Evaluation of certain factors affecting the yield of cacao in Ecuador
An evaluation of certain factors affecting the yield of cacao in Ecuador is discussed. Among the factors considered are: amount of rainfall, incidence of witches' broom disease and Monilia pod rot disease, per cent of total sunlight falling on the cacao trees, area of plantation in cacao, and area of land per tree. Correlation coefficients indicate a rather complicated interrelationship among rainfall, witches' broom disease and Monilia pod rot disease. A highly significant negative correlation is shown to exist between yield and rainfall yield and witches' broom, and between yield and area of plantation. The data, however, indicate no correlacion between yield and incidence of Monilia pod rot disease although Monilia pod rot disease is highly significantly correlated with witches' borom disease. An explanation is offered for this curious relationship as well as for the lack of correlation between Monilia pod rot and yield.
