Sažetak
Investigations were carried out on semigley in the central River Drava valley (Northern Croatia) with the aim of establishing the fertilizing value of Biopost, as a representative of organic fertilizers, and of Organo, as representative of organic-mineral fertilizers, in comparison with mineral fertilizers and stable manure, the latter two being compared with each other as well regarding the yield and quality of flue-cured tobacco leaf. Efficiency of the fertilizer types and rates applied was strongly affected by very adverse meteorological conditions, which often showed characteristics of severe drought. Nevertheless, under such conditions and despite the minimum rates applied, Biopost and Organo had a positive effect on the yield and quality of the flue-cured tobacco leaf. In all cases, they had an obvious advantage over mineral fertilization, offering distinct possibilities of their application in the growing of flue-cured tobacco. However, owing to its better fertilizing efficiency, combined organic and mineral fertilization might be justified, certainly also with respect to the economic aspect of the problem. The positive influence of Biopost and Organo on the higher participation of quality classes of flue-cured tobacco leaf in comparison with mineral fertilization is indisputable despite the occasionally prevailing effects of fluctuating weather conditions during the investigation period. In other words, harmonic organic, even organic-mineral, fertilization should be preferred to mineral fertilization alone.
