Item Evaluación nitrógeno del efecto del complementario fraccionamiento en el del rendimiento y contenido de proteína del grano y validación de fungicidas y épocas de aplicación para el control de enfermedades en cebada cervecera (Hordeum vulgare L) en el Laguacoto III, cantón Guaranda(Universidad Estatal de Bolívar . Facultad de Ciencias Agropecuarias . Escuela de Ingeniería Agronómica, 2014) Chicaiza Chicaiza, Kleber Fabián; Monar, CarlosThe barley crop is the fourth most cultivated cereal in the world. The average yield in Ecuador is just 0.6 MT / ha, being the lowest figure at South America. Currently about 25,000 MT annually imported for industrial processing. This trial was conducted in the UEB Laguacoto III at an altitude of 2640 m with a rainfall during the growing cycle of 451.51 mm. Design of randomized complete blocks with three replications. In the essay I Nitrogen four doses of N were evaluated, 0 kg N / ha; 75 kg N / ha; 100 kg N / ha and 125 kg N / ha applied at tillering (Z22); and the appearance of the nodes on the main stem (Z30). Three types of fungicides and two varieties of barley are also evaluated. Analysis of variance, correlation, linear regression and Tukey test at 5% were performed to compare the means of the main factors and their interaction. This research summarizes the increased productivity of the crop of malting barley for the agro-ecological zone is the Scarlet Laguacoto variety with a dose of 125 kg / ha of N applied at two stages (tillering and stem elongation). Economically fungicide use is recommended because of the low incidence and severity of rust in this agro-ecological zone. Finally this study improved the productivity of barley with potential returns on 3 MT / ha
