Resumen
La presente investigación se realizó en el 2017 en la Granja Experimental
Vainillo de la Facultad de Ciencias Agrarias de la Universidad de Guayaquil,
ubicada en la vía Durán-Tambo, El Triunfo, provincia del Guayas. El estudio se
realizó en un área de 660 m2 seleccionada de un cultivo establecido de un año y
los objetivos que se plantearon fueron: 1) Generar alternativas de nutrición vegetal
para mejorar la productividad y rentabilidad en el cultivo de plátano (Musa AAB.)
variedad Dominico, en la zona de El Triunfo, provincia del Guayas. 2) Determinar
la mejor solución nutritiva a inyectarse en drench. 3) Determinar el efecto de la
aplicación de sustancias nutritivas más Leonardita sobre las características
agronómicas del cultivo. 4) Realizar el análisis económico de los tratamientos. Se
utilizó el diseño de bloques completamente al azar con arreglo factorial (2 x 2 x 2),
con cuatro repeticiones, la comparación de medias de tratamientos se la efectuó
mediante la prueba de Tukey (α 0,05) teniendo como conclusiones: Se determinó
de acuerdo a los datos revisados con respecto a la investigación planteada
podemos observar que la variable número de hojas inicial, número de hojas final,
perímetro, numero de manos y peso de racimos en la inyección soluciones
nutritivas aplicaciones con Leonardita mas urea (tratamiento 3) alcanzaron los
mejores rendimientos. De acuerdo a lo expuesto se analizó que la aplicación
mejoró las características agronómicas del cultivo el cual se pudo observar con
respecto al testigo en el racimo de cada planta siendo más grandes y rendimientos
acordes a la investigación. Con respecto al análisis económico el tratamiento tres
(Leonardita - urea) fue el más rentable con una tasa de retorno marginal de 524
%.
The present investigation was carried out in 2017 in the Experimental Farm Vanilla of the Faculty of Agrarian Sciences of the University of Guayaquil, located in Durán-Tambo road, El Triunfo, province of Guayas. The study performed in an area of 660 m2 selected from a one-year established crop and The objectives were: 1) Generate plant nutrition alternatives to improve productivity and profitability in the cultivation of plantain (Musa AAB.) Dominico variety, in the area of El Triunfo, province of Guayas. 2) Determine the best nutritious solution to inject in drench. 3) Determine the effect of application of nutrients plus Leonardite on the characteristics agronomic of the crop. 4) Carry out the economic analysis of the treatments. HE used the completely random block design with factorial arrangement (2 x 2 x 2), with four repetitions, the comparison of treatment means was made by means of the Tukey test (α 0,05) having as conclusions: It was determined according to the data reviewed with respect to the proposed investigation we can see that the variable number of initial sheets, number of final sheets, perimeter, number of hands and weight of bunches in the injection solutions nutritive applications with Leonardite plus urea (treatment 3) reached the better yields According to the above, it was analyzed that the application improved the agronomic characteristics of the crop which could be observed with respect to the witness in the cluster of each plant being larger and yields chords to the investigation. With respect to economic analysis, treatment three (Leonardite - urea) was the most profitable with a marginal rate of return of 524 %.
