The success of reforestation depends on the production of quality seedlings in nurseries. Initial fertilization and mycorrhization are determinants that improve the growth of plants. The purpose of this study was to improve the quality of Ceiba pentandra seedlings using fertilization and mycorhization in nurseries. Seedlings of C. pentandra were subjected to various treatments (T1: Sterilized forest soil (100 %), T2: 90 % T1 + sterilized mycorrhizal inoculum (10 %); T3: 90 % T1 + mycorrhizal inoculum (10 %); T4: 90 % T1 + compost (10 %); T5: 80 % T1 + mycorrhizal inoculum (10 %) + compost (10 %)). The results showed an increase of 117.35 % in the dry stem weight of young Ceiba pentandra mycorrhizae (T3) seedlings compared to non-mycorrhizae (T2) seedlings. Growth parameters, roots, total leaf area were better with the treatment combining mycorrhization and compost application. Furthermore, the sturdiness quotient was identical for all substrates. Seedlings of Ceiba pentandra are highly dependent on mycorrhization. For rapid production of quality seedlings, fertilization could be coupled with mycorrhization.
