Except in the case of pineapple cultivation in greenhouses, this type of planting is usually in principle between 30° north and 25° south of the equator in temperatures ranging from 18° C to 35° C and in sandy or clay soils gravillonaires showing a pH of 4.5 to 6.5. Altitude varies depending on the place of production and the type of pineapple grown. Pineapple is a fruit that does not require much water. Rainfall between 650mm and 2500mm per year is sufficient depending on the type of fruit grown, the place of production and humidity levels should, in principle, be 70% to 80%. Pineapple support fairly drought, but needs a well-drained if significant rainfall ground. Regarding the cold, a passage by freezing temperatures (-2° C) is possible, but it should be short so as not to cause stunting or give the fruit a sour taste.
Reproduction of pineapple is not done by seed, but replanting the entire crown in the soil or by making cuttings. Pineapple is a fruit that can repel consecutive years, however, for performance issues (the fruit tends to become smaller and as the years), farmers often replant new plants between two and five regrowth. Generally, pineapples are harvested by hand leaving a portion of the stalk in the soil. The fruits can also be easily separated by cutting the plant, however, this causes a risk of infection, penetrating through the wound left by the cut and spread in the fruit pulp. It may be the cause of other parasitic or fungal attack. In large farms, harvesting can be done mechanically using a combine harvester. This type of equipment can be harvested between 20 and 25 grooves per pass.
Pineapple is grown in tight rows with a density of 60,000 plants per hectare on average. This number may, however, be greater, in particular in the case of smaller fruit. Pineapples produce in principle for four years because their performance tends to decline thereafter. Most major producers of pineapples are within the same range that goes from 10 to 30 tons per hectare, except Costa Rica poster from the late 1980s, a very strong increase in yields increased from 17 tons per hectare in 1988 to nearly 73 tons per hectare in 2001.
Pests and Diseases
In the case of pineapple, in addition to diseases and pests, the farmer must pay attention to the proliferation of weeds in his case can be extremely destructive. According to the agricultural Larousse: "It is estimated that the cost of this fight atteint10% of the overall cost of production".
If a minimum their care is provided, pineapples are sensitive to a small number of diseases and pests. The most common pests of pineapple plants are mealy bugs and mites. All can be removed by spraying a soapy solution or an insecticide on the plant. The most common plant disease pineapple heart rot, is causing a disease caused by a fungus and can be combated with a fungicide. In case of successful treatment, a new shoot (which will eventually give birth to a fruit) will emerge.
