CANAVALIA ENSIFORMIS (jACK BEAN) 8i 



case care must be taken to pull every other row and plough 

 it in in good time, to avoid depriving the small canes of 

 too much light. In any case, if there is a danger of this 

 happening through growth being too strong, whether the 

 plantation is sown in successive or alternate rows, it is only 

 necessary to slash along on each side of it to prevent the 

 small canes from being overrun. 



Directly the stems begin to bloom the pods rapidly 

 increase in size and soon form a considerable proportion 

 of the total weight of the crop ; later on the weight of the 

 pods exceeds that of the remainder of the plant. 



^.—Sowing on December 12th, every alternate row; 

 March 13th following, the total weight produced to the 

 hectare was 12,300 kilos; the pods already developed forming 

 25 per cent, of the total crop. 



B. — Same sowing; the weight of the crop per hectare on 

 April 17th was 13,600 kilos; the majority of the leaves had 

 fallen, but the seeds in their pods were well advanced and 

 formed 67 per cent, of the total crop, that is to say, their 

 weight exceeded that of the stems. 



C. — Sowing on March 15th; harvest on August 14th 

 following; the pods, now well developed, were badly attacked 

 by grubs. They formed 70 per cent, of the total crop, which 

 weighed 9,500 kilos (planting in alternate rows). 



Analyses have been made of the whole crop, stems and 

 pods. Although it cannot be said that beasts eat the stems 

 of the Jack Bean with any relish, we nevertheless append 

 the analysis from the point of view of fodder : —
