MONTANARI, Rafael et al. Correlation between common bean production and physical attributes of an Oxisol in Mato Grosso do Sul State, Brazil. Rev. Ceres [online]. 2013, vol.60, n.6, pp.772-784. ISSN 0034-737X.

In Brazil, common bean is in one of the most representative economic crops, not only because of its growing area but also because of the economic value of its production. In the crop year 2006/07, in Selvíria (MS), we analyzed the common bean yield as a function of some physical attributes of a Typic Acrustox in minimum tillage and center pivot irrigation system. The aim of this work was to evaluate among the soil physical attributes, under minimum tillage, those that better explain the variability of bean yield using the Pearson  and spatial correlations,. A geostatistical grid was installed to collect data from soil and plants, with 117 sampling points in an area of 2025 m2 and homogeneous slope of 0.055 m m-1. The results showed a low yield of bean, which occurred probably due to a lower density of plants that the system provided. Thus, for the  minimum tillage system, the bean yield could be explained as a function of total porosity and bulk density.
