| dc.description | Among the development of the case is the agronomic management of the pearl onion (Allium cepa L.) crop and its value-added processes. The bulb onion plantation has been in our country for many decades, becoming a labor crop because for its execution it requires sowing from the seedbed, completing many tasks and ending with the harvest. However, farmers try as much as possible to add value to the product in order to obtain higher economic income or profitable net benefit. Due to the foregoing, it is concluded that the technological management of the crop has been maintained since remote times, beginning with the preparation of the seedbed, transplantation, irrigation, fertilization, control of pests, diseases and harvest; For the preparation of the seedbed, beds of 1 m by suitable length are generally made and raised 15 cm from the ground level; for transplantation, the soil is disinfected and vigorous plants with a depth of 3 to 5 cm are transplanted at 80 - 90 days after sowing in the seedbed; the waterings are frequent, taking care not to flood the seedlings; Conventional fertilization is 50 kg / ha of urea and for the control of pests, diseases and weeds, chemical pesticides are applied with the appropriate dose and time of application, depending on the damage threshold; The harvest of onion bulbs begins when 50% of the stems have doubled due to maturity and the production of pearl onion with added value is limited, because farmers do not see it beneficial to sell their products in the markets of the Ecuador, trying to enter factories for export. | es_ES |

| dc.description.abstract | Entre el desarrollo del caso se tiene el manejo agronómico del cultivo de cebolla perla (Allium cepa L.) y sus procesos de valor agregado. La plantación de cebolla de bulbo radica en nuestro país desde hace muchas décadas, constituyéndose como un cultivo laboral porque para su ejecución necesita de la siembra desde el semillero, cumplir muchas labores y finalizando en la cosecha. Sin embargo, los agricultores tratan en lo posible en dar valor agregado al producto para poder obtener mayores ingresos económicos o beneficio neto rentable. Por lo expuesto anteriormente se concluye que el manejo tecnológico del cultivo se mantiene desde épocas remotas, iniciando con la preparación del semillero, trasplante, riego, fertilización, control de plagas, enfermedades y cosecha; para la preparación del semillero generalmente se hacen camas de 1 m por longitud adecuada y levantadas a 15 cm del nivel del suelo; para el trasplante se desinfecta el suelo y se trasplantan plantas vigorosas con 3 a 5 cm de profundidad a 80 – 90 días después de la siembra en semillero; los riegos son frecuentes, cuidando el no encharcamiento de las plántulas; la fertilización convencional es de 50 kg/ha de urea y para el control de plagas, enfermedades y malezas se aplican pesticidas químicos con dosis y época de aplicación adecuada, dependiendo del umbral de daño; la cosecha de los bulbos de cebolla comienza cuando el 50 % de los tallos se han doblado por efecto de la madurez y la producción de cebolla perla con valor agregado es limitada, debido a que los agricultores no ven beneficioso vender sus productos en los mercados del Ecuador, tratando de ingresarlo a fábricas para exportación. | es_ES |
