Sažetak
In most wine growing countries of the world organic viticulture is now becoming more and more important. Unfortunately, despite of the favorable ecological conditions, this is not the case in Croatia,. The main reasons for that are the lack of legal regulation and subsidies for organic production and insufficient knowledge and experience of the producers and customers. In order to contribute to the wider spreading of organic viticulture the project “Organic viticulture on the family farms” has been started in 1998. with the support of the Ministry of agriculture and forestry. The main objective of the project is to test suitability of organic production for each of the four viticulture climatic regions in Croatia, through the comparison with usually used production technology. Four farms have been chosen in each climatic region (Međimurje, Slavonija, Istra, Dalmacija) and the technology of production has been defined separately for organic and conventional production (plant, protection, soil preparation, cover cropping, nutrition…). The influence of each variant on the level of the diseases damages, yield, chemical composition of most and wine as well as sensorial properties of the wine has been observed. In this paper we are presenting the results of the first two years of the conversion to the organic viticulture. In such a short period of time the creation of the stable and harmonious organic system could not been obtained. That is why we cannot reach the final conclusions, but the first results show: - The major difference between organic and conventional production has been observed in the efficiency of the used plant protection products. In the 1998, due to the very humid condition, the higher level of damages has been observed in organic variant. As we have expected, the problem has been much more distinct in the continental region especially in the zone B (Međimurje). In the 1999, which was extremely dry year, there was no significant difference in any climatic region considering diseases damages, which means that the product permitted for organic production were efficient enough for such a level of infection. - The higher yield obtained in conventional variant of some family farms were consequence of the losses in organic variant caused by the fungal diseases. - There was no differences observed in chemical composition of most and wine, as well as sensorial properties of the wine from conventional and organic variant, no matter of climatic region.
