Resumen
El presente trabajo se llevó a cabo en el cantón Daule, provincia del
Guayas, en el periodo comprendido entre los meses de marzo del 2016a
julio del 2016, esta investigación se realizó con la finalidad de establecer
una nueva alternativa, cuyo objetivo fue: Contribuir al mejoramiento
tecnológico de la fertilización con productos orgánicos y la aplicación de
una hormona AG3, en una dosis de 0.5 mg/L cuando la planta estuvo en
pleno crecimiento activo. En el ensayo se emplearon semillas de sandía
(Citrullus lanatus), variedad AnguriaCharleston graydistribuida por la
empresa Galassi Sementi, adquiridas en laprovincia del Guayas, el
áreaexperimental estuvo constituida por cincotratamientos y cinco
repeticiones los que hacían un total de 25 tratamientos cada uno con 10
plantas. Para el análisis estadístico se utilizó el diseño completamente al
azar, y para la comparación de las medias el SAS (Sistema de Análisis
Estadístico) los tratamientosfueron evaluados a los 20, 40 y 60 ddt (días
después del trasplante), en cuanto a fertilización las aplicaciones de los
productos orgánicos se realizaron a los ocho, quince, treinta y cuarenta y
cinco días durante el desarrollo del cultivo, a dichos tratamientos se les
aplicó el AG3 en una sola dosis de 0,5mg/L en el trasplante, floración y
cuajado de los frutos;las dosis aplicadas de los productos orgánicos
fueron: De Calcio complejado en dosis de 2 hasta 5 L/Ha, Acido
Carboxílico en dosis de 250-500-750gr y de 1/Ha, NP con Aminoácidos
en dosis de 500-750gr y de 1 – 1.5 L/Ha, Aminoácidos con
Micronutrientes en dosis de 500 – 750gr y de 1 – 1.5 – 2 L/Ha, y un testigo
con siembra tradicional, una vez terminado el experimento, se tomaron
cinco plantas al azar en el área útil, y se les evaluó las respectivas
variables como fueron: Longitud de guía, número de frutos por planta,
diámetro del fruto, longitud del fruto, peso de fruto, grosor de la corteza
The present project was carried out in the canton Daule, Guayas province, in the period from March to June 2016, this research was conducted in order to establish a new alternative, whose main aim was to contribute to technological improvement of fertilization with organic products and the application of a hormone GA3, at a dose of 0.5 mg / L when the plant was in full active growth. On the other hand, seeds of watermelon (Citrullus lanatus), variety Anguria Charleston gray distributed by the company Galassi Sementi, acquired in the province of Guayas were used in this experiment, the experimental area consisted of five treatments and five repetitions whit a total of 25 treatments with 10 floors each. For statistical analysis a complete randomized design was used, and for the comparison of the means, the SAS (Statistical Analysis System) treatments were evaluated at 20, 40 and 60 days after transplantation. Regarding fertilization, applications of organic products were performed at eight, fifteen, thirty to forty-five days during the crop development, it was applied GA3 in one dose of 0.5mg / L to these treatments during the transplantation, bloom and fruit soured; applied doses of organic products were performed: Calcium dose complexed in L 2-5 / Ha, at doses Carboxylic Acid 250-500-750gr and 1 / Ha, NP amino acids in doses of 1 and 500-750gr - 1.5 L / Ha, Amino Acids and Micronutrient in doses of 500 - 750gr and 1 - 1.5 - 2 L / Ha, and a witness with traditional sowing, once the experiment has ended, five plants were randomly chosen in the useful area, and they were evaluated according to the respective variables with the following result: length guide, number of fruits per plant, fruit diameter, fruit length, fruit weight, thickness of fruit rind, rind color and flesh color. Then the data collected was analyzed and tabulated. Based on all this research work, the conclusion in general terms was that the
