Effect of Nitrogen and Sulphur Fertilisation on Microbiological Parameters of Milk Thistle Achenes

Popis výsledku v původním jazyce

The achenes of milk thistle (Silybum marianum (L.) Gaertn.) are used in pharmaceutical and cosmetic products, as well as an ingredient of functional food and animal feed because they contain a variety of lipids, proteins and biologically active substances. The quality of seeds of milk thistle is not only given by contained substances but also by their microbiological purity. The objective of the vegetation experiment established in 2016 was to explore the effect of nitrogen (N) and sulphur (S) fertilization on microbiological quality of milk thistle seeds. Six treatments were established in the experiment: 1. N2S0, 2. N3S0, 3. N2S2, 4. N3S3, 5. N1S1+N1S1 and 6. N2S2+N2S2 (where: N1 - 25 kg/ha, N2 - 50 kg/ha, N3 - 100 kg/ha, S0 - without sulphur fertilization, S1 - 12.5 kg/ha, S2 - 25 kg/ha, S3-50 kg/ha). Variants 1-4 were treated with nitrogen and sulphur before sowing using one dose of fertilizer. Split doses application was applied at variants 5 and 6 fertilizing before sowing and at the beginning of extensive growth during elongation and branching of plants. In milk thistle achenes collected in the period of maturity of terminal flowerheads, these groups of microorganisms were determined: aerobic plate count, thermoresistant aerobic microorganisms and moulds. Protective effect of the applied sulphur against moulds and thermoresistant aerobic microorganisms on the seed was observed, but it was not significant. The aerobic plate count was not affected by fertilization.
