Resumen

Within the agricultural sector, the biol resulting from anaerobic digestion has a great source of benefits for different plant crops. So much so that in recent research, biol has been the subject of study and used in a great way as a fertilizer for different food plants. The use of organic fertilizers is important because they allow the stable production of crops without affecting the soil, and in this way the agricultural process affects the environment to a lesser extent. For this reason, the objective of this research work was to evaluate the effect of the application of Biol obtained from the mixture of biols from biodigesters of coffee farms in the department of Tolima at different concentrations on the common bean. In order to analyze the best performance for the growth of this plant. In order to achieve this objective, the biol produced and the soil were characterized by means of laboratory studies. Then, a completely randomized design (CRD) was carried out with 3 treatments and a control, each with 5 bean plants planted in pots and periodically irrigated with different concentrations of biol (25%, 50%, 75%, control without application). In addition, morphological variables were measured periodically (every 5 days) and yield variables at the end of the crop cycle. Thus, by means of analysis of variance and Fisher's LSD test (N.C 95%) or non-parametric Kruskall Wallis test, the best concentration of biol for the development of the bean crop was obtained.
