Cultivation details                                         
Succeeds in most soils[1]. Dislikes wet or heavy clay soils[16, 37]. Prefers a slightly acid soil, the tubers are subject to scab on limy soils or those deficient in humus. Yields best on a fertile soil rich in organic matter. This plant is one of the S. American species of potatoes. It is not frost hardy but can probably be grown in much the same way as potatoes are grown by planting out the tubers in spring and harvesting in the autumn[K]. Plants might have strict daylength requirements and may yield poorly in temperate zones because they need short-days in order to induce tuber-formation[196]. This species is commonly cultivated for its edible tubers in S. America[196]. Yields are often low but 30 tonnes per hectare have been recorded[196]. Plants are susceptible to late blight[196]. This species is the immediate ancestor of the potato of commerce, S. tuberosum, though the tubers look rather different[196]. A tetraploid species, probably derived from S. stenotomum by chromosome doubling or by hybridization with S. sparsipilum, it produces fertile seed[196].
                                                                                 
Propagation                                         
Seed - sow early spring in a warm greenhouse. Prick out the seedlings into a fairly rich compost as soon as they are large enough to handle and grow them on fast. Plant them out after the last expected frosts. Division. Harvest the tubers in autumn after the top-growth has been cut back by frost. Store the tubers in a cool frost-free place overwinter and replant in April.

  [K] Ken Fern Notes from observations, tasting etc at Plants For A Future and on field trips.

[1]F. Chittendon. RHS Dictionary of Plants plus Supplement. 1956
Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[16]Simons. New Vegetable Growers Handbook.
A good guide to growing vegetables in temperate areas, not entirely organic.
[37]Thompson. B. The Gardener's Assistant.
Excellent general but extensive guide to gardening practices in the 19th century. A very good section on fruits and vegetables with many little known species.
[46]Uphof. J. C. Th. Dictionary of Economic Plants.
An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[105]Tanaka. T. Tanaka's Cyclopaedia of Edible Plants of the World.
The most comprehensive guide to edible plants I've come across. Only the briefest entry for each species, though, and some of the entries are more than a little dubious. Not for the casual reader.
[177]Kunkel. G. Plants for Human Consumption.
An excellent book for the dedicated. A comprehensive listing of latin names with a brief list of edible parts.
[196]Popenoe. H. et al Lost Crops of the Incas
An excellent book. Very readable, with lots of information and good pictures of some lesser known food plants of S. America.

Can you tell me if using potato juice drops in the eyes is safe? I was told my son would need atropine drops in his eye for regular treatment for a lazy eye, but I'm worried about it. I would rather a natural solution. I heard that the same ingredient is contain in the potato and tomatoes - are they safe to put in the eye or could they cause blindness?

hmmm.this could probably be a big help for the preparation of my investigatory project,because i have read that there are still so many uses of potato aside from an engridient to our food..
