dc.descriptionThis research work was carried out on the land of the "Rancho Alegre" farm located at km 1.5 of the Ventanas - Echeandía road, Los Ríos province. in the geographical coordinates1 01 ° 26ʹ29.8ʺ S; 79 ° 25ʹ5.7ʺ W and 12 masl. The annual average of precipitation is 2329.8 mm; 80% relative humidity; 998.2 hours of heliophany and a temperature of 25.0 ° C. EMBLEMA corn hybrid material was used as planting material, which is more adapted to the area. The treatments consisted of the different levels of the foliar fertilizer Gibberellic acid + Indol-3-ylacetic acid + Brassinolide, in doses of 10, 20, 30 and 40 g / ha; plus a control treatment without application. The Randomized Complete Blocks experimental design with five treatments and 4 repetitions was used, the significance test used was Tukey's 95% probability. All necessary agricultural work was carried out in the cultivation of corn for its normal development, such as soil preparation, planting, irrigation, fertilization, weed control, phytosanitary control and harvesting. To estimate the effects of the treatments, the following data were taken: plant height, ear insertion height, ear length, number of grains per ear, number of rows of grain per ear, weight of 100 seeds, yield, analysis economic. Based on the results obtained, it was determined that the foliar fertilizer based on brassinosteroids applied in the T2 treatment with a dose of 20 g / ha, showed the highest averages in the variables number of grains per ear, number of rows per ear, weight of 100 seeds (g) and yield (kg / ha). Regarding the variables plant height (m) and ear length (cm), treatment 4 in a dose of 40 g / ha (GIB + INDOL + BRASSI), showed the highest averages with 2.58 and 20.35 cm respectively for these variables. There were no significant differences for the treatments applied in the variables: insertion height from ear to ear. As for the economic analysis, the greatest net benefit was obtained by treatment 2 in a dose of 20 g / ha (GIB + INDOL + BRASSI) with $ 1,303.58.es_ES

dc.description.abstractEl presente trabajo de investigación se desarrolló en los terrenos de en la finca “Rancho Alegre” ubicada en el km 1,5 de la vía Ventanas - Echeandía, provincia de Los Ríos. en las coordenadas geográficas1 01°26ʹ29,8ʺ S; 79°25ʹ5,7ʺ W y 12 msnm. El promedio anual de precipitación es de 2329,8 mm; 80% de humedad relativa; 998.2 horas de heliofanía y temperatura de 25.0 °C. Como material de siembra se utilizó el material hibrido de maíz EMBLEMA, que está más adaptada a la zona. Los tratamientos estuvieron constituidos por los diferentes niveles del fertilizante foliar Gibberellic acid + Indol-3-ylacetic acid + Brassinolide, en dosis de 10, 20, 30 y 40 g/ha; más un tratamiento testigo sin aplicación. Se empleó el diseño experimental Bloques Completos al Azar con cinco tratamientos y 4 repeticiones, la prueba de significancia utilizada fue de Tukey al 95 % de probabilidad. Se realizaron todas las labores agrícolas necesarias en el cultivo de maíz para su normal desarrollo como preparación de suelo, siembra, riego, fertilización, control de malezas, control fitosanitario y cosecha. Para estimar los efectos de los tratamientos, se tomaron los siguientes datos: altura de planta, altura de inserción de mazorca, longitud de mazorca, número de granos por mazorca, número de hileras de grano por mazorca, peso de 100 semillas, rendimiento, análisis económico. Por los resultados obtenidos se determinó que el fertilizante foliar en base a brasinoesteroides aplicados en el tratamiento T2 con dosis de 20 g/ha, mostro los mayores promedios en las variables número de granos por mazorca, numero de hileras por mazorca, peso de 100 semillas (g) y rendimiento (kg/ha). Con respecto a las variables altura de planta (m) y longitud de la mazorca (cm) el tratamiento 4 en dosis de 40 g/ha (GIB + INDOL + BRASSI), mostro los mayores promedios con 2.58 y 20.35 cm respectivamente para estas variables. No existió diferencias significativas para los tratamientos aplicados en las variables: altura de inserción de mazorca por mazorca. En cuanto al análisis económico, el mayor beneficio neto lo obtuvo el tratamiento 2 en dosis de 20 g/ha (GIB + INDOL + BRASSI) con $ 1,303.58.es_ES
