The mung bean is a grain of the Vigna genus not widespread in Brazil compared to carioca beans. Its consumption occurs in the form of Moyashi, that is, bean sprouts. In view of the above, the objective of this work was to determine the growth of the 'Crystal' cultivar under the influence of different water levels in the soil, based on the field capacity (FC), under the application or not of nitrogen (N). The experiment was conducted in 10L pots in the greenhouse of the vivarium of the Federal University of Mato Grosso - Campus of Sinop, from December 12, 2017 to January 20, 2018. The experimental design was in randomized blocks design with four replicates, in a 2x5 factorial scheme. The first factor with two variables, nitrogen application (urea) during planting at 30kg ha-1 and the second factor with five variables, the different water levels based on FC, 25%, 50%, 70% , 100% and 150% of the CC, with watering every three days. Forming 40 composite plots consisting of two vessels. The total chlorophyll content (TCT), plant height (PH), stem diameter (SD), number of leaves (NL), foliar area (AF), root dry matter (RDM), above ground dry matter (AGDM), and relative water content (RWC).It is verified that the application of 30 kg ha-1 N increases the vegetative growth of the plant, except the root, and the optimal water level based on the FC is between 50 and 70%.
