The development Of dry-farmlng Ii
the semi-arid southwest has created q
need for a ieguminous crop which
used In rotation with grain or forage
planting, will maintain the nitrogen
and humus content OF the soil and al
the same time provide money return
which is sure and profitable. No croI
so well fills this demand as the grow
Ing OF dry shell beans. Being a coun
trywide food-staple they have a steady
market which is little Influenced by
local conditions other than transpor
tation charges.
Varieties Of beans originating in the
humid sections of the East are OF but

Southwest. They do not Withstand

others. The results OF investigations
with these varieties BY members OF
the Arizona experiment station staff

Like other cultivated plants, how
ever, the tepary has responded to do

number Of distinct varieties. The

more than forty different types which

these, the varieties most commonly
grown among the Indians are the

designated white teparies and yellow
