The potato is a herbaceous plant that belongs to the family of the Solenaceae, originating from Perщ, Bolivia, Mexico and Chile. The plant was cultivated in these areas before being brought to Europe, its origin is unknown, since moment that there are no spontaneous species. The edible part of the plant is represented by the tuber, the swelling of the terminal part of the plant that develops underground following the accumulation of carbohydrates that serve as a reserve for the plant. The leaves have smooth or serrated edges. The stems vary their height between 60 and 150 cm, the flowers present colors between yellow and silver, while the fruits are yellowish berries. The presence in the fruit of solanine, an alkaloid, makes it poisonous, in the other parts of the plant the concentration is lower.
Better conditions for potato cultivation
The potato is a plant that certainly prefers the areas with a climate characterized by very cold winters, but with mild temperatures in the rest of the year. Needing a lot of water, the best areas for potato cultivation would be those in the mountains that have long winters and short, cool summers. The ideal soil for cultivation must be light, absolutely fertile (in fact it must be prepared a few months before planting with adequate fertilization), presenting optimal drainage and good digging. The soil must necessarily be dug at a depth of about 30-35 cm, in the furrow a good quantity of mature manure should be laid in order to be able to adequately fertilize the soil involved in cultivation.
