This paper, as Part II of a research carried out in Sergipe state, aims to determine evapotranspiration and crop coefficient of dwarf-green coconut (Cocos nucifera L.) based on lysimeter measurements and Bowen ratio-energy balance method. The reference evapotranspiration was obtained by the Penman-Monteith approach on daily-scale during the experimental period. The data acquisition system was used to obtain all data from the sensors necessary to determine the energy balance components. The water requirements of coconut palm during the phenological growth stage is 1263.30 mm, with daily average of 3.90 mm d(-1). The crop coefficient during this phenological growth stage varies between 0.50 and 1.80, with daily mean of 0.96.
