Plums, currants, and gooseberries have all been successful. Grapes
grow and yield well in many dry-farm districts, especially along the
warm foothills of the Great Basin. Tree growing on dry-farm lands is
not yet well established and, therefore, should be undertaken with
great care. Varieties accustomed to the climatic environment should
be chosen, and the principles outlined in the preceding pages should
be carefully used.
Potatoes
In recent years, potatoes have become one of the best dry-farm
crops. Almost wherever tried on lands under a rainfall of twelve
inches or more potatoes have given comparatively large yields.
To-day, the growing of dry-farm potatoes is becoming an important
industry. The principles of light seeding and thorough cultivation
are indispensable for success. Potatoes are well adapted for use in
rotations, where summer fallowing is not thought desirable.
Macdonald enumerates the following as the best varieties at present
used on dry-farms: Ohio, Mammoth, Pearl, Rural New Yorker, and
Burbank.
Miscellaneous
A further list of dry-farm crops would include representatives of
nearly all economic plants, most of them tried in small quantity in
various localities.
