%X Nitrogen is one of the essential nutrients for crop production, interacting in a very complex environment, so its monitoring is important both in economic sphere as environmental. This work aimed to discriminate doses of nitrogen from hyperspectral data in sugarcane. The evaluations were conducted at different stages of development of plants under the effect of different nitrogen doses in sugarcane. Leaf spectral measurements were taken and sent to the laboratory of foliar analysis to determine the nitrogen content. The spectral curves were grouped according to the doses of nitrogen applied, showing that it is possible to estimate foliar nitrogen from hyperspectral data, when the culture reaches approximately 140 days after harvest.
