Resumen
La presente investigación se la realizó en el recinto San José de Las Peñas” del cantón Rocafuerte, localizada geográficamente a 01°02’08’’ de Latitud Sur, y a 80° 27’02” de Longitud Oeste, con una altitud de 13 msnm según datos de la Estación Meteorológica de Portoviejo, la cual presentó como objetivo general el evaluar la aplicación de fertilizantes foliares en la productividad del cultivo del frejol blanco (Phaseolus vulgaris L.) INIAP 463 y para ello se utilizaron diferentes fertilizantes con sus dosis (Vigorplant + 5cc y 10 cc; Seaweed extract + 5 y 10 cc; BiolSuper5 +15 y 30 cc; Evergreen Fertilizante sintético + 2.55 y 5 cc por litro de agua y un testigo absoluto sin aplicaciones) y se utilizó un diseño estadístico de Bloques completamente al Azar (DBCA), con 9 tratamientos y cuatro repeticiones, registrando un total de 36 unidades experimentales.
Donde los resultados, indicaron, que en la altura de planta la aplicación de Evergreen en dosis de 2.55 cc por litro de agua registró el mayor valor a los 20 y 30 días con 16.78 y 20.77cm. Mientras que a los 50 días fue para Seaweed Extract en dosis de 10 cc y Biol Súper 5 en dosis de 15 cc por litro de agua con 27.96 cm de altura de planta. En tanto que el número de vainas por planta Evergreen en dosis de 2.55 cc por litro de agua el mejor valor con 26 vainas promedio por planta, y en la longitud de vainas el Biol Súper 5 en dosis de 30cc por litro de agua el de mayor valor con 22 cm de longitud de vaina.
Para el número de granos por vaina las aplicaciones de Seaweed Extract 10 cc por litro de agua reportó 18.05 granos por vaina, y en el peso de 1000 granos Seaweed Extract en dosis de 5 cc por litro de agua produjo el mayor peso con 195.75 gramos en 1000 semillas y el mayor rendimiento por hectárea (kg), fue para el tratamiento Seaweed Extract en dosis de 5 cc que reportó la mayor producción de grano con 1873.75 kg por hectárea.
En tanto que el Cálculo de Presupuesto Parcial identificó que la utilización del fertilizante Biol Súper 5 en dosis de 15 cc por litro de agua, una Tasa de Retorno Marginal de 4.507,14%, siendo el fertilizante foliar recomendado.
The present investigation was carried out it in the enclosure San José of The Rocks" of the canton Rocafuerte, located geographically at 01°02'08 '' of South Latitude, and at 80° 27'02" of Longitude West, with an altitude of 13 msnm according to data of the Meteorological Station of Portoviejo, which presented as general objective evaluating the application of fertilizers foliares in the productivity of the cultivation of the white frejol (Phaseolus vulgaris L.) INIAP 463 and for they were used it different fertilizers with its doses (Vigorplant + 5cc and 10 cc; Seaweed extract + 5 and 10 cc; BiolSuper5 +15 and 30 cc; Evergreen synthetic Fertilizer + 2.55 and 5 cc for liter of water and an absolute witness without applications) and a statistical design of Blocks was used totally at random (DBCA), with 9 treatments and four repetitions, registering a total of 36 experimental units. Where the results, indicated that in the plant height the application of Evergreen in dose of 2.55 cc for liter of water registered the biggest value to the 20 and 30 days with 16.78 and 20.77cm. while to the 50 days it was for Seaweed Extract in dose of 10 cc and Biol Súper 5 in dose of 15 cc for liter of water with 27.96 cm of plant height. As long as the number of sheaths for plant Evergreen in dose of 2.55 cc for liter of water the best value with 26 sheaths average for plant, and in the longitude of sheaths the Biol Súper 5 in dose of 30cc for liter of water that of more value with 22 cm of sheath longitude. For the number of grains for sheath the applications of Seaweed Extract 10 cc for liter of water reported 18.05 grains for sheath, and in the weight of 1000 grains Seaweed Extract in dose of 5 cc for liter of water produced the biggest weight with 195.75 grams in 1000 seeds and the biggest yield for hectare (kg), it was for the treatment Seaweed Extract in dose of 5 cc that reported the biggest grain production with 1873.75 kg for hectare. As long as the Calculation of Budget Partially identified that the use of the fertilizer Biol Súper 5 in dose of 15 cc for liter of water, it presented a Rate of Marginal Return of 4.507,14%, being the fertilizer to foliate recommended
