Efecto de la aplicación de cinco dosis de Leonardita en combinación con dos niveles de nitrógeno en arroz oriza sativa
Abstract:
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
