554 FORAGE PLANTS AND THEIR CULTURE 



plant will become of considerable use in southwestern 

 Kansas, western Oklahoma and northern Texas. Where 

 the rainfall is greater, comparative experiments indicate 

 that the cowpea is distinctively preferable. 



The methods employed in growing cowpeas are satis- 

 factory for the moth bean. The crop should be planted 

 in rows from 2J to 3 feet apart, with plants every 2 to 3 

 inches. This requires from 5 to 6 pounds of seed to the 

 acre. Owing to the thick mat of vines produced, the crop 

 can be easily harvested with a mower by setting the cutter 

 bar low. At least two cultivations should be given and 

 the surface soil left as smooth as possible, so as to facili- 

 tate harvesting. The crop should not be harvested 

 until it has made its maximum growth. The mass of 

 green forage can best be cured in windrows and later hauled 

 and stored without putting into cocks. 



671. Adzuki bean (Phaseolus angularis] . The adzuki 

 bean is probably native to eastern Asia, but the wild 

 plant is not known. It is extensively cultivated in Man- 

 churia, Korea and Japan, and is rarely found in the 

 hill country of northern India. In Japan about 350,000 

 acres are grown annually. It is readily distinguished 

 from the mung bean, to which it is closely related, by the 

 pods and seeds. The seeds of this species are about the 

 size of an average garden pea, but are oblong in shape, and 

 red, cream, orange or mottled in color. The pods are 

 mostly pale colored and smooth, resembling small cowpea 

 pods, while those of the mung bean are dark colored, 

 smaller, and hairy. This bean resembles an upright cowpea 

 in its habits of growth, but the stems are not as large and 

 hardly as woody. It is adapted to essentially the same 

 conditions as the soybean. 



In Japan and Manchuria the adzuki bean is grown
