Abstract: The reuse of materials in agricultural practices is increasingly important in the context of mitigating environmental impact and promoting sustainability. In this way, promoting the use of agricultural residues as substrates for the production of coffee seedlings represents an economically viable source of nutrients. Arabica coffee (Coffea arabica L.) ranks as the second most valuable product on the global market, and is widely consumed throughout the world. Thus, the objective of the present work was to evaluate the litter from the Compost Barn cattle confinement system in the composition of substrates for the production of Arabica coffee seedlings (Coffea arabica L.) in a protected environment. The contour was in a chapel- type greenhouse, with a total area of 233.3 m² oriented in the East-West direction, covered by low-density polyethylene experiment film, 150 μm thick. The experimental design was randomized 2x5, corresponding to two cultivars and five substrates. Seedling evaluations were carried out 180 days after the week. Micrometeorological data were obtained using automatic and direct reading sensors in greenhouses. For the external environment, data were obtained from the automatic meteorological station at the Federal University of Lavras. The interaction between substrate and cultivar exerted a significant influence on most agronomic variables, resulting in good plant development. The micrometeorological variables evaluated in the growing house and external environment were evaluated. It was evident that the global radiation intercepted increased progressively over the months, providing an increase in the capacity of Arabica coffee changes to intercept solar radiation. The base temperature demonstrated remarkable uniformity in the thermal development conditions of Arabica coffee seedlings in different treatments. On the other hand, the phyllochron showed the need for different amounts of thermal energy to produce a pair of leaves. Therefore, the choice of substrate plays a crucial role in the production of Arabica coffee seedlings. The interaction between substrate and cultivar is a determining factor in the success of plant development. Furthermore, micrometeorological analysis contributed to a more comprehensive understanding of environmental conditions during the experiment.
