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 from 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 images of the MDE and MDT and through the orthomosaic the crown area was evaluated. Evaluations 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, seed and grafting, respectively, were 3.78 m, 2.99 m and 2.67 m and ii) the average crown area of the plants obtained by root, seed and grafting is 13.09m2; 10.45m2 and 8.04m2.
