Résumé

Propagation of rooted cutting of cocoa (Theobroma cacao L.) and planting in the semi-arid of the state of Bahia were studied. The results permit to conclude that there is an interaction between clones and cuttings harvest period, being January and February the best months. Planting was done on March 2003 under temporary shade of prata anã (dwarf silver) banana variety at the same planting spacing used with cocoa. Water was provided by a drip irrigation system and nutrients by fertirrigation. The other management practices were adapted considering the region edaphoclimatic conditions. The evaluations were quarterly measuring : plant height and diameter, flowering, flushing and fruiting. Of the found results is worth noting the growth, vigor, average production of 90 kg ha-1 of dry beans at 21 months, with remark to PH 16 with 110 kg ha-1 of dry beans. Flowering occurred in a "gregarious" form in quarterly periods. It was not observed negative effects of air relative humidity and temperature on growth, pollination and fruiting of the cocoa plant.
