Potato (semilha)

Original title: Semilha

Semilha is the Madeiran name for the potato (Solanum tuberosum), derived from Spanish 'semilla'. The entry covers its introduction to Madeira in 1760 and to Porto Santo after 1820, how it is cultivated, and its annual output.

Potato (semilha)

This name, given in Madeira to Solanum tuberosum, a plant of the family Solanaceae, derives from the Spanish word semilla. The word seems to have been written on a label that accompanied the first tubers brought to this island, imported from the Canary Islands, and was taken here for the name of the plant. The potato (Madeiran semilha) began to be cultivated in Madeira in 1760. It is propagated from cut pieces of its tubers, each piece having to contain a few eyes. The crop is harvested three or four months after the tubers have been planted.

Madeira produces some 25 million kilograms of potatoes (semilhas, the Madeiran word) a year, and the average yield per hectare may be reckoned at 10,000 kilograms (1921).

The potato is also grown on Porto Santo (‘holy harbour’), where it was introduced only a little after 1820.

This plant is native to the Andes, in South America, and was brought to Europe by the Spaniards shortly after the conquest of Peru. Combined with any other substance richer than itself in nitrogenous principles, it makes an excellent food for humans, and it can also be used, raw or cooked, as animal feed.
