Arzube Alvarado, Sergio Javier
El presente trabajo se realizó en los terrenos de la finca Las Delicias ubicada en el cantón Simón Bolívar - Guayas. Para la siembra fue utilizado el híbrido de maíz “NS-70. El objetivo del trabajo fue evaluar la aplicación de diversas dosis de Calcio, Boro y Zinc en la producción de maíz. Para el efecto se emplearon los productos Sett y Keylate Zinc, en un diseño de “Bloque Completos al Azar” con tres repeticiones. La siembra del cultivo se realizó de forma manual en parcelas experimentales de 20 m2. El análisis de varianza estableció la significancia estadística y la evaluación de medias se hizo con la prueba de significancia de Tukey al 5 %. Las variables evaluadas al final del ensayo fueron: altura de planta, altura de inserción, días a floración, días a cosecha, diámetro de mazorcas, longitud de mazorcas, peso de grano, rendimiento por hectárea, productividad parcial por nutriente (PPN) y análisis económico. Los datos demuestran que las variables: altura de planta, altura de inserción, días a floración, días a cosecha, longitud de mazorcas, diámetro de mazorcas y número de granos, no alcanzaron significancia estadística. El peso de grano tuvo su mayor promedio aplicando Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha, Sett 1,0 l/ha + Keylate Zinc 0,5 l/ha y Sett 1,0 l/ha + Keylate Zinc 1,0 l/ha. El mayor de rendimiento de grano fue alcanzado aplicando Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha (8939,16 kg/ha). Los valores de productividad parcial por nutriente PPN fueron mayores para Calcio y Boro aplicando Sett 0,5 l/ha + Keylate Zinc 0,5 l/ha. Los valores de Zinc a diferencia fueron altos en las plantas tratadas con. Sett 1,0 l/ha + Keylate Zinc 0,5 l/ha. El tratamiento Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha presentó la mayor utilidad y beneficio Neto.
The present work was carried out on the land of the Las Delicias farm located in the Simón Bolívar - Guayas canton. For sowing, the corn hybrid “NS-70 was used. The objective of the work was to evaluate the application of various doses of Calcium, Boron and Zinc in the production of corn. For the effect, the Sett and Keylate Zinc products were used, in a “Random Complete Block” design with three repetitions. The sowing of the crop was carried out manually in experimental plots of 20 m2. The analysis of variance established the statistical significance and the evaluation of means was done with the Tukey significance test at 5 %. The variables evaluated at the end of the trial were: plant height, insertion height, days to flowering, days to harvest, diameter of ears, length of ears, grain weight, yield per hectare, partial productivity per nutrient (PPN) and analysis economic. The data show that the variables: plant height, insertion height, days to flowering, days to harvest, length of ears, diameter of ears and number of grains, did not reach statistical significance. The grain weight had its highest average applying Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha, Sett 1,0 l/ha + Keylate Zinc 0,5 l/ha and Sett 1,0 l/ha + Keylate Zinc 1,0 l/ha. The highest grain yield was achieved by applying Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha (8939,16 kg/ha). The partial productivity values per nutrient PPN were higher for Calcium and Boron applying Sett 0,5 l/ha + Keylate Zinc 0,5 l/ha. The Zinc values in contrast were high in the plants treated with. Sett 1,0 l/ha + Keylate Zinc 0,5 l/ha. The Sett 1,0 l/ha + Keylate Zinc 0,75 l/ha treatment presented the highest utility and net benefit.; The present work was carried out on the land of the Las Delicias farm located in the Simón Bolívar - Guayas canton.

