Where does the potato come from?The potato is native to South America, and if found spontaneously in the Andes and Chile, it was the Spanish who first brought it back from South America in the 16th century . It is to Parmentier that we owe the culture of the potato in France. This little plump has saved us many famines in the past.
Among all the varieties offered, how to choose?It is possible to choose a variety for its yield, for its precocity, its resistance to mildew, its shelf life, and finally, and it is often the case, because it lends itself better to such or such culinary use. (taste, firmness, resistance to cooking). In general, try to choose different varieties so as to spread the harvest over a longer period and take advantage of varied flavors.
What is the yield of the potato?There is no standard yield. The yield depends on the variety chosen, the fertility of the soil and the vagaries of the weather! Potatoes can be classified according to their yield compared to a reference variety. For the variety "Bintje" often cited as a reference, you can harvest up to 1 kilogram of succulent flesh in prosperous years!
What are the diseases that threaten the potato and how can it be prevented?The varieties of potatoes we know are all relatively new. The degeneration of potatoes over time is no longer to be proven. Viruses and diseases are transmitted from year to year, weakening yields and resistance to disease. This is why there are constantly crossovers and new references. Downy mildew, a disease characterized by microscopic fungi caused by excessive humidity and recurrent heat, is the main danger facing the potato. There is not much to do in prevention, except to space the plants as much as possible and uproot immediately the affected subjects and then burn them.
Another enemy of the potato, the Colorado potato beetle and its larvae which gnaws the foliage, causing the reduction of the size of the tubers and therefore a loss of yield. If the attack has started, the most environmentally friendly and inexpensive solution is to remove the larvae and specimens manually every day. You can also choose to spray pyrethrum on the larvae before they sink into the ground. We can also cite scabies, rhizoctonia, filosity, decay to which are added ringworm, the caterpillar of the sphinx, hepial. Certainly, the potato has no shortage of enemies! Note that the potato should never be planted two consecutive years in the same place: the soil has become depleted and the possible remains of uncollected potatoes can promote the appearance of diseases the following year. Think of the Colorado potato beetles that have taken up residence in the area while waiting for the next harvest ...
