In Vietnam, a source of local bio-materials that could be used to replace imported peat, resulting in more affordable growing substrates. Several growing substrates for Brassica microgreens were evaluated in this study: GT1 (30% sand +20% organic soil + 50% coco coir), GT2 (75% coco coir + 25% rice husk), GT3 (75% coco coir + CaO 2.2 mg/kg + acid humic 0.41%) and imported peat GT4 (75% white sphagnum peat +25% vermiculite (size 4–6 mm). The local organic material coco coir GT3 was found to be as effective as the imported substrate for microgreen production. The material coco coir mixed with soil and sand could increase the risks of soil-borne disease infestation on <em>Brassica </em>microgreens. Microgreens grown in the substrate GT3 and GT4 had higher productivity and lower disease infestation levels than other tested substrates. Nitrate level and microbiological contamination (<em>E. coli </em>and <em>Salmonella </em>spp.) of <em>Brassica </em>microgreens cultivated in these substrates were determined to be at safe levels.</p>}, number={2}, journal={Academia Journal of Biology}, author={Hoang, Gia Minh and Vu, Thuong Thi}, year={2022}, month={Jun.}, pages={133–142} }
