Filho,Luís Carlos Iuñes de Oliveira; Filho,Osmar Klauberg; Baretta,Dilmar; Tanaka,Cynthia Akemi Shinozaki; Sousa,José Paulo.
ABSTRACT: Collembolan species are differently affected by soil tillage (conventional, minimum tillage, and no-tillage) and are known to modify plant growth. This study relies on the relationships between Collembola community structures and land use systems as a proxy for characterizing changes in soil quality. Thus, Collembola community structure (eco-morphological groups - edaphic, hemiedaphic and epigeic, and morphotypes) were examined in a no-tillage system and crop-livestock integration system to evaluate the discriminative power of the Collembola community structure and to determine which soil properties drives structural diversity. Thirty-eight morphotypes of Collembola were recorded in this study, 11 belonging to the edaphic eco-morphological group,...

COELHO, G. R. C.; TOLEDO-SOUZA, E. D. de; CAFÉ FILHO, A. C.; LOBO JUNIOR, M..
The effects of tillage systems on the dynamics of web blight caused by Thanatephorus cucumeris and yield of common bean (Phaseolus vulgaris) cv. Pérola were studied in three field experiments during the planting seasons of 2004/2005, 2005/2006 and 2006/2007. Congo grass (Urochloa ruziziensis) was managed in a naturally infested field to establish the following cropping systems: no-till (NT), minimum-tillage (MT) (disking with partially incorporated straw); and conventional tillage (CT) (residues burial by soil plowing). The area under disease progress curves (AUDPCs) and the disease progress rates were generally low in the NT system during the three cropping seasons, most likely due to the benefits of grass mulching. In general, AUDPC values were higher in...
