Humidity : Humidity is very low, while the evapora
tion goes on very actively, particularly in spring, as already
hinted. The evaporation in the germinating period in
spring, together with dearth of rain, from a standpoint of
Bean cultivation, can not act favourably upon the germination
 and growth. However, the large evaporation in
summer and autumn makes excellently for the growth and
ripening of the Beans.
Especially at the havesting time in autumn, ample
evaporation tends to perfect the drying of the Beans to
befit them better for long storage and to enhance the

yualitv.

(2) MaxcHURIAN Soin & Bean Crops

The soil best suited to Bean cultivation is loamy clay.
clay, loam. and sandy loam in the order mentioned. While,
as to the relation between the ingredients of the soil and
the Bean crops, no definite conclusion is yet available.
Beans like other leguminous plants, appear to get the
nitrogen needed for the growth principally through symbiotic
 action with bacilli radicicola, and little thereof is absorbed
 directly from the soil. Therefore, the amount of
nitrogen ingredients contained in the soil has less effect
upon the Beans than on any other species of plants. A
soil possessed of the qualities suited for the propagation of
baeili radicicola is generally of smaller grain having a strong
