Aprovechamiento de residuos de mucílago de cacao (Theobroma cacao L.) y café (Coffea arabica) como herbicida para el control de malezas

The main objective of this study was to evaluate the influence of cocoa (Theobroma cacao L.) and coffee (Coffea arabica) mucilage for its use in the development of a herbicide and weed control. To carry out the study, the following methods were used: statistical, bibliographic and deductive, as well as techniques through experimentation and observation. A scientific research analysis was conducted to identify the different uses of these agricultural residues, data collection on rural production so that cocoa mucilage generated in the study area is approximately 120 liters of this by-product that is generated in each harvest cycle on two hectares and, unlike the shell, cocoa mucilage is recognized as a strategic resource. A completely randomized design with 4 treatments and 3 replications was applied, where the study factor A is mucilage and factor B is concentration, whose variables were weed control and the dose of cocoa and coffee herbicide. The results revealed that for the FA*FB interaction, there is a significant difference between the cocoa mucilage groups with its 100% concentration, which showed the highest mortality after the third application, reaching 97% mortality of the weed (Petiveria alliacea L.). As for the economic valuation, the total cost of the cocoa herbicide in this study was determined at $27.24 per 20 L of cocoa mucilage extract (Theobroma cacao L.).
