CHAPTER IV. 

 COMPARISON BETWEEN VARIOUS ROTATION PEAS. 



Judging from the results obtained from our experimental 

 fields, it is difficult to say to which pea the preference should 

 be given. 



Although, viewed as a whole, all show an equal number 

 of good qualities, yet each individually shows some particular 

 property which may give it the preference according to the 

 conditions under which one is working and the type of culti- 

 vation it is wished to pursue. 



In fields entirely under a rotation the Lima bean, 

 Bengal bean, and trailing cowpeas will be seen to give 

 excellent results; on the other hand, in a mixed cultivation 

 the jack bean, dwarf cowpeas, and amberiques will give the 

 greatest advantages. 



At the same time it should be stated that these latter 

 \arieties are just as well suited to be cultivated alone as the 

 former, whose trailing stems preven-t their use with canes. 



It was interesting to ascertain what influence the distance 

 at which the plants were placed had on the proportional 

 yield of these peas, and with this object some plots were 

 planted at intervals of o'66 metre, and others at intervals of 

 I metre. In the majority of cases the yields of green matter 

 were higher, both when the plants were spaced at intervals 

 of o'66 metre and when planted singly instead of in pairs. 



However, it should be added that in practice it is necessarv 

 to sow two or three seeds in a group in order to be sure of 

 a crop. All the plants may be left, especially when the 

 object is to obtain a thick covering to prevent the growth 

 of weeds. 



In the following table the yields per hectare of green
