Resumen
La presente investigación se realizó finalizando la época seca del 2017 y a
inicios de la época lluviosa del 2018 en la Granja Experimental “Vainillo” de
la Facultad de Ciencias Agrarias de la Universidad de Guayaquil, con sus
coordenadas geográficas son Latitud Sur 02°20’22”; Longitud oeste
79°31’43”, Altitud 35 msnm; dicho trabajo de campo duro 2,6 meses, en el
mismo se evaluó fosfito de potasio a diferentes dosis y formas de aplicación.
Se empleó un diseño de bloques completamente al azar (DBCA) con 10
tratamientos y 4 repeticiones. Con la aplicación de fosfito de potasio en
concentración de 1000 cc/ha, hay un incremento del 41% en la producción
con un rendimiento de fruto fresco de 39418 kilos por hectárea, con el
tratamiento F+D x A2 (foliar más drench a razón de 1000cc/ha), dando por
ende la mejor utilidad de $ 4101.90, lo mismo que genero una relación
beneficio/costo igual a $2.37.
The present research was carried out at the end of the dry season of 2017 and beginning of the rainy season of 2018 in the experimental Farm "Vainillo", which is property of the Agrarian Sciences faculty of the University of Guayaquil. The geographical coordinates are South latitude 02 ° 20'22 "; West longitude 79 ° 31'43 ", and altitude 35 mas. The present field work lasted 2,6 months, in which potassium phosphite was evaluated at different doses and application forms. A full y randomized block design (DBCA) with 10 treatments and 4 replications was used. With the application of potassium phosphite in a concentration of 1000 cc / ha, there is a 41% increase in the production with a fresh fruit yield of 39418 kilos per hectare, with the F + D x A2 treatment (foliar plus drench to ratio 1000cc / ha), giving therefore the best utility of $ 4101.90, the same that generated a benefit / cost ratio equal to $ 2.37.
