Although several studies about the effects of environmental factors on the development of flowers and fruits have already been done, few of them were dedicated to the identification, under field conditions, the period of time
necessary to reach a water deficit sufficient to be efficient in promoting uniform coffee flowering, mainly considering different systems of cultivation, among which irrigation played an important role. Moreover, in the field, small restrictions faced by the root system and a more gradual development of water stress might lead to different responses from the plant.
