In this study, the vegetative development of Daucus carota L. (carrot) and LactucaÂ sativa L. (lettuce), cultivated with techniques of clean agriculture and conventional techniques,Â was determined taking into consideration the number of leaves and the weightÂ of fresh and dry biomass of the samples. For Daucus carota L, the width and length ofÂ the root were established, and for Lactuca sativa L, the length and width of the leaves,Â and the height of the plant. The nutritional quality of both vegetables was evaluatedÂ and the presence of pesticides in the plants cultivated with the two different agriculturaltechniques was analyzed. The research demonstrated that the lettuce cultivated withÂ the technique of clean agriculture requires more time to reach its optimal developmentÂ that the lettuce cultivated with conventional methods; meanwhile the technique appliedÂ for Daucus carota L, has no influence on its time of development. The method of productionÂ of the vegetables does not generate significant differences among the group ofÂ nutrients that were analyzed, except for the content of gross fiber. The pesticide retentionÂ was prominent in the carrot cultivated by conventional techniques. Additionally, theÂ study permitted to instruct the student population of the Canyon of Combeima (Cañóndel Combeima, Ibagué-Tolima) in the topics related to the clean agriculture, with theÂ purpose of contributing to the betterment of the quality of life.
