Resumo: | Plant growth promoter microorganisms have been studied as important tools for increasing crop production. Lettuce is the most consumed hardwood crop in the world. Numerous microorganisms are capable of acting in a beneficial way in the growth of this culture. The objective of the present study was to evaluate the efficacy of Trichoderma and Pseudomonas on the microbial biomass, enzymatic activities in sandy soil and lettuce production. The experimental design was completely randomized with ten replicates and treatments: CONT (absolute control); CM (control with cattle manure fertilization); CMB (with fertilization and Pseudomonas sp.); CMF (with fertilization and T. aureoviride) and CMBF (with fertilization and the two microorganisms combined). The fertilizer used was organic with cattle manure in a dose recommended for the culture. This study evaluated the production of lettuce, microbial biomass and the enzymatic activity of acid phosphatase, alkaline phosphatase and urease. The combined application of CMBF was efficient in increasing lettuce production, because it increased 85% of the cv. Veronica cultivated on sandy soil. The combined use of plant growth promoting microorganisms resulted to an increase in microbial biomass. In lettuce crops, it is recommended to use T. aureoviride URM 5158 and Pseudomonas sp. UAGF 14 in lettuce crops, because improved lettuce production, improves the biochemical quality of soils measured by absolute and specific enzymatic activities per unit of microbial biomass. |

Lactuca sativa (alface) é a hortaliça folhosa mais consumida em todo mundo. Inúmeros micro-organismos podem atuar de forma benéfica no crescimento desta cultura. O objetivo do presente trabalho foi avaliar a eficácia de isolados de Trichoderma e Pseudomonas sp. na biomassa microbiana, atividades enzimáticas em solo arenoso e produção da alface cultivada com alface. O experimento foi conduzido em delineamento experimental inteiramente casualizado com dez repetições, sendo os tratamentos: CONT (controle absoluto); CM (controle apenas com a fertilização); CMB (com fertilização e Pseudomonas sp.); CMF (com fertilização e T. aureoviride) e CMBF (com fertilização e os dois micro-organismos combinados). A fertilização utilizada foi a orgânica pela adição de esterco bovino em dose recomendada para a cultura. Avaliou-se a produção de alface, a biomassa microbiana e a atividade enzimática da fostafase ácida, fosfatase alcalina e urease. A aplicação CMBF foi eficiente para o aumento na produção de alface, pois incrementou 85% da produção da cv. Verônica em solo arenoso. O uso combinado de micro-organismos promotores de crescimento de plantas incrementam a biomassa microbiana. Recomenda-se o uso de T. aureoviride URM 5158 e Pseudomonas sp. UAGF 14 no cultivo de alface, pois além de melhorar a produção, melhora a qualidade bioquímica dos solos mensurados por atividades enzimáticas absolutas e específicas por unidade de biomassa microbiana.Universidade Federal Rural do Semi-Árido2018-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/721810.1590/1983-21252018v31n408rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 860-870Revista Caatinga; v. 31 n. 4 (2018); 860-8701983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7218/9855Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessMoraes, Marcele de Cássia Henriques dos SantosMedeiros, Erika Valente deAndrade, Dayane da Silva deLima, Leandro Dias deSantos, Ivonaldo Carlos da SilvaMartins Filho, Argemiro Pereira2023-07-20T13:52:07Zoai:ojs.periodicos.ufersa.edu.br:article/7218Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:34.171742Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
