dc.descriptionThis experimental work was carried out in the "Javilla" Campus, owned by Mr. Rober Lagos Briones, located on the Pan-American highway, Km. 41, entering through the banana plantation "La Envidia", with the geographical coordinates of 654794 UTM Latitud South, 9782451 West longitude and a height of 8 masl The rice seed variety Iniap FL 1480 "Cristalino" was used. The treatments that were used consisted of foliar and soil fertilizers with the respective doses, such as Calcium + Manganese + Potassium in doses of 1.0 L + 1.0 L + 100 kg and 1.0 L + 1.0 L + 150 kg / ha; Calcium + Manganese 1.0 L + 1.0 L; Calcium 1.0 L; Manganese 1.0 L; Potassium 100 kg and 150 kg / ha and an absolute Witness without fertilizer application. In the present trial, the experimental design "Complete random blocks" was used, with eight treatments and three repetitions, being evaluated with the Tukey test at 95% probability. Based on the results obtained, it was concluded that the application of Calcium and Manganese obtained a positive response in the preventive management of Pyricularia oryzae in rice cultivation, in the Jujan - Guayas area; the absolute control treatment, without the application of fertilizers, obtained a higher percentage of incidence and severity of P. Oryzae; in the evaluation carried out 30 days after transplantation, a higher average percentage of chlorophyll was obtained, decreasing at the time of flowering, due to the effect of the fertilizers applied in each of the treatments studied; the agronomic characteristics of plant height, tillers and panicles / m2 and panicle length, stood out with the use of Calcium + Manganese + Potassium, in doses of 1.0 L + 1.0 L + 150 kg; in the variables grain-straw ratio and percentage of empty grains, they did not report significant differences in their averages; the agronomic efficiency of the application of Calcium and Manganese, registered the application of Calcium + Manganese + Potassium, in doses of 1.0 L + 1.0 L + 150 kg influenced the efficiency of Calcium, while Manganese was for use Manganese alone, at a dose of 1.0 L / ha and the highest weight of 1000 grains, grain yield / ha and net benefit was achieved with the use of Calcium + Manganese + Potassium, at a dose of 1.0 L + 1 , 0 L + 150 kg, with 27.7 g; 5,463.7 kg / ha and $ 535.57.es_ES

dc.description.abstractEl presente trabajo experimental, se realizó en el Recinto "Javilla", de propiedad del Sr. Rober Lagos Briones, ubicados en la vía panamericana, Km. 41, entrando por la bananera “La Envidia”, con las coordenadas geográficas de 654794 UTM Latitud Sur, 9782451 Longitud Oeste y una altura de 8 m.s.m.n. Se empleó la semilla de arroz variedad Iniap FL 1480 "Cristalino". Los tratamientos que se utilizaron estuvieron constituidos por fertilizantes foliares y edáficos con las respectivas dosis, tales como Calcio + Manganeso + Potasio en dosis de 1,0 L + 1,0 L + 100 kg y 1,0 L + 1,0 L + 150 kg/ha; Calcio + Manganeso 1,0 L + 1,0 L; Calcio 1,0 L; Manganeso 1,0 L; Potasio 100 kg y 150 kg/ha y un Testigo absoluto sin aplicación de fertilizantes. En el presente ensayo se utilizó el diseño experimental "Bloques completos al azar", con ocho tratamientos y tres repeticiones, evaluándose con la prueba de Tukey al 95 % de probabilidad. Por los resultados obtenidos se concluyó que la aplicación de Calcio y Manganeso obtuvieron respuesta positiva en el manejo preventivo de Pyricularia oryzae en el cultivo de arroz, en la zona de Jujan – Guayas; el tratamiento de testigo absoluto, sin aplicación de fertilizantes, obtuvo mayor porcentaje de incidencia y severidad de P. Oryzae; en la evaluación efectuada a los 30 días después del trasplante se obtuvo mayor promedio de porcentaje de clorofila, disminuyéndose al momento de la floración, por efecto de los fertilizantes aplicados en cada uno de los tratamientos estudiados; las características agronómicas de altura de planta, macollos y panículas/m2 y longitud de panícula, sobresalieron con el uso de Calcio + Manganeso + Potasio, en dosis de 1,0 L + 1,0 L + 150 kg; en las variables relación grano-paja y porcentaje de granos vanos no reportaron diferencias significativas en sus promedios; la eficiencia agronómica de la aplicación de Calcio y Manganeso, registró la aplicación de Calcio + Manganeso + Potasio, en dosis de 1,0 L + 1,0 L + 150 kg influyó en la eficiencia de Calcio, mientras que Manganeso fue para el uso de Manganeso solo, en dosis de 1,0 L/ha y el mayor peso de 1000 granos, rendimiento de grano/ha y beneficio neto se consiguió con el uso de Calcio + Manganeso + Potasio, en dosis de 1,0 L + 1,0 L + 150 kg, con 27,7 g; 5463,7 kg/ha y $ 535,57.es_ES
