Abstract: Treatment of plants with mineral-organic concentrates has developed intensively in recent years. Fertilizers containing, among others, humus, L-amino acids, vitamins, chelates and metal complexes, macro-, micro- and meso-elements, organic matter and humic acids from the top organic layer of leonardite coal have a positive effect on plant growth and quality and seed yield. An experiment was conducted between 2019 and 2022 at the University of Agriculture in Kraków, in which the impact of mineral-organic concentrate on the seed yield and quality of perennial ryegrass ( Lolium perenne L.) 2N Bokser (Hodowla Roślin Grunwald Ltd. Grupa IHAR, Grunwa, Poland) was determined. As part of the experiment, plants were sprayed with a mineral-organic product in three different doses: 1.0, 2.0 and 3.0 L·ha −1 . The following parameters were examined: the number of generative shoots, the length of the flag leaf, seed yield, germination capacity and the weight of one thousand seeds. It turned out that the application of the concentrate with 3 L·ha −1 and 2 L·ha −1 led to a significant increase in the number of generative shoots and in seed yield, compared to control. In addition, seed germination capacity of fertilized plants was higher, with the greatest increase after the application of 3 L·ha −1 . Moreover, the average weight of one thousand seeds was significantly higher in fertilized plants, compared to the control, and the largest increase was recorded in response to the highest dose. The results indicated a positive effect of the organic-mineral concentrate on perennial ryegrass development parameters and seed quality.
