Resumen
La presente investigación se realizó en un invernadero ubicado en la provincia del Guayas, cantón Milagro, recinto “Los Monos”, a 15 msnm. Con coordenadas de 79° 41′ 69′′ de longitud oeste y 02° 05′ 80′′ de latitud sur. Se la realizó en época seca. Los objetivos fueron: a) Determinar agronómicamente el híbrido que mejor se adapte al sistema hidropónico. b) Determinar la mejor combinación de sustrato para la siembra. c) Realizar un análisis económico de los tratamientos.
Se realizó la investigación con dos híbridos de zucchini y cuatro sustratos con base de Zeolita 50% + Cascarilla de arroz 50%, Suelos 50% + cascarilla de arroz 50%, arena 50% + cascarilla de arroz 50%, Arena % + Cascarilla 50% y suelo 100%, bajo un sistema de cultivo hidropónico, cuyas combinaciones resultaron en ocho tratamientos, se utilizó el diseño de bloques completamente al azar (DBCA) con arreglo factorial 2 x 4, con cuatro repeticiones. Para la comparación de las medias de tratamientos se utilizó la prueba de rangos múltiples de Duncan con el 5% de probabilidad. Se estudiaron en total nueve variables.
Se concluyó: a) El híbrido Ortolana Di Faenza con el sustrato uno (Zeolita 50% + cascarilla 50%) fue el que presentó un mayor rendimiento de peso de frutos; b) Los dos híbridos de zucchini fueron iguales en rendimiento de peso de frutos; c) La mezcla de sustratos de 50 % de zeolita y 50 % de cascarilla de arroz, respondió favorablemente en el manejo del cultivo y d) La mejor Tasa Marginal de Retorno (TMR) la
This research was conducted in a greenhouse located in the province of Guayas, Canton Milagro, enclosure "Monkeys", a 15 m.s.n.m., With coordinates 79 ° 41 '69' 'west longitude and 02 ° 05' 80 '' south latitude. She was held in the dry season. The objectives were: a) Determine agronomically hybrid best suited to hydroponic system. b) To determine the best combination of substrate for planting. c) Perform an economic analysis of the treatments. The research was conducted with two hybrids zucchini and four substrates based Zeolite 50% + rice husk 50%, soil 50% + rice husk, 50% sand + 50% rice husk, and soil 100%, under a hydroponics system, which resulted in eight treatments combinations, block design was used totally at random (DBCA) 2 x 4 factorial arrangement, with four replications. The multiple range test of Duncan was used with a 5% chance to compare treatment means nine variables were studied in total. He concluded: a) The hybrid Ortolana Di Faenza with the substrate one (50% Zeolite + 50% rice husk) was the one that presented a higher yield of fruit weight; b) The two hybrids were equal in performance zucchini weight of fruit; c) The mixture of substrates of 50% zeolite and 50% rice husk, responded favorably crop management d) Marginal Best Rate of Return (TMR) introduced the interaction H2-S2 (Nano Verde di Milano - 50% soils + 50% rice husk).
