dc.descriptionTobacco is a dicotyledonous plant that came to Europe from America, being its first uses as an ornamental plant, then as a medicinal plant and finally used in the tobacco industries. In Ecuador, tobacco contributes 18% of the total income tax and 46% of the global collections of the consumption tax, as well as generating income for the country from its production, with an average yield of 2.24 metric tons per hectare. The areas of greatest cultivation are Simón Bolívar, Naranjal, Milagro, El Empalme, Mocache and Quevedo, the latter being areas that have adequate edaphoclimatic conditions for the production of tobacco cultivation. Knowledge of the fertility of the soil and the fertilization of the fields is of great importance in tobacco production, since the purpose of this is to produce a leaf with a well-defined chemical composition and certain physical conditions, capable of meeting the important requirement known as quality. The nutritional management of the crop is an essential tool of any modern production approach. The essential nutrients that most limit tobacco production systems are macroelements such as nitrogen, phosphorus and potassium. Tobacco cultivation in Ecuador is considered a crop that provides employment to many families due to the different activities that are developed to obtain the final product, it is also a crop that can contribute to the economic and social sector. Therefore, it is necessary to establish fertilization programs based on a soil analysis and nutritional requirement of the crop. Among the main nutrients that tobacco needs in the highest content are nitrogen, phosphorus and potassium; known as essential macroelements. Among the situations that arise in tobacco cultivation is mainly the execution of an edaphic fertilization program, application of the necessary elements that favor the phenology of tobacco cultivation, which acts at the same time as preventive measures against nutritional deficit that hinders the production of leaves, commercialization and development of plants.es_ES

dc.description.abstractEl tabaco es una planta dicotiledónea que llego a Europa desde América, siendo sus primeros usos como planta ornamental, luego como plantas medicinal y finalmente utilizado en las industrias tabaqueras. En el Ecuador el tabaco aporta el 18% del total del impuesto a la renta y el 46% de las recaudaciones globales del impuesto al consumo, como también genera ingresos al país por su producción, con rendimiento promedio de 2.24 toneladas métricas por hectárea. Las zonas de mayor cultivo son Simón Bolívar, Naranjal, Milagro, El Empalme, Mocache y Quevedo, siendo estas últimas, zonas que cuentan con condiciones edafoclimatica adecuadas para la producción del cultivo de tabaco. El conocimiento de la fertilidad del suelo y la fertilización de los campos tiene gran importancia en la producción de tabaco, puesto que la finalidad de esta es producir una hoja de composición química bien definida y de unas condiciones físicas determinadas, capaces de cumplir el importante requisito conocido como calidad. El manejo nutricional del cultivo es una herramienta esencial de cualquier planteo de producción moderno. Los nutrientes esenciales que en mayor medida limitan los sistemas de producción tabacalera son los macroelementos como el nitrógeno, el fósforo y el potasio. El cultivo de Tabaco en Ecuador es considerado como un cultivo que aporta empleo a muchas familias debido a las diferentes actividades que se desarrollas para obtener el producto final, también es un cultivo que puede contribuir en el sector económico y social. Por tanto, es necesario establecer programas de fertilización a partir de un análisis de suelo y requerimiento nutricional del cultivo. Entre los nutrientes principales que en mayor contenido los necesita el tabaco son el nitrógeno, el fósforo y el potasio; conocidos como macroelementos esenciales. Entre las situaciones que se presentan en el cultivo de tabaco esta principalmente la ejecución de un programa de fertilización edáfico, aplicación de los elementos necesarios que favorezcan la fenología del cultivo de tabaco, la cual actúa a la vez como medidas de prevención ante el déficit nutricional que dificulte la producción de hojas, comercialización y desarrollo de las plantas.es_ES