El trabajo experimental se realizó en los terrenos de la finca “Don Luis “propiedad del Sr. Luis Duche, en el cantón Montalvo. Se buscó determinar el efecto del fertilizante Orgevit® en diferentes dosis y épocas de aplicación, contra un programa de fertilización química normal en el cultivo, en el cultivo. Como material vegetal se empleó el híbrido Cubanell. Con esto se evaluó los efectos de las dosis de los productos sobre el comportamiento agronómico y un análisis económico del rendimiento de fruto en función al costo de los tratamientos. Se utilizó el diseño experimental bloques completos al azar, con 8 tratamientos y tres repeticiones. Se evaluaron las variables: altura de planta, días a floración y maduración fisiológicas, numero de frutos por planta, longitud de frutos, diámetro de frutos, peso de frutos, rendimiento por hectárea y análisis económico. Las variables evaluadas fueron expuestas al análisis de varianza, y se aplicó la prueba de Tukey al 5% de significancia para determinar la diferencia estadística entre las medias de los tratamientos. Indicados los resultados experimentales se logró significancia estadística en todas las variables. El tratamiento Orgevit® 400 kg/ha aplicado a los 0-15-35 días después del trasplante, presento los mejores números en especial aquellos relacionados con el rendimiento de fruto y análisis económico.

La investigación fue realizada en los predios de la finca “Don Luis “propiedad del Sr. Luis Duche, recinto “Las Balsas”, en el cantón Montalvo, provincia de los Ríos. El material de siembra fue el híbrido de maíz “Emblema 777”, utilizando como tratamientos los fertilizantes edáficos Rafos y Nitrodoble, solos y en mezclas, comparándolos contra dos programas de fertilización convencional y un testigo sin aplicación, en tres repeticiones. El objetivo del trabajo fue evaluar el efecto de los programas en el rendimiento de grano. La siembra de maíz fue efectuada manualmente en unidades experimentales de 20 m2. Los tratamientos se distribuyeron en un diseño de bloques completos al azar DBCA. El análisis de varianza estableció la significancia estadística y en la evaluación de medias se empleó la prueba de significancia de Tukey al 95 %. Las variables valoradas fueron: altura de planta, altura de inserción, días a floración, días a cosecha, diámetro de mazorcas, longitud de mazorcas, peso de grano, rendimiento por hectárea, eficiencia agronómica y análisis económico. Los resultados encontrados establecen que todos los tratamientos fertilizados sobrepasaron al testigo sin aplicación de fertilizantes. Los tratamientos fertilizados presentaron paridad estadística en varias variables con excepción de días a la floración, días a maduración fisiológica y peso de grano. El tratamiento Rafos 350 kg/ha + Nitrodoble 120 kg/ha de alcanzo mayor rendimiento de grano. La mayor tasa de eficiencia agronómica se cálculo en el tratamiento Rafos 250 kg/ha + Nitrodoble 120 kg/ha, siendo en fósforo el testigo químico y potasio Rafos 250 kg/ha + Nitrodoble 120 kg/ha. Económicamente todos los tratamientos fueron mayores al testigo. El tratamiento Raphos + Nitrodoble (350 +120 kg/ha) generó la mayor utilidad.

El objetivo de esta investigación fue evaluar la digestibilidad in vitro de la panca de arroz tratada con urea. Se utilizo Panca de arroz sin amonificar1kg, fundas de polietileno y balanza gramera. Para este estudió se utilizó un diseño completamente al azar con arreglo bifactorial de 2x3. Para la evaluación de medias se utilizó la prueba de Tukey al 5%. Se evaluaron la digestibilidad in vitro de la panca de arroz tratada con urea y sin urea. Aplicando el método de comparación de media Tukey al 5% se pudo comprobar que existió diferencia entre las medias de los tratamientos. Los resultados obtenidos fueron: en el primer factor, la panca de arroz amonificada alcanzó un promedio de 48,84%. En el segundo factor, la fracción tallo alcanzó el mejor promedio con 48,31%. En la interacción el mejor tratamiento fue la panca amonificada con fracción tallo con 52,96% y el menor valor lo registra la panca de arroz sin amonificar con fracción hojas con una digestibilidad in vitro de 38,88%. En el primer factor, la panca de arroz amonificada alcanzó un promedio de 48,25%. En el segundo factor, la fracción tallo alcanzó el mejor promedio con 47,38%.
