(Mukerji) ; 8 maunds [650 lbs.] (Duthie & Fuller) ; about 700 lbs. 

 (Spon's Encyc. p. 946) ; ranging from 150 lbs. to 1200, but estimated 

 on an average at- 640 lbs. (Journ. Soc. Arts, xli. 1893, p. 791). 



Whether results comparable with those experienced in India are to 

 be attained in W. Africa or not, the plant can be recommended for 

 growing, amongst other crops, :cocoa, coffee, rubber, &c, as a green 

 manure, or cover to prevent weeds. In India, when used for green 

 manure, the plants are usually uprooted, when two to two-and-a-half 

 months old, and ploughed in. It is for this purpose considered pre- 

 ferable to one or two maunds [82-164 lbs.] of oil-cake per acre (Watt, 

 Comm. Prod. India, p. 433).
