The leguminous plants native to
dry-farm areas have not as yet been subjected to extensive economic
study, and in truth very little is known concerning leguminous
plants adapted to dry-farming.
In California, Colorado, and other dry-farm states the field pea has
been grown with great profit. Indeed it has been found much more
profitable than wheat production. The field bean, likewise, has been
grown successfully under dry-farm conditions, under a great variety
of climates. In Mexico and other southern climates, the native
population produce large quantities of beans upon their dry lands.
Shaw suggests that sanfoin, long famous for its service to European
agriculture, may be found to be a profitable dry-farm crop, and that
sand vetch promises to become an excellent dry-farm crop. It is very
likely, however, that many of the leguminous crops which have been
developed under conditions of abundant rainfall will be valueless on
dry-farm lands. Every year will furnish new and more complete
information on this subject. Leguminous plants will surely become
important members of the association of dry-farm crops.
