Abstract In Ecuador, the favorable climatic and ecological conditions allow small, médium and large producers to dedícate themselves to the exploitation of bananas and plantains. Inthe case of the orito, it is a special fruit, of great acceptance for its flavor and aroma. The plantations are found as monocultures in some cases and in others, as associations that are interspersed with different fruit species and timber trees. The different banana species reproduce asexually from vegetative fractions. On the other hand, the use of organic fertilizers is due to the fact that they are a source of bacterial life for the soil and are necessary for the nutrition of plants. They are obtained from the degradation and mineralization of organic materials (manure, kitchen waste, etc.). The different types of bioles are prepared with different manures that must be fermented for two to three months in a plástic container, it is a fertilizer that allows to replace a large part of chemical fertilizers. With this background, the present investigation aimed to evalúate the effect of two liquid organic fertilizers (worm manure liquid based on cow dung (HLV) and beef manure tea (TEV) at a concentration of 75% on the development of corms of orito (Musa acuminata AA) to obtain plants in a fast way and establish cash crops for the conditions of Cantón Cumandá province of Chimborazo The trial was conducted in a randomized blocks design with 3 treatments and 3 repetitions. root mass in g (PMR), root volume in mi (VR), root length in cm (LR), leaf length in cm (LH), foliage weight in g (PF) and leaf width in cm (AH) Every 14 days, evaluations were made from 111 days to 181 days for the development of the corms The variables evaluated did not show significant differences until 167 days. in the PMR, VR, PF, LH and AH, while the LR did not show significant differences. The best response was obtained with the HLV, which surpassed the TEV and the control (T). The outstanding valúes were found at 181 days for: PMR with 110.6 g, VR 110 ml, PF 205 g, LH 36 cm, AH 15.5 cm, LR 59.5 cm. do not show significance with the other treatments.
