Wheat and triticale crops are established as fundamental in the bread and cereal production chain, with wheat being a winter cereal widely cultivated in the third harvest of the cerrado and triticale being a product resulting from the artificial crossing between wheat and rye. are of such importance, it is essential that technologies are applied to different links in the chain with a view to improving production rates, such as the use of cultivars that perform better in the field and that are suitable for different conditions of water availability. Thus, the objective of the present work was to evaluate the possibility and adaptability of irrigated wheat and triticale in the third harvest in the cerrado region. To this end, an experiment was carried out at the Campo Escola Farm of the Federal University of Mato Grosso do Sul, in Chapadão do Sul – MS, comparing the wheat cultivars BRS Potyporã, BRS Gralha ZUL and the triticale IPR Aimoré, IPR Caiapó and BRS Surubim. Subjected to different levels of irrigation depth (30, 60 and 90%), using a completely randomized design (DIC) in a 5 x 3 factorial arrangement, evaluating plant height, number of grains per plant, mass of one hundred grains, number of panicles, vegetation indices (NDVI, NDRE, SAVI and EVI). At the end of the experiment, it was possible to conclude that when combining both analyzed variables, it is possible to observe that the Triticale cultivars were more resistant to variations in irrigation depth levels, presenting better performance in terms of height and mass, when compared to wheat. and the BRS Gralha azul cultivar proved to be superior to BRS Potyporã, when we analyzed only wheat. In general aspects, the wheat cultivar BRS Potyporã was the one with the lowest performance in both variables analyzed. Keywords: Irrigation, Productivity, Triticosecale wittmack, Triticum aestivum.
