- Abstract
Given the importance of crop-livestock-forest integration systems (iLPF), it is essential to carry out research on height modeling to support the management and quantification of available resources. In this study, we aimed to adjust traditional models of hypsometric relation and to evaluate the effect of spacing and planting arrangements in the equations adjustment. The data were obtained from the eucalyptus trees in an integrated-crop-livestock-forest system (iCLF), in experimental areas implemented by the Brazilian Agricultural Research Corporation (Embrapa Agrossilvipastoril), located in the municipality of Sinop, northern region of Mato Grosso, Brazil. The precision and accuracy of the hypsometric models was evaluated through statistical indicators and graphic residue analysis. The influence of spacing and planting arrangement on the hypsometric relation was performed through the model identity test of Gaybiil (2000). Based on the statistics and graphical analysis the Assmann model presented better accuracy of fit for total height estimation. To estimate the commercial height, the Hyperbolic model obtained better performance. The identity test revealed that plant spacing, and arrangement influence significantly the hypsometric relationship and a single equation should not be adjusted to represent the total and commercial height in the different treatments in iCLF system.
