Abstract : Zinc is an important microelement that enters into the composition of hundreds of enzymes and thousands of proteins in the plant and animal world. The aim of the study was to analyze the effect of foliar application of zinc in acid soil on the most important seed yield components and seed yield of selected red clover (Trifolium pratense L.) genotypes from Serbia and Bulgaria. The experiment was established in 2012 in Čačak (Serbia) on loessivized vertisol soil type with acid reaction (pHH2O 4.8). Sowing was done at a distance of 70x40 cm. There were used four different genotypes of red clover, three of which were isolated from the local population and variety of K-39. For the analysis was used the second cut in the second year of cultivation. Two treatments were used: control - no fertilization and foliar treatment with zinc in the form of ZnSO4 x 7H2O, at a concentration of 0.2%, using 1000 L ha-1 of water, at the stage of intensive plant growth. Foliar application of zinc had a positive effect on the number of stems per plant, the number of inflorescences per stem, the number of inflorescences per plant and the number of flowers per inflorescence. The negative effect of foliar application of zinc has been reported on the thousand seeds weight and the fertility of flowers at the genotypes originating from Bulgaria. A significant increase in seed yield per plant, under the influence of foliar application of zinc, was observed only in the variety K-39 (for 11.4 g plant-1), which otherwise had the highest seed yield.
