Popis:	Cocoa crop in Colombia is characterized by low technification, with yields below 500 kg.ha -1 .year -1 . Inappropriate application of cultural practices related to the lack of knowledge about cocoa phenology, as to the times and factors that induce flowering, shoot growth and fruit filling, is one of the principal causes. Phenology of cocoa ( Theobroma cacao L) clones CCN-51, ICS-95, FCH-25 y LK-40 was characterized in 4 years old trees, data were taken monthly for one year in a Tropical moist forest (T-mf), with unimodal rainfall regime, in the municipality of Chigorodo (Antioquia), coordinates N 7° 36´ 52.5473´´ W 76° 39´ 32.8495´´, 30 masl, Mi Fortuna farm. The correlation (Spearman) between precipitation, water balance, number of hours with photosynthetically active radiation between 750 and 2200 umol.m -2 .s -1 (PAR hours) and the maximum and minimum temperature with vegetative and reproductive variables was calculated. A significant correlation (p
