The work aimed to analyze the effects of soil liming on the productivity of the mixture of tall oat grass and red clover during the entire period of exploitation in order to develop sustainable management systems in agriculture. The trial was conducted from 2014 to 2020 on the experimental field in Čačak on an alluvial soil with an acid reaction. The trial was set up as a completely randomized block system with four replicates and a plot size of 5x1 m. Levels of liming included: A1 – control (without CaO); A2 – 3 t ha-1 CaO; A3 – 6 t ha-1 CaO. Crop response to soil liming was determined by the amount of lime applied, the amount of rainfall and the developmental stage of the species during the life cycle. In concrete conditions, the greatest positive effect of soil liming was observed in the second and third years of production. And if it was expected that the proportion of clover and the intensity of nitrogen fixation generally increase with the application of soil liming, this study showed that in some cases the crop responded differently and non-linearly to the application of lime. By growing red clover in a mixture with tall oat grass and applying soil liming on acidic soils, satisfactory yields can be achieved while recovering the soil from intensive exploitation, which can be good practice for developing a sustainable management system in agriculture.
