Variabilidade espacial Artocarpus altilis a partir de processamento digital de imagens de Vant

Abstract

The breadfruit, Artocarpus altilis (Parkinson) Fosberg, stands out for its nutritional importance. Needing to know the spatial variability of breadfruit attributes through geostatistics and test the use of UAV technology in the crop. The objective of this work was to verify the spatial variability of Artocarpus altilis using digital processing of UAV images. The stand had plants obtained from seeds, grafting and roots. The height of the breadfruit trees was determined thanks to the subtraction of the MDE - MDT, this was possible due to the good quality of the MDE and MDT images and through the orthomosaic the canopy area was evaluated. Assessments of spatial variability resulted in greater height and area and canopy for root propagation, followed by plants propagated by seed and grafting. The results of the analysis of heights and canopy area under different forms of propagation were: i) the average heights of plants obtained by root, seeds and grafting, respectively were 3.78 m, 2.99 m and 2.67 m and ii) the average canopy area of ​​plants obtained by root, seeds and grafting are 13.09m2, 10.45m2 and 8.04m2.
