Resumen
El presente trabajo de investigación se realizó durante la época seca de
2015 en la Granja Experimental “Vainillo” perteneciente a la Facultad de
Ciencias Agrarias de la Universidad de Guayaquil, ubicada en el km 48 vía
al Triunfo, provincia del Guayas.
Los objetivos fueron los siguientes: Evaluar los métodos aplicación de
fertilizantes con base de N, P, K, en una variedad de fréjol arbustivo,
Determinar los niveles de aplicación de fertilizantes con base de N, P, K,
Evaluar el rendimiento del fréjol en la zona en estudio y Realizar un análisis económico de los tratamientos.
Los tratamientos evaluados fueron los siguientes: Dos formas de aplicación
de fertilizantes con base N, P, K disuelto y granulado en forma edáfica. Con
un diseño de bloques al azar (DBCA) en arreglo factorial (3 x 2) con cuatro
repeticiones.
Las variables evaluadas fueron las siguientes: días a floración, días a la
maduración, altura de planta, altura de carga, vainas/planta, semillas/planta,
semillas/vaina, peso de 100 granos (g), Rendimiento (kg/ha) y el análisis
económico.
De acuerdo a los resultados obtenidos se concluye: a) La evaluación de los
métodos de aplicación de fertilizantes con base de N,P,K fue en forma
granulada en el cultivo de fréjol b) En la determinación de los niveles de
aplicación de los fertilizantes N-P (D.A.P.) (F2) y N-P-K (8-20-20) (F3)

The present research was conducted during the dry season of 2015 in the Experimental Farm "Vainillo" belonging to the Faculty of Agricultural Sciences of the University of Guayaquil, located at km 48 on the way to El Triunfo, Guayas province. The objectives were as follows: To evaluate the methods of fertilizers application with basic compounds of N, P, K, in a variety of bushy beans, determine the levels of fertilizers application with basic compounds of P, K, evaluate the yield of the bean plants in the study area and an economic analysis of treatments. The evaluated treatments were as follows: Two forms of fertilizers application based on N, P, K dissolved and granulated in form of soil. With a randomized block design (RCBD) in accordance with a factorial (3 x 2) with four replications. The evaluated variables were as follows: days to flowering, days to maturity, plant height, loading height, pods / plant, seeds / plant, seeds / pod, weight of 100 grains (g), grain yield (kg / ha) and the economic analysis. According to the results it is concluded that : a) The evaluation of the application methods of fertilizers based on N, P, K was in granulated form for the most part of the cultivation of beans b) In the determination of the levels of implementation of the N-P fertilizers (DAP) (F2) and NPK (8-20-
