Studies on the flushing of cocoa in Ghana
Recordings of flushing were made at the University of Ghana, Agricultural Research Station, Kade, using an improved scoring method. Flushing in edge, centre, shade and unshaded cocoa follows a regular sequence, individual trees tending to flush at intervals of 10 to 11 weeks in Ghana. This rhythm is probably endogenous. The major flush occurs in March and is markedly greater in amplitude than all subsequent flushes. Under shade, there is a greater tendency for flushes subsequent to the major one to be supressed. In unshaded conditions flushing commences earlier and lasts longer than in shaded conditions. Flushing is greater in amplitude at isolated edges than elsewhere but the differential is less marked in the major flush. Recordings on individual trees show that flushing is most extensive on those parts of the canopy receiving maximum isolation and least intensive where maximally shaded. It is suggested that light may be the most important of the factors associated with the incidence and intensity of flushing
