Objetivou-se neste trabalho avaliar o substrato e a disponibilidade de água no potencial germinativo das sementes de uvaia (Eugenia pyriformis). Os substratos avaliados foram: areia (A), latossolo + areia (L + A) (1:1), latossolo + areia + cama de frango semidecomposta (L + A1 + CF) (1:1:0,5), latossolo + areia + cama de frango semidecomposta (L + A2 + CF) (1:2:0,5), latossolo + Bioplant® (L + B) (1:1) aliados aos seguintes níveis de irrigação 25, 50, 75 e 100% da capacidade de retenção de água. As maiores porcentagens de emergência e melhor crescimento de plântulas foram observados no substrato latossolo + areia + cama de frango (1:2:0,5), na capacidade de retenção de água de 50%.<br>The objective of this study was to evaluate the substrate and water availability on germinative pontential of Uvaia (Eugenia pyriformis) seeds. The substrates evaluated were the following: Sand (S), Latosol + sand (L + S) (1:1), Latosol + sand + semi-decomposed chicken litter (L + S1+ CL ) (1:1:0.5), Latosol + sand + semi-decomposed chicken litter (L + S2 + CL) (1:2:0.5), Latosol + Bioplant® + (L + B) (1:1) joined to the following water levels: 25, 50, 75 and 100% the ability to retain water. The highest percentage of emergence and the best seedling growth were observed in substrates Latosol + sand + chicken litter (1:2:0.5) and water retention capacity of 50%.
