Resumen
Esta investigación se realizó durante la época seca del año 2013 y parte de la época lluviosa de 2014, en la granja experimental “Vainillo” de la Facultad de Ciencias Agrarias de la Universidad de Guayaquil, ubicada en la vía Durán-Tambo, cantón El Triunfo de la provincia del Guayas.
Como objetivo general se planteó desarrollar nuevas tecnologías sobre nutrición, para mejorar la calidad y productividad del cultivo de arroz. Los objetivos específicos fueron los siguientes: 1) determinar la dosis óptima de Leonardita sobre las características agronómicas en el cultivo de arroz. 2) Realizar un análisis económico de los tratamientos para medir la factibilidad de esta tecnología.
Los factores estudiados fueron dosis de aplicación de nitrógeno, niveles de Leonardita (0, 2000, 4000, 6000 y 8000 g/ha), en combinación con fertilización nitrogenada.
Se utilizó el diseño de bloques completamente al azar con arreglo factorial 5 x 2 (DBCA-AF), con tres repeticiones.
This research was conducted during the dry season of 2013 and 2014 rainy part of the experimental farm "Vainillo" of the Faculty of Agricultural Sciences at the University of Guayaquil located in Via dairy during the Triunfo Guayas province. As a general objective to develop new technologies to improve nutritional quality and productivity of rice. The specific objectives. 1) Determine the optimal dose of Leonardita, macro and micro elements on agronomic traits in rice. 2) Perform an economic analysis of treatments to measure the feasibility of this technology. The factors studied were Nitrogen application rates in combination with Leonardita. 0 – 2000 – 4000 – 6000 – 8000 g with Leonardita in combination with nitrogen fertilization. One block completely randomized design with factorial arrangement (DBCA-AF) 5 x 2 with three replications. Seven agronomic variables were measured and partial budget analysis was performed in order to measure the economic feasibility of using this product. He concluded: a) the highest number of panicles/m2 was within the range of treatments 0-4000 kg of Leonardita/ha. b) Less empty was obtained with the application of 160 kg N/ha. c) With 160 kg/ha and adding Leonardita
