Resumo: | The vegetal productivity depends on several factors, including the bulk density and the soil porosity. The corn grains yield (GY), under no-tillage system and irrigated, and the following soil attributes (particle density-PD, bulk density-BD, and the total porosity-TP), in a Dystroferric Red Latosol (Haplic Acrustox), located at the Experimental Station of the Faculdade de Agronomia (Unesp), in Ilha Solteira, Sao Paulo State, Brazil (22º23’’ latitude S; 51º27’’ longitude W), were analyzed in the crop year 2004/2005. The aim was to study the linear and spatial correlations among the attributes. A geostastical grid to collect soil and plant data was installed with one hundred and twenty sample points, in an area of 0.8 ha. The soil attributes showed low variability of their data, although it showed to be on average at the GY. The BD and TP, in the soil surface, did not change randomly. They showed an excellent spatial performance, with ranges between 28.6 and 60.6 m. The multiple linear correlations showed that the TP1, TP3, and BD3 were significant attributes when they correlated with the GY. Among the soil attributes, the simple linear correlations were very elastics. Thus, when in correlations with the GY they showed little variability. With reservation due to low correlation, with the increase of the BD3 the GY decreased. Differently, the spatial correlations among the soil attributes and the GY were practically nulls. However, they were high when exclusively among every all the other attributes of the soil. |

No ano agrícola 2004/2005, na Fazenda Experimental de Ensino e Pesquisa da Faculdade de Engenharia (Unesp), Campus de Ilha Solteira, Estado de São Paulo (22º23’’ latitude S; 51º27’’ longitude W), foram analisados a produtividade de grãos de milho (PG), irrigado com pivô central, as densidades da partícula (DP) e do solo (DS) e a porosidade total (PT) de um Latossolo Vermelho Distroférrico, sob plantio direto. O objetivo foi estudar as correlações lineares e espaciais entre os atributos. Foi instalada uma rede geoestatística, para a coleta dos dados do solo e da planta, contendo 120 pontos amostrais, numa área de 0,8 ha. Os atributos do solo apresentaram baixa variabilidade de seus dados, sendo média no da planta. A DS e a PT, na camada superficial, e a PG não variaram aleatoriamente. Elas seguiram padrões espaciais bem definidos, com alcances entre 28,6 e 60,6 m. As correlações lineares múltiplas indicaram que a PT1, a PT3 e a DS3 foram atributos significativos, quando correlacionados com a PG. Entre os atributos do solo, as correlações lineares simples variaram elasticamente. Contudo, quando correlacionados com a PG, tais correlações pouco variaram. Ainda que com reservas devido à baixa correlação, com o aumento da DS3 ocorreu uma diminuição da PG. Por outro lado, as correlações espaciais entre os atributos do solo e a PG foram praticamente nulas, sendo, contudo, elevadas quando exclusivamente entre aqueles do solo.Universidade Estadual de Maringá2008-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/93910.4025/actasciagron.v28i3.939Acta Scientiarum.
