F. de S.  aEvaluation of millicomposts from different vegetable residues and production systems in the lettuce seedling development.h[electronic resource]  c2021  aThe final product of millicomposting is millipede humus, which has been called millicompost and can contribute to supply the growing demand for substrates used to produce vegetable seedlings in rural and urban environments. In this context, this study aimed to verify the efficiency of millicomposts obtained in two different production systems, located in different environments (Rio de Janeiro and São Paulo) with different diplopod species in the production of lettuce seedlings. Initially, a thorough characterization of the evaluated substrates was carried out, characterizing the physical, physical-chemical, and chemical properties. The performance of different substrates in the production of lettuce seedlings was evaluated by sowing crisp lettuce cultivar Grand Rapids in 200-cell expanded polystyrene trays. The seedlings were evaluated 30 days after sowing. Millicomposts produced in RJ and SP states have differences in their physical, physical-chemical, and chemical properties. Nevertheless, both produced lettuce seedlings with similar quality, whose phytotechnical parameters were superior to the commercial substrate. In this point of view, both millicomposts are efficient as a substrate in the production of lettuce seedlings and can be produced in rural and urban environments, meeting the current need for sustainable agricultural inputs.  aHorticulture  aLactuca sativa var. longifolia  aOrganic wastes  aDiplopods  aMillicomposting  aOrganic substrates1 aSOUZA, R.
