| dc.description | This experimental work was carried out on the grounds of the Experimental Farm "San Pablo" of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at Km 7 ½ of the Babahoyo - Montalvo road. The genetic material used was the Savoy grass that is found planted in the facilities of the Faculty of Agricultural Sciences of the Technical University Babahoyo. Nitrogen and Calcium-based treatments were evaluated, such as Nitrogen + Calcium in doses of 150 kg / ha of N + 2.0 L CaO and 100 kg / ha of N + 1.0 L CaO; Nitrogen in a dose of 100 kg / ha of N; Calcium in 1.0 L CaO dose and an absolute control. The applications of the treatments were made 30, 60 and 90 days after the start of the trial, according to each of the established cuts. The experimental design was Completely Random Blocks with five treatments and four repetitions, using the Tukey test at 95% probability. Based on the results, it was determined that the fertilization with Nitrogen and Calcium caused favorable effects in the biomass increase of the saboya grass irradiated to 52 Gy, in the Babahoyo area; the application of nitrogen in doses of 100 kg / ha influenced so that there is a higher plant height at 30 and 60 days after the first cut, decreasing at 90 days, where the use of calcium in doses of 1.0 L / stood out he has; the numbers of tillers per plant at 30, 60 and 90 days after the first cut, obtained better averages with the use of Calcium at a dose of 1.0 L / ha; the number of leaves per bunch fluctuated between 4 and 6 leaves in the treatments studied; Applying Nitrogen in doses of 100 kg / ha at 30 and 60 days after the first cut and Nitrogen + Calcium in doses of 150 kg / ha of N + 2.0 L CaO, at 90 days after the first cut promoted the highest leaf width; the leaf length presented higher averages at 30, 60 and 90 days after the first cut using Calcium at a dose of 1.0 L / ha; the highest leaf area index, chlorophyll percentage, fresh weight and dry weight, at 30, 60 and 90 days after the first cut, reported higher averages using Nitrogen at a dose of 100 kg / ha and in the economic analysis it was reflected that The greatest net benefit was achieved by the treatment with nitrogen applied in doses of 100 kg / ha with a net benefit of $ 377.24. | es_ES |

| dc.description.abstract | El presente trabajo experimental se realizó en los terrenos de la Granja Experimental “San Pablo” de la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Babahoyo, ubicada en el Km 7 ½ de la vía Babahoyo – Montalvo. El material genético que se utilizó el pasto Saboya que se encuentra sembrado en las instalaciones de la Facultad de Ciencias Agropecuarias de la Universidad Técnica Babahoyo. Se evaluaron los tratamientos a base de Nitrógeno y Calcio, tales como Nitrógeno + Calcio en dosis de 150 kg/ha de N + 2,0 L CaO y 100 kg/ha de N + 1,0 L CaO; Nitrógeno en dosis de 100 kg/ha de N; Calcio en dosis de 1,0 L CaO y un testigo absoluto. Las aplicaciones de los tratamientos se realizaron a los 30, 60 y 90 días de iniciado el ensayo, conforme cada uno de los cortes establecidos. El diseño experimental fue de Bloques Completamente al Azar con cinco tratamientos y cuatro repeticiones, utilizando la prueba de Tukey al 95 % de probabilidad. Por los resultados se determinó que la fertilización con Nitrógeno y Calcio, causó efectos favorables en el incremento de biomasa del pasto saboya irradiado a 52 Gy, en la zona de Babahoyo; la aplicación de nitrógeno en dosis de 100 kg/ha influyó para que exista mayor altura de planta a los 30 y 60 días después del primero corte, decreciendo a los 90 días, donde sobresalió el uso de calcio en dosis de 1,0 L/ha; los número de macollos por planta a los 30, 60 y 90 días después del primero corte, obtuvieron mejores promedios con el empleo de Calcio en dosis de 1,0 L/ha; el número de hojas por macollo fluctuó entre 4 y 6 hojas en los tratamientos estudiados; aplicando Nitrógeno en dosis de 100 kg/ha a los 30 y 60 días después del primer corte y Nitrógeno + Calcio en dosis de 150 kg/ha de N + 2,0 L CaO, a los 90 días después del primer corte promovió el mayor ancho de la hoja; el largo de la hoja presentó mayores promedios a los 30, 60 y 90 días después del primer corte utilizando Calcio en dosis de 1,0 L/ha; el mayor índice de área foliar, porcentaje de clorofila, peso fresco y peso seco, a los 30, 60 y 90 días después del primer corte, reportó mayores promedios empleando Nitrógeno en dosis de 100 kg/ha y en el análisis económico se reflejó que el mayor beneficio neto lo alcanzó el tratamiento que se aplicó Nitrógeno en dosis de 100 kg/ha con un beneficio neto de $ 377,24. | es_ES |
