    Evaluación del biofertilizante foliar a base de frutas (Ferti Fruit) en la asimilación de nutrientes en la lechuga (Lactuca Sativa L.).
    (2017) Ojeda Vargas, Luis Alberto; Pérez, Marco
    The research work titled "Evaluation of the fruit biofertilizer (Ferti fruit) in the assimilation of nutrients in lettuce (Lactuca Sativa L.)" was carried out in the Olmedo sector, belonging to the Pelileo canton, Tungurahua province; with an altitude of 2580 msnm. The geographic coordinates are: 01° 19' 13.9'' South latitude and 78° 32' 07.4'' West longitude. The research was carried out in order to evaluate the amount of nutrients that the crop can to receive from the biofertilizer, being this the only nutritive contribution that the plant had throughout its cycle, since it was on a substrate chemically inert. The treatments were three according to the applied doses; V1D1 3 ml / l, V1D2 5 ml / l, V1D3 7 ml / l. For the establishment of the test its used a random block design with four replicates. No statistical analysis was used because sub-samples were taken from each replicate to form a composite sample from each treatment. The results were interpreted in a comparative way. Three applications were made with the biofertilizer based on fruits, the same ones that were done at 20, 40 and 60 days after the transplant. To determine the concentrations of nutrients by the plant, foliar analyzes were performed before and after each application. For that purpose, samples were taken from lettuce leaves, which were sent to the Soil and Thermochemical Laboratory of the Faculty of Agricultural Sciences of the Technical University of Ambato. When performing the interpretation of the results, it was determined that the V1D3 treatment (7 ml / l) contributed a higher concentration of nutrients to the plant, with minimal differences in the assimilation of the other nutrients in the three treatments; this is evidenced by greater growth and uniformity in lettuce plants compared to other treatments.
