- Abstract
The use of agricultural residues for seedling production stands out as an effective sustainable alternative in the production of vegetables. The aim of this research was evaluate concentrations of wastes from the coffee bean drying process (moinha) in substrates composed of coconut fiber, eggshell and commercial substrate on the emergence and quality of scarlet eggplant (Solanum gilo) seedlings. An experiment was conducted in a completely randomized design with five treatments and ten repetitions. Thus, the following treatments were evaluated: T0 - commercial substrate Bioplant?; T1-15% of moinha (MO) + 15% of coconut fiber (CF) + 5% of eggshells (ES) + 65% of commercial substrate (CS); T2 - 30% MO + 15% CF + 5% ES+ 50% CS; T3 - 45% MO + 15% CF + 5% ES + 35% CS; and T4 - 60% MO + 15% CF + 5% ES + 20% CS. The emergence speed index, seed emergence, number of leaves, seedling height, stem diameter, shoot, root and total dry mass, Dickson's Quality Index and the electrical conductivity of the substrates were evaluated. The addition of moinha concentrations above 15% promotes an increase in electrical conductivity compared to the control and negatively affects seedling emergence. Among all treatments, 38% of moinha promotes an increase in the number of leaves, and 15% of moinha results in higher plant height, stem diameter, and the highest dry mass accumulation. The alternative substrate containing 15% MO + 15% CF + 5% ES + 65% CS promotes a better development for scarlet eggplant seedlings, being an alternative to the exclusive use of the commercial substrate.
