“…Isso foi menos intenso no plantio direto (PD), que apresentou valor médio de Ds ligeiramente superior ao dos demais tratamentos na camada mais superficial, embora a diferença não fosse significativa (p>0,05). Outros autores estudaram o efeito do sistema PD sob os atributos físicos do solo e evidenciaram esse aumento da Ds, devido à compactação causada pelo tráfego de máquinas e ao não revolvimento do solo (Fabrizzi et al, 2005;Cardoso et al, 2006).…”

“…Outros autores também verificaram maior armazenamento de água no solo em função da cobertura vegetal (Dalmago et al, 2009;Seki et al, 2015). A proteção por meio de resíduos vegetais reduz a evaporação, aumenta a infiltração da água no solo (Fabrizzi et al, 2005), diminui a amplitude térmica da superfície do solo e, consequentemente, conserva a humidade .…”

R E S U M OO trabalho teve como objetivo avaliar a influência dos diferentes sistemas de cultivo do cafeeiro na biomassa e atividade microbiana do solo. O delineamento experimental consistiu em blocos casualizados, com cinco repetições. A primeira avaliação foi realizada no mês de abril e a segunda no mês de julho de 2015. Os tratamentos foram constituídos por três sistemas de cultivo do cafeeiro e duas áreas testemunhas: 1) Cafeeiro em consociação com espécies arbóreas e Urochloa cv. decumbens; 2) Cafeeiro em consociação com Urochloa cv. decumbens; 3) Cafeeiro em monocultura; 4) Área com solo em pousio e 5) Fragmento de vegetação nativa. A biomassa e atividade microbiana foram avaliadas em amostras de solo colhidas à profundidade de 0,0-0,10 m. As variáveis avaliadas foram: carbono da biomassa microbiana, respiração basal, quociente metabólico, quociente microbiano e carbono orgânico do solo. Avaliou-se também o acúmulo de manta morta (t ha -1 ) e a humidade do solo (kg kg -1 ). Os sistemas Fragmento de vegetação nativa, Cafeeiro em consociação com espécies arbóreas e U. cv. decumbens e Cafeeiro consociado com U. cv. decumbens favorecem a biomassa e a atividade microbiana do solo, independente da época de amostragem. Palavras-chave: bioindicadores, Coffea arabica, espécies arbóreas, Urochloa cv. decumbens A B S T R A C TThe work aimed to evaluate the influence of different coffee farming systems in soil microbial biomass and activity. The experimental design consisted in randomized blocks in split plot, with five repetitions. Two seasons were evaluated, the first in April and the second in July 2015. The treatments consisted of three coffee cultivation systems and two control areas: 1) Coffee intercropped with trees species and Urochloa cv. decumbens; 2) Coffee intercropped with Urochloa cv. decumbens; 3) Coffee in monoculture; 4) ground fallow and 5) native vegetation fragment. The soil microbial biomass and activity were assessed in soil samples collected at 0.0-0.10 m depth. The following variables were evaluated: microbial biomass carbon, basal respiration, metabolic quotient, microbial quotient and soil organic carbon. Litter accumulation (t ha -1 ) and soil moisture (kg kg -1 ) were also evaluated. The systems fragment of native vegetation, Coffee in consortium with tree species and U. cv. decumbens and Coffee intercropped with U. cv. decumbens favour soil microbial biomass and activity, regardless the sampling time.

“…Moreover, Cavalieri et al (2009) reported that the longterm use of no-tillage resulted in increases of organic carbon and pore connectivity. Fabrizzi et al (2005) have also found that penetration resistance showed differences between tillage systems, being higher under no-tillage at all sampling depths.…”

“…For the determination of root length density (RLD) and root surface (RS), the stained root samples were placed on a high resolution scanner (Hewlett Packard 4c, Palo Alto, CA, USA) and images captured using Delta-T software was used, (Delta-T Scan version 2.04; ported that perennial weeds had higher density under the no-tillage system. Moreover, tillage intensity influences growth and yield of maize (Banda, 1997;Fabrizzi et al, 2005;Karumatilake et al, 1997;Materechera and MlozaQin et al, 2006). Arbuscular mycorrhizal (AM) fungi are ubiquitous in agricultural soils.…”

Field experiments were conducted to determine the effects of tillage system and rimsulfuron application on weed flora and growth of maize (Zea mays L. Mitic F1) at a site with no history of pesticide use for the last 5 years. A randomized complete block design was employed with three replicates per treatment (conventional tillage without rimsulfuron application (control), no-tillage with rimsulfuron application (NT+Rim) and conventional tillage with rimsulfuron application (CT+Rim)). The lowest leaf area index, dry weight and yield of maize were recorded in NT+Rim plots. In addition, the highest soil bulk density was determined in NT+Rim plots. Moreover, the rimsulfuron application resulted in significant reduction in the root growth and arbuscular mycorrhizal (AM) colonization. The lowest root biomass, root length density, root surface and AM root colonization was found in CT+Rim plots. The lowest weed number and biomass was also observed at CT+Rim plots. Sustainability yield index (SYI) shown that the maize crop is more stable under conventional tillage compared with no-tillage. Our results indicated that root growth was reduced significant by rimsulfuron application but statistically significant lower maize yield was obtained in no-tillage system.
