The cocoa shade and manurial experiment at the West African Cocoa Research Institute: III. Physiological results
A shade and fertilizer experiment has been described and the effects of the treatments on yields and the soil have been discussed in two preceding papers (Cunningham and Lamb, 1959; Cunningham et al., 1961). It was considered that a knowledge of the use of fertilizer application and shade removal in the culture of cocoa would be inadequate without a study of the effects of the treatment on the physiology of the cocoa tree. The results presented here are concerned with the influence of added nutrients and increased light intensity on the vegetative growth of the trees and their flowering, setting and wilting behaviour. Pound (1936) reported on the influence of fertilizers on the physiology of cocoa and reviewed earlier work. Later, the physiological aspects of an extensive shade and fertilizer trial carried out in Trinidad (Evans and Murray, 1953) were discussed by Murray (1954). The present results to some extent collate the earlier findings and enlarge them, particularly with regard to "cherelle wilt". (Resumen tomado CATIE-ST BT-5)
