Abstract
The importance of peat-free cultivation has been increasing recently, and testing the possibilities and procedures to improve it aligns with modern research trends.
The aim of the experiment was to determine the influence of commercially available substrates (rock wool and coconut fiber) on the qualitative and quantitative parameters of selected microgreen species (Eruca sativa, Lepidium sativum, Brassica rapa var. japonica, Raphanus sativus, and Ocimum basilicum). The evaluated parameters were fresh biomass yield, dry yield, and chlorophyll a and b content.
The experiment was conducted in January 2021 in the climatic chamber with a phytotron system KK 750 FIT P. When the cotyledon leaves were fully formed, microgreens were harvested, weighed, and analyzed.
Results show that the substrate did not have a significant effect on fresh matter yield, with an average of 7.77 g FW on coconut fiber and 8.94 g FW on rock wool.
The substrate also had a significant effect on chlorophyll content.
Results from variants grown on rock wool were significantly higher (428.484 mg kg‑1 FW chl a, 184.022 mg kg‑1 FW chl b) compared to coconut fiber (391.027 mg kg‑1 FW chl a, 159.640 mg kg‑1 FW chl b).
