||Pineapple grows on a wide range of soil types
However, the most suitable soil is a well-drained sandy loam with a high content of organic matter.
It should be at least 60cm deep with medium to by Acidity - pH of5to6.5.
||Pineapple thrives best in warm temperature 201 to 32°C at an altitude ranging from 1370 to 1740 metre above sea level.
||Prepare land early to enable planting to take place when there is adequate moisture in the soil.
Since the pineapple has a weak root system, it needs seed bed that is deeply and thoroughly cultivated.
Remove perennial weeds like couch grass by spraying with Round Up or Glyphosate - mixing about 200-250m1 per 20 litre of water in a sprayer. A similar chemical with the trade mark "MAMBA' is now also on the market.
||• The crown which is the terminal shoot at the top of the fruit.
• The sucker that develops from the aerial or underground part of the stem.
• The slip which is a shoot arising from the stalk or peduncle.
• Plant similar planting materials in one area (slip, sucker,crown).
• These could be sorted further according to uniformity of size.
• Suckers mature earliest at about 18 months, slips take about 20 months while crowns take up to 24 months
|Preparation of planting materials:
||(a) Remove the leaves 3-5cm from the bottom to encourage early rooting.
(b) Dip the plant for about 3-5 seconds in
Sumithion (Fenitrothion) 50 of the following
possible mixture to destroy mealybugs:
-30m1 per 20 litres of water
-1 5mb per 10 litres of water.
(c) Heap the treated planting material for about a week to allow the wounds to heal.
|Other soil treatments:
||Application of fertilizers is necessary to boost crop yield.
Currently three types of fertilizers are of fertilizer is necessary to boost the yield of the crop.
Three types of fertilizers are
Just before planting, to be incorporated into
the soil. CALCIUM AMMONIUM NITRATE (CAN) - 80kgper acre
SINGLE SUPER PHOSPHATE (SSP) - 80kg
MURIATE OF POTASH - 100kg per acre,
Total - 260kg.
After crop establishment 2-3 months later
(if still raining) apply CAN 80kg per acre, on
the soil surface.
Alternatively, a thick mulch of coffee husks up
to 10cm (4) can be applied to suppress weeds
and also provide nutrients as the mulch
To adequately cover a complete
acre, you may require up to four lorry loads of
Nematodes in the soil can destroy the root system of the pineapple.
Currently it is recommended to sterilize the soil using either NEMACUR or granular FURADAN.
A total of 2kgs of active ingredient is needed
Some nematicides contain 5% of the
active ingredient while others up to 10%.
Also follow the instructions of the manufacturer on the label.
|When to plant:
||Pineapple can be planted any time there is adequate moisture in the soil but the earlier the better at the start of the rainy season.
||Pineapple requires a lot of planting material depending on the spacing and size of fruit one intends to get.
(a) 60cm x 30cm x 120cm (2ft x 1 ft x 4ft) requires 14,500 planting material per acre. This spacir1g produces big fruits.
