Action Research in the Cultivation of Radish (Raphanus Sativus L.) using the Phytoremediation Technique

Abstract

The research work was developed with students of the VI semester of the Biology and Chemistry program of the UNDAC, Chemistry Laboratory course, the objective was to apply action research, as a working method in the teaching-learning process for the recovery of the soils of the Yanamate Lagoon contaminated by mine tailings,  through phytoremediation processes using radish cultures (Raphanus sativus L.). The research is applied and the design is quasi-experimental with two groups. The sample consisted of 21 plants in 40x50 plots, with 5cm between plants and 10cm between rows. The results show a weight/plant of 0.657 gr/plant for the experimental group compared to 0.834 gr/plant in the control group, plant size 25 cm in the control group and 38 cm for the experimental group. Metal absorption indicates an increase of 6.5% for the experimental group. Yield of 57.3% in the experimental group for number of radishes per plant. It is concluded that students improve by 85% the use, application of phytoremediation techniques and action research, teaching and learning increases by 92%, because they learn by doing.
