Effect of fertilization on cabbage yield characteristics

Cabbage is the most common leafy vegetable in Croatia, where due to its climatic diversity can be grown all year round. Cabbage is mainly grown in conventional system, which could result in environmental pollution and endangering consumer health. In order to avoid possible adverse consequences of excessive use of mineral fertilizers, different application of reduced and organic fertilizer are studied. The aim of this study was to determine the effect of different fertilization on growth and yield of cabbage in the summer-autumn cultivation. Seedlings of early cabbage cultivar Parel were planted in soil fertilized with mineral, mineral-organic and organic fertilizers. Field trial was established at randomized block design with four replications with 30 plants per treatment and at two locations Križevci (continental region) and Sinj (mediterannean hinterland). Plants planted in Sinj achieved greater height, rosettes and stem diameter than those in Križevci. Significantly higher plants were recorded in treatment with mineral fertilizer. Plants fertilized with organic fertilizer had a smaller rosettes and stems diameter than plants fertilized with mineral and mineral-organic fertilizer. Cabbage harvested in Sinj had greater heads height and width and a longer stem inside the heads. Cabbage on the location Sinj achieved significantly higher yield, head weight, head efficiency and the percentage of dry matter than cabbage in Krizevci, while applied fertilizers had no effect on the same characteristics. Type of fertilization had no significant effect on the parameters of the head and yield, while the choice of location selection was crucial for cabbage growing in the summer-autumn season.
