dc.descriptionThis research work was carried out on the premises of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at km. 7.5 of the Babahoyo-Montalvo road. The geographical coordinates in UTM were X: 1,7723946; Y: 79.7102593. The area has a humid tropical climate, with a temperature that ranges between 24 and 26 ° C, with relative humidity of 88%, average annual rainfall of 1262 mm, with a height of 8 meters above sea level and 990 hours of annual average heliophany. As evaluation material, weed plants were used, from the material irradiated at 52 Gy of gamma rays (60 Co). In this investigation, a "Random Complete Blocks" Design was used, with five treatments and four repetitions, the variables evaluated were: plant length, leaf length, leaf width, leaf area, stem diameter, number of leaves , wet weight yield, dry weight yield, dry matter yield percentage (RMS). In the present investigation it was possible to determine what the fertilization dose applied in the T3 treatment (Urea 300 Kg / ha) showed highly significant statistical differences in number of leaves, wet weight and dry weight with respect to T5 (0 Kg / ha) that was the control with dose 0. With respect to the agronomic variables: leaf width, stem diameter, percentage of dry matter yield, they did not present statistical significance and the results show that the T5 treatment (0 Kg / ha presented numerically the lowest Averages Numerically the treatment T3 (Urea 300 Kg / ha) surpasses all the treatments in the variables plant length, leaf length, leaf area.es_ES

dc.description.abstractEl presente trabajo de investigación se realizó en los predios de la Facultad de Ciencias Agropecuarias de la Universidad técnica de Babahoyo, ubicada en el km. 7.5 de la vía Babahoyo-Montalvo. Las coordenadas geográficas en UTM fueron X: 1.7723946; Y:79.7102593 . La zona presenta un clima tropical húmedo, con una temperatura que oscila entre los 24 y 26 °C, con humedad relativa de 88%, precipitación promedio anual de 1262 mm, con altura de 8 msnm y 990 horas de heliofanía de promedio anual. Como material de evaluación se utilizó plantas de pasto janeiro, provenientes del material irradiados a 52 Gy de rayos gamma (60 Co). En esta investigación se utilizó un Diseño de “Bloques Completos al Azar”, con cinco tratamientos y cuatro repeticiones, las variables evaluadas fueron: longitud de la planta, longitud de hoja, ancho de hoja, área foliar, diámetro del tallo, numero de hojas, rendimiento peso húmedo, rendimiento peso seco, porcentaje de rendimiento de materia seca (RMS). En la presente investigación se pudo determinar qué la dosis de fertilización aplicado en el tratamiento T3 (Urea 300 Kg/ha) mostro diferencias estadísticas altamente significativas en número de hojas, peso húmedo y peso seco con respecto al T5 (0 Kg/ha) que fue el testigo con dosis 0. Con respecto a las variables agronómicas: ancho de hojas, diámetro de tallo, porcentaje de rendimiento de materia seca, no presentaron significancia estadística y los resultados muestran que el tratamiento T5 (0 Kg/ha presento numéricamente los menores promedios. Numéricamente el tratamiento T3 (Urea 300 Kg/ha) supero a todos los tratamientos en las variables longitud. de planta, longitud de hojas, área foliar.es_ES
