The research was carried out on fields of farm AGRO SAP s.r.o. located in Nenince near the town VeÄžkĂ˝ KrtĂ­ĹĄ in 2020-2022. The design of experiment was based on randomized split plot method in three repetitions, with a plot size 3 m × 20 m. The aim of experiment was found out effect of two vermicompost-based preparations T1 and T2 on two sunflower hybrids H1 and H2. Evaluated parameters were yield-forming elements (number of plants, diameter of heads, weight of head, thousand seed weight), seed yield and oil content. Use of vermicompost-based preparation T2 had significant impact on increase of yield-forming elements (diameter of head 17.29 ± 1.41 cm; weight of head 180.22 ± 18.90 g) and seed yield 3.68 ± 0.70 g, compared to untreated variant. The highest value of thousand seed weight (65.33 ± 2.40 g) and oil content (39.49 ± 1.91%) in three experimental years was achieved on treated variants by vermicompost-based preparation T1. Two used sunflower hybrids influenced all monitored experimental parameters, and significantly higher values were recorded in hybrid H1, except oil content (39.63 ± 1.86%). The evaluation of correlation analysis demonstrated the high positive relation between weight of head and diameter of head, seed yield and thousand seed weight. As a result, the use of vermicompost-based liquid fertilizers has positive effect on increase values of yield-forming elements, production and quality of sunflower.
