The goal of this project was to determinate the causes, consequences and solution of shortcomings in agricultural work, specifically in the classification of bulb onion, which resulted than the deficiency occurs for the lack of technical prototypes to facilitate this development, current methods require more staff, increasing the production costs In the harvest process, the numbers determinate, what the most requires time is the size selection process of product, since the regional brokers demands three different groups of onion classified by their size, according to an archetype of the product whit mandatory characteristics for the commercialization, making the cost production higher. These backgrounds show the relation between the design of this project and the different ways used to classified onion, so this project has as final goal make a contribution in agronomic sector in Colombia, a sector which represents an important economic base for a major portion of population. In the oncoming project, the process to be implemented is announced, the objectives set are declared for each area, a set different comparative angles whit the development of the prototype, also we emphasize in the national legal regulatory framework, looking to encourage the local and independent production in Boyacá, in the end we set the conclusion of the proposal and the answers of the project
