Abstract

VELASCO, José; AGUIRRE, Gino  and  ORTUNO, Noel. Liquid humus and microorganisms to promote the production of Lettuce (Lactuca sativa var. Crespa) in hydroponic crop. J. Selva Andina Biosph. [online]. 2016, vol.4, n.2, pp.71-83. ISSN 2308-3867.

In an initial phase, a trial with growing hydroponic lettuce was installed, considering all the macro and micronutrients necessary and sufficient for growth, where treatments were applied with and without liquid humus, combining separately with inoculation of mycorrhiza and bacteria Bacillus type, observing that the significant effect by the individual use of the liquid humus is up to 50%. Subsequently, in a Phase II, different doses of only liquid humus with only mycorrhizae were evaluated, where applying of 8 L of pure liquid humus per 36 L of stock solution of hydroponics crop, the plants had the highest weight (40.7%), the highest altitude (39%) and the longest (42%) compared to the witness. Instead, the combination of liquid humus plus mycorrhizal is 6 L per 36 L of stock solution, which stimulated a further growth and weight of growing lettuce in hydroponics conditions. In general, the use of liquid humus decreased the production time from 60 to 52 days.

Keywords : Liquid Humus; humic acid; fulvic acid; mycorrhizae; Bacillus; lettuce.
