Correla??o e Dependência Espacial de Atributos do Solo, índice de Clorofila e Produtividade do Milho

摘要

This study aimed to quantify the spatial dependence of soil chemical properties, chlorophyll index in stages V3, V6and R1 and corn yield, and analyze the spatial correlation between them. Soil properties were evaluated in 2010and 2011 and the rate of chlorophyll (with clorofilómetro) and productivity in the years 2011 and 2012. The studiedattributes presented spatial dependence structure, allowing the site-specific management. It also observed theexistence of spatial correlation between attributes, demonstrating the importance of studies in this area, identifyingwhich attributes influence the development of culture.
