowest densities of plants in integrated production management - 9, 76 plant/m2 (planned 10, 67 plant/m2) and was statistically significant. Plants in organic production had longer blanched stem in the same year (for 36 or 44%) in comparison with integrated and conventional crop management system. In both years, plants cultivated in integrated and conventional systems achieved 17 to 34% larger diameters of blanched stem than plants in organic management. Likewise in both years plants weight in integrated and conventional production were between 45 and 70% higher then in organic production system. Consecutive, in both years the marketability for integrated and conventional production was higher relating to organic production - between 60 and 71%. No significant interaction of crop management and endomycorrhiza was indicated in the morphological features and leek yield.
