Summary

Cocoa was used as a test crop to compare the use of nine plant species and natural regeneration as ground covers in plantations. The nine species were Tephrosia hookeriana and villosa mixtures, Indigofera sumatrana, Flemingia congesta, Desmodium asperum, Cassia tora, Indigofera spicata, Crotalaria longithyrsa, Mimosa invisa, and Tithonia diversifolia. F. congesta and T. diversifolia gave the best and most persistent ground cover. Significant differences appeared in the effects of the covers on cocoa jorquetting, heights of jorquette, stem diameter and yields. T. diversifolia retarded cocoa development (to as low as 34% of control) while the others appeared to improve it. Yields in plots of Tephrosia mixture, I. sumatrana, and F. congesta were respectively 72, 59 and 54 per cent higher than under natural regeneration.
