Comportamento do índice NDVI em relação à infestação de plantas daninhas na cultura de sorgo sacarino em Sinop-MT

Abstract

Work carried out by Student Vinícius Munhoz Ruhoff, whose title is NDVI index behavior in relation to weed infestation in sweet sorghum cultivars in Sionp. The project’s supervisor was Dr. Cassiano Spaziani, together with the co-supervisor, Dr. Guilherme Capristo. Sorghum is another grain that makes up animal feed, given its importance in the diet of animals, it is necessary to understand how the crop behaves in the face of the great challenge of controlling invasive plants. With the help of new technologies, the present work sought to measure the behavior of two sorghum cultivars CMSXS 5012 and CMSXS 5017, measuring the NDVI and GreenSeaker (Normalized Difference Vegetation Index) through the UAV (unmanned aerial vehicle) under infestation and absence of weeds, in addition to observing the morphological behavior of the plant. The work was carried out in a randomized block design, with 4 replications, of the following treatments, first: in coexistence with the weed community during different phases of its cycle; 3 (V3), 5 (V5), 7(V7), 9(V9), 11(V11); second: the crop remained free from weed interference, from emergence until the end of the same periods described above.
