In line with the needs of the Green Deal, Europa's Common Agricultural Policy follows the strategy for sustainable agriculture. The biostimulators, which are gaining increasing popularity, are an essential tool for ensuring an integrated approach of all agricultural raw materials. The aim of the present study is to investigate the effect of the biostimulators Speedb and Amino Expert® Impuls, as well as of the foliar fertilizer and immunomodulator Acramet Ultra on the elements of productivity, yield of fresh inflorescences, essential oil content and composition of Salvia sclarea. The experiment was arranged according to the randomized block method in four replications with plot size of 15 m2. The used products affected positively the productivity, as the treatment with Speedb led to highest increase in the yield of fresh flower spikes with 25% when comparing with the control. Only the treatment with both biostimulators increased the essential oil content, as the highest values were obtained when using Amino Expert Impuls. Based on the results, the products could be recommended and successfully used depending on the production direction.
