    Evaluación de coadyuvantes botánicos y abono orgánico (biol) enriquecido con minerales en el cultivo de col (brassica oleracea var. capitata)
    (2013-10-04) Zamora Carrillo, Nelson Roberth; Cruz Tobar, Eduardo
    La investigación se realizó en la Granja Agroecológica ubicada en el cantón Píllaro, propiedad del H. Gobierno Provincial de Tungurahua, en la que se evaluó los coadyuvantes botánicos: sábila (Aloe vera L.), tuna (Opuntia ficus-indica (L.) Miller) y el abono orgánico (Biol) enriquecido con minerales, en el cultivo de col (Brassica oleracea var.Capitata). Como principales resultados se destaca que el tratamiento C2D3F3, que recibió al coadyuvante tuna, en la dosis del 3% y aplicados a la frecuencia 3, permitió obtener el mayor rendimiento que es de 129,92 kg, ubicándose en el primer rango y lugar de la prueba de tukey al 5%, a continuación se ubicó el tratamiento C2D2F3 que recibió al coadyuvante tuna, en la dosis del 2% y aplicados a la frecuencia 3, con un rendimiento de 129,63 kg, ubicándose también en el primer rango y en segundo lugar en la prueba y en cuanto al tratamiento C1D3F3, que recibió al coadyuvante Sábila, en la dosis del 3% y aplicados a la frecuencia 3, se encuentra en el tercer lugar de la prueba y en el primer rango con un rendimiento de 129,58 kilogramos

    Extracción de cromo total de la capa arable de los suelos contaminados por carnaza con la aplicación de dos tipos de abono orgánico en el cultivo de fréjol (Phaseolus vulgaris)
    (2017) Quinapanta Cullpa, Laura Marisol; Ibarra López, Bertha Elizabeth
    The objective of this investigation was to determine the total chrome concentration of the arable layer of the soils as a consequence of the inadequate use of tannery residuals, by utilizing two types of organic fertilizers: humus soil and compost on a beans (Phaseolus vulgaris) crop in two doses; where we evaluated: the amount of chrome in the soil, days to fruit emergence, days to flowering period, height of the plant, length of the roots. Through the application of the H2C2 treatment (Humus soil 1 Kg/m2; compost 1kg/m2) in a beans (Phaseolus vulgaris) crop,the amount of chrome in the soil decreased considerably, reporting 29,56mg/Kg, which means a 70,9% reduction of the total amount of chrome present in the soil. Regarding to days to fruit emergence, the H2C1 (Humus soil 1 Kg/m2; Compost 0,5 Kg/m2) treatment had better results, showing 8 days to fruit emergence, compared to T witness which was 14 days. In the variable days to flowering period, the H2C1 (Humus soil 1 Kg/m2; Compost 0,5 Kg/m2) treatment presented an optimum result, being the earliest by reporting 71 days to flowering period, whereas the T witness presented 89 days. The H2C1 (Humus soil 1 Kg/m2; Compost 0,5 Kg/m2)treatment showed higher bean plants of 48 cm, while the T witness showed 33 cm in height. By using the H2C1 (Humus soil 1 Kg/m2; Compost 0,5 Kg/m2) treatment it was possible to obtain longer roots of 23 cm, while the T witness showed a root length of 10 cm. It is possible to conclude that the use of organic fertilizers: humus soil and compost, reduces the chrome concentration in the soil, and allows for the bean root and fruit development.

    Respuesta Productiva y Calidad de Fritura de Papa (Solanum Tuberosum l.), Var. Puzza, a la Aplicación de Titanio Y Abono Orgánico en Jaloa Alto, Quero, Tungurahua, Ecuador
    (2021-01) Moreta Villacrés, Robinson Fabricio; Pallo Paredes, Edwin Leonardo
    Potatoes (Solanum tuberosum L.) is cultivated in countries with a temperate climate and is a very important item for the diet of our country. It is well known that the Organic titanium (Org-Ti) is a production and quality bio-stimulant for crops and so is too, the positive impact of organic fertilizer (OF) in agriculture; but in the Ecuadorian Sierra, the benefits of Org-Ti and (OF) in potatoes (Solanum Tuberosum L.) should be studied. The study objective was to evaluate the productive response and quality of potato frying, var. Puzza, to the application of O-Ti and OF. The study was conducted at 3300masl from Dec. 2019 to Jun. 2020 in Quero, with a DBCA in divided plots and four replicas. The OF was the main plot (0 and 1.37 Mg ha-1) and the Org-Ti the subplot (0, 50, 100, 150, 200 and 250 mL 200 L-1). It was sown at 1.2x0.3m, two tuberseeds per stand and fertilized according to the soil analysis. At harvest, the tubers were categorized and samples were taken for nutrient and dry matter analysis and frying tests. The average productivity was 49.4 Mg ha-1; Org-Ti and OF did not affect this total (p > 0.10). No productive benefits of Org-Ti were observed, but a negative interaction with OF in large category tubers (p = 0.07) was evidenced. However, OF increased the thick category tubers by 1.2 Mg ha-1 (1.7%, p = 0.09), very Thick by 2.7 Mg ha-1 (4.7%, p <0.01); and reduced the small category by 2.2 Mg ha-1 (4.0%, p <0.01). Neither the Org-Ti nor the OF affected the nutritional content, dry matter and frying quality (p > 0.10). The Org-Ti did not improve potato productivity or quality but the OF did improve the volume of commercial potatoes (thick and very thick), whose price is higher than the small category, resulting a potential to improve the farmer's economy.
