| dc.description | The experimental work was carried out on the grounds of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at kilometer 7.5 of the Babahoyo - Montalvo road, located at a height of 8 masl at UTM X coordinates: 1.772 394 6 ; Y: 710 293, presents an average temperature of 24 - 26 ºC. The research had the general objective of evaluating the agronomic and productive response of the grassland irradiated at 52 Gy subjected to different levels of fertilization and cut frequencies, under Babahoyo conditions. Grass stolons were used. To obtain the results, the experimental design Completely Random Design (DCA) with a 5% statistical probability was used. According to the results, it was determined that for plant height, treatments 3 (0 Gy, 250 Kg of fertilizer and 35 days of cut) and 8 (52 Gy, 250 Kg of fertilizer and 45 days of cut) stood out with 2.77 m and the lowest value in treatments 1 (0 Gy, 0 Kg of fertilizer and 35 days of cut) and 6 (52 Gy, 0 Kg of fertilizer and 45 days of cut) with 1.49 m. Regarding stem diameter, a highly significant difference was recorded. The treatments were 7 (52 Gy, 250 Kg of fertilizer and 35 days of cut) and 8 (52 Gy, 250 Kg of fertilizer and 45 days of cut) with an average of 0.52 that presented the best results. Regarding number of clumps, treatment 2 (0 Gy, 0 Kg of fertilizer and 45 days of cut) with an average of 28.25 clumps, presented the highest value for this variable; the lowest value was for Treatment 6 (52 Gy, 0 Kg of fertilizer and 45 days of cut) with 24.5. Regarding the leaf width, it can be seen that treatment 8 (52 Gy, 250 Kg of fertilizer and 45 days of cutting) reached the widest leaf width with a value of 2.07 cm, the lowest value corresponded to the treatment 1 (0 Gy, 0 Kg of fertilizer and 35 days of cut) with a value of 1.34 cm. In the analysis of the variable % RMS, treatment 4 (0 Gy, 250 Kg of fertilizer and 45 days of cut) stood out with 33.60% and the lowest value is represented by treatment 5 (52 Gy, 0 Kg of fertilizer and 35 cut-off days) with 23.20%. | es_ES |

| dc.description.abstract | El trabajo experimental se desarrolló en terrenos de la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Babahoyo, localizada en el kilómetro 7.5 de la vía Babahoyo – Montalvo, ubicada a una altura de 8 msnm en las coordenadas UTM X: 1.772 394 6; Y: 710 293, presenta una temperatura promedio de 24 – 26 ºC. La investigación tuvo como objetivo general evaluar la respuesta agronómica y productiva del pasto Janeiro irradiado a 52 Gy sometido a diferentes niveles de fertilización y frecuencias de corte, bajo las condiciones de Babahoyo. Se utilizaron estolones de pasto. Para la obtención de los resultados se utilizó el diseño experimental Diseño Completamente al Azar (DCA) al 5 % de probabilidad estadística. Según los resultados se determinó que para altura de planta se destacaron los tratamientos 3 (0 Gy, 250 Kg de fertilizante y 35 días de corte) y 8 (52 Gy, 250 Kg de fertilizante y 45 días de corte) con 2.77 m y el menor valor en los tratamientos 1 (0 Gy, 0 Kg de fertilizante y 35 días de corte) y 6 (52 Gy, 0 Kg de fertilizante y 45 días de corte) con 1,49 m. Con respecto al Diámetro de tallo, se registró una diferencia altamente significativa. Siendo los tratamientos 7 (52 Gy, 250 Kg de fertilizante y 35 días de corte) y 8 (52 Gy, 250 Kg de fertilizante y 45 días de corte) con un promedio de 0.52 los que presentaron los mejores resultados. Referente a número de macollas, el tratamiento 2 (0 Gy, 0 Kg de fertilizante y 45 días de corte) con promedio de 28.25 macollas, presento el mayor valor para esta variable; el menor valor fue para el Tratamiento 6 (52 Gy, 0 Kg de fertilizante y 45 días de corte) con 24.5. Con respecto al ancho de hoja, se puede apreciar que el tratamiento 8 (52 Gy, 250 Kg de fertilizante y 45 días de corte) alcanzó el mayor ancho de la hoja con un valor de 2,07 cm, el menor valor correspondió al tratamiento 1 (0 Gy, 0 Kg de fertilizante y 35 días de corte) con un valor de 1,34 cm. En el análisis de la variable % RMS, se destacó el tratamiento 8 (0 Gy, 250 Kg de fertilizante y 45 días de corte) con 33.60 % y el menor valor lo representa el tratamiento 5 (52 Gy, 0 Kg de fertilizante y 35 días de corte) con 23.20 %. | es_ES |
