Optimización de un biofertilizante a base de (Padina pavonica) para mejorar el crecimiento de la lenteja (Lens culinaris) y el Frejol (Vignna unguiculata) en condiciones controladas.

Abstract

Biofertilizers based on macroalgae improve the growth of agricultural crops and at the same time contribute to the environment, being these a chemical-free option. An evaluation was carried out on lentil (Lens culinaris) and bean (Vigna unguiculata) crops, which were classified into 3 treatments, one of which was a control, to which a biofertilizer preparation based on Padina pavonica was applied in two different concentrations for the treatments. An experimental design was developed, where in the control treatment neither concentration was applied, in treatment 1 a concentration of 13.3 g/l was used and in treatment 2 a concentration of 26.6 g/l under controlled conditions. The plants treated with the prepared product show significantly greater growth than those of the control group. The biofertilizer proved to be effective in growth, validating its potential as a sustainable alternative to chemical fertilizers. The methodology included the collection of P. pavonica on the Barbasquillo beach, its processing and analysis in the laboratory. Statistical tests (ANOVA and Kruskal-Wallis) were performed to confirm significant differences. The treatment with the highest concentration (26.6 g/l) showed better results in both crops. The results highlight the capacity of macroalgae as ecological inputs, promoting agricultural sustainability and reducing dependence on agrochemicals. Thus, the biofertilizer based on the macroalga P. pavonica represents a promising innovation to improve crop productivity in a sustainable manner.
