| dc.description | The generally irreversible drop in cocoa planting yields sometimes begins before the age of 10 years. In French Guiana, regeneration of a trial planting (planted in 1984) comparing 9 hybrids from Cote d'Ivoire with 3 local controls, which had becomelargely unproductive, was carried out in December 1993 by thinning 2 in every 4 rows to leave a final density of 833 trees/ha. The performance of the hybrid progenies was studied over the following 2 harvesting seasons, with regard to: yields (actual andpotential), rot rate and mean pod weight, vegetative development, yield:vigour ratio and correlations between vigour and productivity variables. The results showed a 35 to 65% increase in yields, as tree productivity was multiplied by up to a family meanof 4.24. Yields were very closely correlated to vigour. | |
