Item Efecto de la aplicación de tres productos ecológicos para la prevención de mildiu velloso (Peronospora destructor) en cebolla de bulbo (Allium cepa var. Regal)(2016) Eugenio Torres, Jorge Luís; Cruz Tobar, Saúl EduardoThe need to create new alternatives for the control of pests and diseases in traditional cultures of our country, using agronomic techniques healthier control without causing deterioration of soil, water and the environment in general, reducing pollution for plants, animals and humans, make it necessary to investigate appropriate technologies to enhance this control, hence, onion bulb being a traditional crop and important segment of the agricultural economy is suitable for the development of research. This assessment of the effect of three organic products (potassium phosphate, copper, zinc and iron and cupric hydroxide), applied in three doses at two frequencies, for control of downy mildew (Peronospora destructor) in the cultivation of onion bulb (Allium strain var. Regal) was conducted in the field of Samanga, Canton Ambato, Tungurahua province, at an altitude of 2890 meters. With potassium phosphate application, the best results were obtained by reporting incidence smaller percentage (12.73%) and severity after 90 days of transplantation (20.21%), a result, the fastest growing plants experienced Leaf length (87.37 cm) and, equatorial diameter (6.72 cm) and bulb weight (154.60 g), achieving higher yields (7.59 kg / treatment). Within this product, the high dose (750 ml / 200 l) produced greater control, with the lowest percentage of incidence and severity; Likewise, applying the product with the frequency of every 15 days, the best results were obtained significantly menorando the incidence and severity of the attack. Descriptors: Allium cepa, ecological, downy mildew, potassium phosphate, incidence, severity, cupric hydroxide, agronomic techniques, organic products, frequencies.Item Evaluación de inductores externos de la activación del sistema inmunológico en el cultivo de rosas ( Rosa sp.)(2016) Reyes Recalde, Rubén RodrigoExcessive application of agrochemicals in the cultivation rose produces high environmental contamination plus it is a very important item to consider in obtaining flowers so I consider it necessary to carry out this investigation in order to find a viable alternative to chemical application , moving towards cleaner production roses that will benefit both the producer and workers who will be less exposed to these products. This experiment was performed in order to "determine the effectiveness of the application of external inducers of immune system activation in culture (Rosa sp.)". After obtaining the data in the field analysis of variance was performed also tests comparing means necessary as the Tukey test at 5% and the least significant difference test will be made as appropriate. design randomized complete block factorial arrangement 2 x 3 plus a control with four replications were made. The experiment was conducted in established culture of roses (Rosa sp) in which treatment and then proceed to take the field data as apply: Percentage of incidence, percentage of severity, presence of flavonoids, presence of jasmonates, performance, and postharvest lifeItem Determinación de la producción de trigo (Triticum vulgaris) y su incidencia en los ingresos económicos de los productores en la parroquia San Pablo provincia de Bolívar(2016) Salazar Ramos, Sonia María del CarmenItem Evaluación de la aplicación de tardígrados para reducir el desarrollo de bacterias fitopatógenas cultivadas in vitro(2016) Mangui Tobar, José ErnestoItem Caracterización Agro socioeconómica del canal de riego Mocha Quero Ladrillos(2016) Abril Espín, Edy Marinson; Zurita Vásquez, Hernán
