If we were to calculate from these tigures the yield from 

 a cultivation in successive rows, that is to say, from a full 

 cultivation, we should have 20,940 kilos of green forage to 

 the hectare. 



The amount abstracted by the total harvest would thus 

 be: — 



Silica 



Chlorine 



Sulphuric acid ... 



Phosphoric acid 



Lime... 



Magnesia 



Potash 



Soda... 



Oxide of iron ... 



Carbonic acid, &c. 



Total mineral matter

When the green matter is ploughed in, which is usually 

 the case in a rotation, no loss takes place, but it is different 

 when a seed crop is taken. In Reunion the consumption 

 of these seeds is a large one, and there is no doubt that 

 they are splendid eating peas. 



It is unfortunate that this plant cannot be cultivated in 

 Mauritius with any profit for the sake of its fruit, as the 

 seeds are in great favour, but the pods always swarm with 

 caterpillars which devour the seeds completely. Although 

 it grows well in Mauritius it is unfortunately impossible 

 to obtain any harvest.
