When coffee plants are watered at relatively short intervals, so as to maintain the water content of the soil at close to field capacity, the flower buds remain dormant and no fruits are formed. Irrigation or rain induces flowering only when preceded by a period of water shortage. Water stress is apparently essential to break the dormancy of coffee flower buds.
