ABSTRACT:       Chrysanthemum is one of the most commercialized flower species in Brazil, however, there is little information related to the correct water management of the crop. Thus, the work seeks to determine the crop evapotranspiration (ETc) and obtain the cultural coefficients (Kc) of the pot chrysanthemum, in addition to assessing the water use efficiency (EUA) of the crop under different irrigation managements. The experiment was conducted in a protected environment in Santa Maria-RS, which a completely randomized design (DIC) was used, with five treatments based on the capacity of water retention in  the  vessel  (CRV)  (40,  60,  80,  100  and  120%  CRV),  with  16  repetitions,  each  pot  was  considered  one  repetition.  ETc  was determined by weighing Lysymetry, ETo was calculated by six different equations: Benevides-Lopez, Camargo, Linacre, Jensen-Haise, Hargreaves and Ivanov. Kc was obtained by the relationship between ETc and ETo. The evapotranspiration of the culture ranged between 153 and 264 mm. There was no significant difference in the EUA between the treatments studied. The average Kc was 0.98 for the vegetative phase, 1.29 from the beginning of the reproductive phase to the point of commercialization and 0.85 until the end of the reproductive phase.

RESUMO:       O crisântemo é uma das espécies florícolas mais comercializadas no Brasil, entretanto, há poucas informações relacionadas ao correto manejo hídrico da cultura. Desta forma, o trabalho busca determinar a evapotranspiração da cultura (ETc) e obter os coeficientes culturais (Kc) do crisântemo de vaso, além de avaliar a eficiência de uso da água (EUA) da cultura  sob  diferentes  manejos  de  irrigação.  O  experimento  foi  conduzido  em  ambiente  protegido  em  Santa  Maria-RS,  no  qual adotou-se o delineamento inteiramente casualizado (DIC), com cinco tratamentos baseados na capacidade de retenção de água no vaso (CRV) (40, 60, 80, 100 e 120% CRV), com 16 repetições, sendo cada vaso considerado uma repetição. A determinação da ETc se deu por lisimetria de pesagem, a ETo foi calculada por seis distintas equações: Benevides-Lopez, Camargo, Linacre, Jensen-Haise, Hargreaves e Ivanov. O Kc foi obtido pela relação entre a ETc e a ETo.A evapotranspiração da cultura oscilou entre 153 e 264 mm. Não ocorreu diferença significativa de EUA entre os tratamentos estudados. O Kc médio foi de 0,98 para fase vegetativa, 1,29 do início da fase reprodutiva até o ponto de comercialização e 0,85 até o fim da fase reprodutiva.
