local.description.resumoTithonia diversifolia (Tithonia) is performed as an invasive species with a high adaptive potential that can be used for several purposes, including an alternative source of forage for different animal categories. The use of Tithonia is growing rapidly as farmers recognize its high accumulation of biomass, good nutritional value and adaptation to tropical environments. However, the effects of irrigation and nitrogen on the characteristics of Tithonia have been poorly studied. In this context, the objective of this study was to identify changes in the productive characteristics and morphophysiology of Tithonia under different irrigation simulations and nitrogen fertilization rates, seeking to understand its adaptive potential in different water and nutritional scenarios, improvements in the efficiency of the use of water and nitrogen and its potential for use in a global context. Field trials was a split-plot design with three replicates. Whole plots were irrigation rate (0%, 25%, 50%, 75% and 100% of crop evapotranspiration - ETc) and the subplots were the nitrogen fertilizer rate (0, 50, 100 and 150 kg ha-1.
