Variabilidade espacial da produção de feijão correlacionada com aspecto fisiológico em nitossolo vermelho distroférrico.

Abstract

The evaluation of the spatial dependence requires the use Geoestatistic Analisys. The culture of the beans was used to evaluate the spatial variability of the production, being able this being correlated with other physical-hidric attributes. This work had as objective to evaluated the degree of space dependence of the beans production being used geoestatistics tools, as base for future studies of handling of the soil, water and agriculture of precision. The experiment was lead in the Technical Center of Irrigation – CTI. In the field a quadrant in directions X and Y was defined, being that in each direction marked of 3 in 3m was made, until 48m. Randomized in the area was defined a more intense sampling to each 1,5m. For analysis of the data they had been used software MINITAB (descriptive statistics), VARIOWIN and SURFER (geoestatistic) the results showed the existence of spatial dependence of the beans production and that future studies must evaluate the causes of the variation.
