It seems natural to me that the Olluco/Ulluco (Ullucus tuberosus) and the "papalisa" page be merged somehow. Alas, the product has a common name that varies depending on the region/county that uses it, so perhaps a Latin taxonomy should be the header. Of course, for my own motives, I would love to see the Peruvian name prevail, yet if it is in fact the same product known in other countries (such as apparently Colombia) by a different name patriotism need be set aside in the interest of making the unified page useful to global wikipedia gourmands. Furthermore, I think a discussion/investigation would be useful if it really should becalled a potato, for my part (based on conversation with agronomists and my cook) I feel it should not be, but greater minds might prevail....

I don't see that the page currently says that is it a potato, only that it is "like" a potato. I agree that it should be merged with papalisa, and probably titled with the scientific name, given the diversity of common names.

Also, there are two images in Wikimedia that were mis-identified as oca, but are actually Ulluco. I expect they should be re-labeled prior to linking them to this page, but I'm too new at this to know if anyone than the person who uploaded the images can do that. It would be nice to have those images linked to this page, instead of to the oca page. Api11aYacheq (talk) 04:42, 24 December 2009 (UTC)[reply]

Additional information

Dear users!

Here is my suggestion to improve the Ulluco article. I added some sentences where there was already information and added the subchapters nutritional value, cultivation and pests and diseases.

Sentences I added in the introduction part:

Ulluco is an erect and compact plant which is 20-50 cm high. Its tubers vary in shape and color. The tubers can take every shape between spherical and cylindrical. The colors are manifold and can be white, light green, pink, orange and purple. ^[1]

The name Ulluco stems from the Quechua word ulluko, where ullu means male organ.^[2]

Nutritional value

Ulluco is known to contain high levels of protein, calcium, and carotene. The tuber is also a good source of carbohydrates. Fresh ulluco contains about 85% water, 15% sugars and starches, 1-2% proteins, wherease the protein content varies considerably. Up to 15% of proteins in dry weight have been reported. The unusually high vitamin C content of Ulluco (23mg/100g fresh weight) has also to be mentioned.^[3]

Cultivation

Ulluco is cultivated at the high altitudes (2'400-4'000 m) of the Andes from Venezuela to Argentina, where daylengths don't exceed 10-13.5 hours. Ulluco is drought and cold resistant and well adapted to the predominant marginal soils. But the plant is also grown at sea level in Canada, England and Finland. ^[3]

The crop is cultivated in a similar way to potato,

mashua. Parts of the tuber or the shoot can be planted directly into the soil. No hormons or other treatments are necessary. A temperature of above 18 °C is ideal for the growth.^[3]

The tubers are planted in furrows with row spacing of 80-100 cm and distance of 40-50 cm. The planting density is recommended to be 450-675 kg/ha depending on the size of the tubers. Ulluco is normally planted during the rainy season and followed by potato as ullucos have a long vegetative period,^{beans.
It is not common to use fertilizer. Farmers however, sometimes add manure and harvest leftovers to improve the fertility of the soils. Between 6 and 12 t/ha are seen as a good dose.}[4] The yield average is between 5 and 9 t/ha. ^[3]

Pests and diseases

Ulluco has few pest and disease problems. But it has been shown that the tubers are generally infected by viruses which decreases yield. Potential yield of virus free plants could be 30-50% more. ^[3]

May 2015 Edits

I'm going to take a crack at improving this page. I'll make a series of small edits so that individual changes can be rolled back easily.

Names

The name of the page is ullucus, which is the name of the genus, but not really a common name for the plant. The common name currently preferred in the article is ulluku, but I don't think you'll find any sources in English that use that name. Ulluco is standard in English, probably followed by olluco. I'm changing the name in the article. The page should probably also be renamed "Ullucus tuberosus," instead of just "Ullucus."Gdasein (talk) 07:56, 11 May 2015 (UTC)[reply]
