Evaluación del efecto biofertilizante de la harina de sangre obtenida mediante secado en el cantón Morona

Abstract

The current research had the objective of evaluating the biofertilizer effect of the blood meal obtained by drying. Through its formulation and analysis compared the effect caused in the soil of lettuce crops using a completely randomized design (CRD) with four treatments and three replicates with doses of 0%, 5%, 10%, and 15%. These percentages of biofertilizer were placed in the soil in order to transplant the crespa lettuce seeds. For the analysis of the soil, it took a sample of each treatment as a reference before and after the end of the research. The data collected for the variables: height, number of leaves and coloration were collected 25 and 50 days after transplanting the seeds. The final results by means of the statistical analysis of variance and test of Tukey (5%) allowed determining that there are significant differences in height at 25 days after transplanting; obtaining the T1 a value of 8.3 cm in height, while the T0 obtained better results at 50 days with 9.67 cm as well as the number of leaves. The T0 presented better values with respect to the T1, T2 and T3. The results corresponding to the soil showed decreases and increases in their values, highlighting T3 with an increase in electrical conductivity (EC), nitrogen (N) and iron (Fe), while the hydrogen potential (pH) presented very low values of 4.97% and 4.83%, being qualified as very acidic. Finally, it concluded that the application of the biofertilizer in the soil as a nutrient component with a 5% concentration achieved favorable results during the first 25 days, maintaining small differences in its values until day 50 corresponding to the harvest.
