NUNEZ SOSA, Dania Bárbara et al. Response of carrot (Daucus carota L.) to the application of native microorganisms under organoponic conditions. Ctro. Agr. [online]. 2017, vol.44, n.2, pp.29-35. ISSN 2072-2001.

The present research was carried out in an organoponic belonging to the University of Matanzas. With the aim to evaluate the biochemical and productivity responses of carrot (Daucus carota L.) after the application of native microorganisms four treatments were analyzed (control, native microorganism's biopreparations with doses of 4 mL m^-2, 8 mL m^-2 and 10 mL m^-2, the ME were sprayed on 20, 40 and 60 days, respectively). The experimental design employed was a complete randomize block. The yield and its components as well as the biochemical parameters total soluble protein, carbohydrates and reducing sugar were measured. The obtained results suggested that the native microorganisms had a positive effect on the yield and its components in carrot plants, where 10 mL m^-2 was the most effective dose, increased 0,72 kg m^-2. The contents of soluble carbohydrates, reducing sugar and soluble proteins were also increased in a maxim value of 3.35 mg mL^-1, 17.6 kg m^-2 and 8.05 kg m^-2 respectively, with the application of the studied bioproduct.
