PHASEOLUS HELVOLUS (aMBERIQUE) 



143 



When planted between the rows at the Agronomic Station 

 it developed remarkably well without damaging the canes in 

 anv wav. Restilts have been obtained from several varieties, 

 but the yellow has given most satisfaction. 



The green variety is very early, but remains short; its 

 seeds mature before those of any of the cow peas. Its 

 slender stalks bear less foliage, and its yield on the fields, 

 both in seeds and forage, is considerably less. 



The yellow variety is a plant which is partictilarly well 

 adapted to a mixed cultivation. Its stems are nearly straight 

 and spread ver\- little horizontally, and it can grow without 

 disturbing the young canes at all. It is sown under similar 

 conditions to the cow pea, but more closel}- if the ground 

 is to be covered rapidly. The c}'lindrical pods are, on the 

 average, only 7*5 cm. long b}' 4 to 5 mm. broad. The 

 seeds are generally eight in number; 100 grm. contain 2,855, 

 100 seeds weighing 3 to 4 grm. 



Appended are the results of trials made at the Agronomic 

 Station and published in the Annual Report for igio : —

On comparing the mineral matter of amberiques with 

 those of cow peas the proportion of the different elements is 

 scarcely seen to dififer at all, but when correlated to the crop 

 per hectare a much lower total of mineral matters is found, 

 the returns to the soil being much less by weight relative 

 to the green crop.
