Produção de biomassa de erva-cidreira [Lippia alba (Mill.) N.E.Br.] sob adubação com composto de capim elefante inoculado e sem inoculação de actinomicetos

L. alba is a species of the family Verbenaceae widely used by the Brazilian population, because of the soothing, gentle antispasmodic, analgesic, expectorant, sedative, anxiolytic and smoothly. For the implementation of the experiment produced organic compound of elephant grass (Pennisetum purpureum Shum.) + manure at 70% plant material and 30% manure, uninoculated and inoculated with the actinomycete Streptomyces genus, AC16, AC26, AC92 and AC103. The compounds were placed in polyethylene bags containing 10.0 kg of soil added in a proportion equivalent to 20 t ha-1 and re-apply after the first harvest. The harvests of the shoots were taken at 75 and 165 days after transplantation. The roots were harvested after the second harvest. Dealing with organic fertilization promoted the average increase in biomass production of lemon grass 184, 83, 125, 115 and 122% for the dry stem biomass (MSPA) in the first harvest, second harvest of MSPA, total shoot biomass (MSTPA), dry biomass of the root (MSR) and the total crop biomass (MST), respectively, compared with the control, but no effect of inoculation of actinomycetes in compost. Under the conditions of this study was conducted, it was concluded that the organic compound fertilizer with elephant grass positively influenced the production of dry biomass of L. alba, but the injection of the compounds of the actinomycetes, without influence.
