Humus líquido y microorganismos para favorecer la producción de lechuga ( Lactuca sativa var. Crespa) en cultivo de hidroponía

Abstract

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