The propagation of banana seedlings in nurseries is an essential practice to increase productivity in a shorter period. This study aimed to determine the influence of corm size on the initial growth of Williams banana seedlings. The research was conducted at the “La María” Campus of the Universidad Técnica Estatal de Quevedo, Ecuador, between November 2022 and February 2023. A total of 150 corms were planted in controlled conditions using a specific substrate. The corms were classified into three categories: small, medium, and large. Growth parameters such as height, diameter, fresh and dry biomass, number of leaves, and phyllochronic index were evaluated. Results indicated that larger corms significantly increased plant height and diameter compared to smaller and medium-sized corms. Additionally, larger corms contributed more to biomass accumulation in seedlings. However, no significant differences were observed in the number of leaves among treatments. The phyllochronic index was influenced by corm size, with an average of 7.72 days to produce a new leaf. The use of larger corms resulted in more vigorous and uniform banana seedlings, facilitating their adaptation to the field in less time.
