Resumen

La seguridad en la producción agrícola es uno de los parámetros cruciales para las frutas y hortalizas, que se consigue a través de la agricultura sostenible. En este estudio se evaluó la cianobacteria Anabaena en simbiosis con la planta Azolla sp, para el desarrollo de un biofertilizante. Se recolectaron muestras en Cusubamba, Pichincha, y se probaron siete medios de cultivo con diferentes aportes nutricionales. En el estudio de Azolla se analiza el peso inicial y el peso final para medir el crecimiento, el tiempo para evaluar el desarrollo y el área de cultivo, que determina la superficie disponible para la determinación de biomasa. El conjunto de estas variables permite evaluar el rendimiento y la sostenibilidad de Azolla. El mejor tratamiento fue T2 (Nitrofoska 1g), alcanzando 66,59 g de peso fresco, una tasa de crecimiento de 3,83 g/d y un tiempo de duplicación de 5,96 días. El método Dumas mostró que el T2 concentraba aproximadamente un 5% de nitrógeno. El biofertilizante cumplió con las características y normas de calidad de la Agencia de Regulación y Control Fitosanitario y Zoosanitario (Agrocalidad-Ecuador), como la ausencia de microorganismos patógenos y la presencia de macro y micronutrientes como el nitrógeno, que presentó un porcentaje promedio de 1,54%, además de parámetros físicos moderadamente óptimos como un pH de 4,68 y una densidad de 0,016 g/mL.
