POMBOZA-TAMAQUIZA, Pablo et al. The Influence of biol in the crop yield of Lactuca sativa L. variety Iceberg. J. Selva Andina Biosph. [online]. 2016, vol.4, n.2, pp.84-92. ISSN 2308-3867.

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 at random, with factorial arrangement of 3x2 1 with three repetitions. We evaluated: plant height, diameter of the main stem, days to harvest, weight and diameter of the bud commercial, performance in kg/plot neta and performance in kg/experimental unit, conducted the significance test of Duncan to 5%. The results showed that the dose of 6 per cent applied every 15 days treatment D3F2, contributed to the larger diameter of the bud commercial (25.9 cm); the greater weight of cogollo commercial (1.14 kg) and the higher performance (549 kg/experimental unit). This suggests that the implementation of biol can be an important ecological alternative to fertilize organic farming as the lettuce by reducing the use of fertilizers in chemical synthesis and production costs.

Keywords : Biol; efficient microorganisms; dose; performance; lettuce.
