Summary: The management of apple orchards is conditioned by the form of cultivation adopted, which influences on plant yield, profitability and longevity of the area. This study aimed to evaluate the effects of management systems for conventional and organic apple production on soil physical properties and identify the variables that discriminate between the two production systems, using canonical discriminant analysis (CDA). The experiment was carried out in São Joaquim, SC, in two orchards, one under conventional system (CS) and the other under organic system (OS), both established in 2001, using Royal Gala cultivar, on M9 rootstock, in a Humic Cambisol. Soil samples were collected during 2008-2009 season in the layers 0-10 cm and 10-20 cm. The soil physical properties evaluated were particle size distribution, aggregate stability, represented by the mean geometric diameter (MGD), bulk density (BD), total porosity (TP) and degree of flocculation (DF). The results were tested for comparison of means and CDA. The OS had higher values of MGD and BD in the two layers. In the 10-20 cm layer, macroporosity was greater in the CS. The MGD in the layer 0-10 cm and microporosity in the layer 10-20 cm showed the highest values of parallel discrimination rate coefficient (PDRC), revealing that these properties were good indicators of soil physical quality and can be used to study changes in apple production caused by the production systems.

O presente estudo teve como objetivo avaliar os efeitos dos sistemas de manejo convencional e orgânico de produção de maçãs sobre atributos físicos do solo e identifi car os parâmetros que discriminam os dois sistemas de produção, por meio da utilização da análise canônica discriminante (ACD). O experimento foi realizado no município de São Joaquim, SC, em dois pomares, um no sistema convencional (PC) e o outro no sistema orgânico (PO), ambos implantados em 2001, com a cultivar Royal Gala, sobre porta-enxerto M-9, em um Cambissolo Húmico. As amostras de solo foram coletadas na safra 2008-2009, nas camadas de 0-10 cm e 10-20 cm. Os atributos físicos do solo avaliados foram granulometria, estabilidade de agregados, representada pelo diâmetro médio geométrico (DMG), densidade do solo (Ds), macro, micro e porosidade total (PT) e grau de floculação (GF). Os resultados obtidos foram submetidos ao teste de Tukey para comparação de médias e à ACD. O PO apresentou menores valores de DMG e macroporosidade na camada de 0-10 cm. Na camada de 10-20 cm, a macroporosidade e PT foram maiores no PC. O DMG na camada de 0-10 cm e a microporosidade na camada de 10-20 cm apresentaram os maiores valores de coeficientes de taxa de discriminação paralela (TDP), revelando que esses atributos são os melhores indicadores de qualidade física do solo e podem ser indicados para estudo de alterações na produção de maçãs provocadas pelos sistemas de produção avaliados.Universidade do Estado de Santa Catarina2012-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5253Revista de Ciências Agroveterinárias; Vol. 11 No. 3 (2012); 187-195Revista de Ciências Agroveterinárias; v. 11 n. 3 (2012); 187-1952238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5253/3462Rosa, Eliete de Fátima Ferreira daStüpp, João JoséAmarante, Cassandro Vidal Talamini doMafra, Álvaro Luizinfo:eu-repo/semantics/openAccess2022-07-01T15:00:53Zoai::article/5253Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2022-07-01T15:00:53Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
