Where the fertilizer was applied in the drill, the borax in as small 
quantities as 1, 2, 3, and 4 pounds per acre had a retarding effect on 
the early growth of the beans, and 10 pounds of borax markedly 
stunted the plants. There was not much noticeable depression of 
growth by borax in quantities under 4 pounds, and when the bean 
vines reached maturity they had outgrown all injury. 
in section 1, 20 pounds of borax decreased the growth of vines, but 
the production of beans was not influenced by quantities under 100 
pounds per acre. In section 2, 10 pounds per acre caused marked 
depression in the final yield of both vines and beans. In the broad- 
casted section 20 pounds per acre depressed the production of beans, 
but vine growth was not influenced by quantities smaller than 50 
pounds. There was some stimulation in all sections by the smaller 
applications. 3 
EFFECT OF BORAX ON SNAP BEANS. 
_ The experiment with snap beans was similar in all details to that of 
the Lima beans. The seeds were planted on May 26, somewhat thick 
in the row and thinned to 125 per plat on June 15. They had 
matured by August 13, on which date the experiment was terminated. 
The beans were picked weekly, and the record is given in pounds of 
green beans produced. 
The snap beans proved to be very sensitive to borax. During the 
first month the plants where 1, 2, 3, 4, and 5 pounds of borax were 
applied in section 2 showed a slightly lighter color of foliage than the 
no-borax plat, although there was no distinct bleaching. There was 
a distinct and marked bleaching of leaves with 10 pounds and upward. 
This effect was distinguished by a curled leaf having yellow and brown
