Abstract
Cacao is a strategic crop in Ecuador due to its economic and social importance, making it necessary to incorporate sustainable alternatives that enhance its productivity. The study was conducted in Buena Fe, Los Ríos, Ecuador, on land owned by the Maquita Cushunchic Foundation (MCCH), with the aim of evaluating the effect of organic biostimulants based on humic acids on the production of CCN-51 cacao. A completely randomized block design was applied with five treatments: T1, Ferti Producción 2 L/ha; T2, Ferti LAC 2 L/ha; T3, Ferti Plus 2 L/ha; T4, Producción + Algas 2 L/ha; and T5, water. Phenological, phytosanitary, productive, and economic variables were evaluated. T2 showed the best performance with 23 suckers, 5 flowers, 5.6% cherelle wilt, 7.64% Phytophthora spp., 6.25% moniliasis, 119 healthy pods, and 2,210.32 kg/ha. In addition, it recorded a benefit-to-cost ratio of 5.00 and a profitability of 399.95%, reflecting its potential as a sustainable alternative to improve crop productivity and economic efficiency.
