dc.descriptionTobacco is a crop of great commercial value for Ecuador, among the varieties that are planted the most in the country are: Virginia with an approximate hectare of 800 ha and Burley with about 300 ha planted, known in the market as rubios, and the layer tobacco (1000 ha) the same one that is more complicated to produce than the previous ones, since it is more demanding in terms of leaf quality. The present experimental work was carried out on the land of the “Intabaco” farm owned by Eng. Javier Guizado, located in the Montalvo canton, Los Ríos province. It was sought to determine the effect of nitrogen and potassium on the agronomic behavior of tobacco (Nicotiana tabacum) in the variety “habana 2000. The variety“ habana 2000 was used as plant material. With this, the effects of the doses of the products on agronomic behavior. The randomized complete blocks experimental design was used, with 17 treatments and three repetitions. The variables were evaluated: plant height, stem diameter, leaf length, leaf width, leaf area and leaf weight. The variables evaluated were exposed to the analysis of variance, and the Tukey test was applied at 5% significance to determine the statistical difference between the means of the treatments. Once the experimental results were indicated, statistical significance was achieved in all the variables. The treatment Urea 200 kg / ha + Muriate of potassium 50 kg / ha (91.50 cm2) presented the largest foliar area and generated greater weight of tobacco leaves.es_ES

dc.description.abstractEl tabaco es un cultivo de gran valor comercial para el Ecuador, entre las variedades que más se siembra en el país están: Virginia con una hectáreaje aproximado de 800 ha y Burley con unas 300 ha sembradas, conocidos en el mercado como rubios, y el tabaco de capa (1000 ha) el mismo que resulta más complicado producirlo que los anteriores, ya que es más exigente en cuanto a la calidad de hoja. El presente trabajo experimental se realizó en los terrenos de la finca “Intabaco” propiedad del Ing. Javier Guizado, ubicada en el cantón Montalvo, provincia de los Ríos. Se buscó determinar el efecto del nitrógeno y potasio en el comportamiento agronómico del tabaco (Nicotiana tabacum) en la variedad “habana 2000. Como material vegetal se empleó la variedad “habana 2000. Con esto se evaluó los efectos de las dosis de los productos sobre el comportamiento agronómico. Se utilizó el diseño experimental bloques completos al azar, con 17 tratamientos y tres repeticiones. Se evaluaron las variables: altura de planta, diámetro de tallo, longitud de hoja, ancho de hoja, área foliar y peso de hoja. Las variables evaluadas fueron expuestas al análisis de varianza, y se aplicó la prueba de Tukey al 5% de significancia para determinar la diferencia estadística entre las medias de los tratamientos. Indicados los resultados experimentales se logró significancia estadística en todas las variables. El tratamiento Urea 200 kg/ha + Muriato de potasio 50 kg/ha (91,50 cm2) presento la mayor área foliar y generó mayor peso de hojas de tabaco.es_ES
