THE CULTIVATION OF COCOA 177 



The good effect of the mulching was shown not 

 only by the high yield but also by the fact that the 

 individual trees on the mulched plot were much finer 

 and better developed than those on the other plots. 



Attention should further be drawn to the fact that 

 the yields are high on all the plots of this field, and on 

 plots 4 and 5 even abnormally high : a yield of 1800 

 to 2000 Ibs. (800 to 900 kilograms) per acre is certainly 

 exceptionally large. 



In two other series of experiment plots, where the 

 different effects of pen manure and various others 

 (compost, bone-meal, dried blood and some chemical 

 manures) were compared, the result was in favour of 

 the pen manure, which gave the highest profits. In 

 Grenada the experiment plots gave the highest yield 

 when pen manure was given. 



It has already been mentioned that the difficulty
