Influencia del biol en el rendimiento del cultivo de Lactuca sativa L variedad Iceberg

The objective of the research was to assess the influence of biol enriched with efficient micro-organisms, in the ecological cultivation of Lactuca sativa L (lettuce) variety "Iceberg". The field test was carried out on the farm of Querochaca,Faculty of Sciences Agriculture, of the Technical University of Ambato. The studied factors were doses of biol (2%, 4%and 6%) and frequencies of application (8 and 15 days), I know used the experimental design of complete blocks atrandom, with factorial arrangement of 3x2 1 with three repetitions. We evaluated: plant height, diameter of the mainstem, days to harvest, weight and diameter of the bud commercial, performance in kg/plot neta and performance inkg/experimental unit, conducted the significance test of Duncan to 5%. The results showed that the dose of 6 per centapplied every 15 days treatment D3F2, contributed to the larger diameter of the bud commercial (25.9 cm); the greaterweight of cogollo commercial (1.14 kg) and the higher performance (549 kg/experimental unit). This suggests that theimplementation of biol can be an important ecological alternative to fertilize organic farming as the lettuce by reducingthe use of fertilizers in chemical synthesis and production costs.El objetivo de la investigación fue evaluar la influencia del biol enriquecido con microorganismos eficientes, en el cultivo ecológico de Lactuca sativa L (lechuga) variedad “Iceberg”. El ensayo de campo se realizó en la Granja de Querochaca, Facultad de Ciencias Agropecuarias, de la Universidad Técnica de Ambato. Los factores estudiados fueron dosis debiol (2%, 4% y 6%) y frecuencias de aplicación (8 y 15 días), sé utilizó el diseño experimental de bloques completos alazar, con arreglo factorial de 3x2+1 con tres repeticiones. Se evaluaron: altura de la planta, diámetro del tallo principal,días a la cosecha, peso y diámetro del cogollo comercial, rendimiento en kg/parcela neta y rendimiento en kg/unidadexperimental; se realizó la prueba de significación de Duncan al 5%. Los resultados mostraron que la dosis del 6%aplicado cada 15 días tratamiento D3F2, contribuyó al mayor diámetro del cogollo comercial (25.9 cm), al mayor pesodel cogollo comercial (1.14 kg) y al mayor rendimiento (549 kg/unidad experimental). Ello sugiere que la aplicación debiol puede ser una importante alternativa ecológica para fertilizar cultivos ecológicos como la lechuga reduciendo el usode fertilizantes de síntesis química y los costos de producción
