    La aplicación de técnicas alternativas limpias en el control de trips (Frankliniella tuberosi) en el cultivo de papa (Solanum tuberosum var. Super chola), en la Granja Victoria
    (2017) Toro Álava, Marco Patricio; Pomboza Tamaquiza, Pedro Pablo
    The purpose of this research work is the generation of a proposal on the control of Clean Way in the Handling of Pests of a special way of thrips in the cultivation of potato. At the provincial level has worked on the implementation of a Clean Production, and this is the way to give the consumer a guarantee, through programs of agricultural specialization given by the Provincial Government of Tungurahua under the Agricultural Strategy, with a production approach Clean For the reduction of agro-toxic inputs. This proposal was generated through visits to potato producers who have entered into certification processes with UCALT, and their need for other alternatives to chemicals. This work is considered important because it will be possible to optimize the knowledge presented in this proposal. Although the use of this method of control by plant extracts is to avoid the use of insecticides and thus avoid the poisoning of humans, since they do not produce health effects, because the plants from which these active ingredients are extracted , Do not have any kind of counterproductive effect in humans. The intervention with plant extracts, still not widely used, but his investigations are increasing with positive results. So the advantages of this proposal would be: Produce with natural techniques, without causing environmental damage, control naturally, preserving the health of the ecosystem.

    Validación de una estrategia en el control de tizón tardío (Phytophthora infestans) en papa (Solanum tuberosum L.) con las variedades INIAP-libertad, INIAP-cecilia y superchola, en la provincia de Tungurahua
    (2017) Freire Tenelema, Mayra Alejandra; Cruz Tobar, Saúl Eduardo
    The following investigation seeks to validate one strategy to control Late Blight (phytophthora infestans) in potatoes (solanum tuberosum l.) in three potato types, INIAP Cecilia, Superchola, Libertad with the aid of the DSS (Decision Support System) through a frequency of application and evaluation of 8-12-15 days to ob-tain the best control strategy to cause less environmental impact. By doing the statistical analysis of the area under the disease progress curve (AUDPC) it was possible to determine that the potato type Libertad, due to its own characteristics, showed a higher resistance to Late Blight compared to the other potato types. Regarding the Environmental Impact Rating we could determine an important de-crease when applying the DSS compared to the Farmer treatment, which shows, in the case of the Cecilia potato type, a reduction of 85,89%, in Libertad potato type 97,82% and in Super chola potato type 88,87%.

    Análisis del sistema de uso de la tierra y condiciones de vida a nivel comunitario en poblaciones kichwas de la reserva de biosfera Sumaco Región Amazónica Ecuatoriana
    (2013-11-07) Sarabia Guevara, Danilo; Cruz Tobar, Eduardo
    El propósito de este trabajo de investigación es caracterizar las condiciones de vida a nivel comunitario de las poblaciones Kichwas de la Reserva de Biosfera Sumaco de la Región Amazónica Ecuatoriana, para lograr este objetivo se aplicó el Cuestionario PEN RAVA para Comunidad, adaptando a las condiciones del estudio, para el procesamiento de la información se aplicó el paquete estadístico STATGRAPHICS Centurión. El presente trabajo investigativo describó algunos elementos de la realidad socioeconómica de las comunidades Kichwas, para el análisis realizado se trabajó con los datos de 32 comunidades Kichwas, que representan un 11, 85% del total de comunidades existentes en la Reserva de Biosfera Sumaco, esto a la vez representa un 16,93% del total de Comunidades Kichwas. Las comunidades estudiadas están distribuidas en las Provincias de Napo, Orellana y Sucumbíos y ubicadas en la Zona de Amortiguamiento y en la Zona de Transición de la Reserva de Biosfera Sumaco. El sistema de producción y uso de suelo está orientada a la subsistencia, debido a lo que produce la Chakra es para consumo familiar, y no dan un buen uso al suelo, tienen una agricultura de subsistencia, los ingresos diarios que perciben los indígenas Kichwas en el estudio no alcanzan el Salario Digno peor aún el Salario Básico Unificado. Es por eso que los indígenas optan por realizar otras actividades como: trabajo de la mujer, tala del bosque y hasta emigrar hacia las ciudades para tener ingresos adicionales u otra actividad productiva que les permita cubrir en parte sus necesidades.

    (2013-11-07) Zúñiga Altamirano, Segundo Fabián; Sánchez Cobo, Pedro
    El propósito de la investigación es la generación de nuevos conocimientos y tecnología para la producción limpia, mediante la aplicación de micorrizas (Pisolithus tinctorius) en dos variedades del cultivar de tomate de árbol (Solanum betacea), en las condiciones agroecológicas de la Granja Experimental Docente Querochaca de la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Ambato. Los mejores resultados en las variables altura de planta, número hojas/planta, longitud de hojas (bajera, media y bandera), peso y diámetro del tallo, peso y volumen del sistema radicular, en la Fase de vivero con respecto a los testigos, se alcanzaron en los tratamientos que recibieron micorrizas en dosis de 20 g/planta. En la Fase de campo se registraron resultados con la misma tendencia con la aplicación de 60 g/planta de micorrizas. Estos resultados influyeron en mejor crecimiento y desarrollo de las plántulas, así como en la variación de la población de los microorganismos del suelo, por esta razón se está recomendando su aplicación a través de una propuesta técnica elaborada para el efecto. Descriptores del trabajo de investigación: plantas de tomate de árbol, micorrizas, vivero, campo, análisis y microbiológico del suelo.
