Pineapple

Pineapple is grown as a long-lived herbaceous perennial, with individual plants remaining productive across a plant crop and one or more ratoon crops before a field is replanted with fresh propagating material. Its rosette growth habit, characteristic of the bromeliad family, stores water and nutrients in thick, strap-like leaves.

Because propagation is entirely vegetative, planting material quality and type strongly influence field uniformity and the timing of subsequent harvests. Commercial production ranges from smallholder plots to large plantation systems using uniform planting material and, in many operations, chemically induced flowering.

Family

Bromeliaceae (bromeliad family)

Genus

Ananas

Principal species

Ananas comosus (cultivated pineapple)

Growth habit

Herbaceous perennial forming a low rosette of stiff, strap-shaped leaves around a central stem, characteristic of the bromeliad family; the fruit is a compound (multiple) fruit formed from fused individual flowers

Pineapple originated in South America, where wild and semi-domesticated Ananas relatives are found, and was carried by indigenous peoples throughout the tropics of the Americas well before European contact. It subsequently spread through global trade to become a major tropical fruit crop grown across suitable regions of Asia, Africa, and Latin America.

Production volumes, leading cultivars, and trading patterns shift over time and by region; current figures are best obtained from primary sources such as FAOSTAT and national agricultural statistics services rather than assumed.

Pineapple is adapted to tropical and warm subtropical climates and is intolerant of frost, which can severely damage or kill plants. It tolerates a range of rainfall conditions but performs best with consistent moisture and warmth throughout its growth cycle.

Because pineapple grows over a long, multi-year cycle spanning a plant crop and ratoon crops, cumulative climate conditions across that period, rather than a single season, shape overall field performance.

Pineapple is grown across a range of soils but performs best on deep, well-drained, aerated soils such as sandy loams and lateritic soils, both widely used in major production regions. The crop is notably intolerant of waterlogging, which quickly leads to root decline.

Pineapple fields are established using vegetative propagating material rather than seed, since seed-grown plants are variable and slow to reach a productive size. Growers select among crowns, slips, and suckers depending on availability, uniformity needs, and time to first harvest.

• Selection of propagating material — crowns, slips, or suckers — based on availability and desired uniformity
• Field spacing and planting density set according to cultivar and the propagating material used
• Management of the plant crop (the first harvest from newly planted material) followed by one or more ratoon crops from the same base plants
• Use of ethylene-generating treatments, natural or applied, to induce more uniform and synchronized flowering across a field

Nitrogen and potassium are both important to pineapple growth and fruit development, with potassium closely linked to fruit quality. Boron is a micronutrient of particular relevance to pineapple, since deficiency can affect fruit and plant development.

Pineapple is grown both under rain-fed conditions in humid tropical areas and with supplemental irrigation in drier regions. Drip irrigation is used in many commercial operations to deliver water efficiently to the root zone while limiting the risk of waterlogging.

Because the crop spans a long multi-year cycle, water management needs to account for the differing demands of establishment, vegetative growth, flower induction, and fruit development phases.

Root rot, associated with poorly drained or waterlogged soils, is a serious concern for pineapple given the crop’s strong intolerance of excess soil moisture. Fusariosis, caused by Fusarium guttiforme, is a major disease of pineapple in the Americas, affecting fruit and stems and capable of significant crop loss where susceptible cultivars are grown.

Mealybugs are a particularly important pest group in pineapple because certain species are associated with a wilt disease complex: mealybug feeding, combined with an associated virus, can cause a decline known as mealybug wilt, making mealybug management a disease-prevention measure as well as direct pest control. Scale insects are also common pests, affecting plant vigor and fruit appearance.

Management combines clean, disease-free propagating material, field sanitation, drainage management, monitoring, and — where justified — locally authorized control products applied according to their labels.

Pineapple fruit is harvested by hand once it reaches a suitable maturity, assessed through indicators such as skin color change and fruit firmness, since the crop’s long, variable growth cycle makes a universal days-to-harvest figure unreliable across cultivars and regions. Fruit intended for fresh markets is often picked at a different maturity stage than fruit destined for processing.

• Fresh-market whole and cut fruit
• Canned pineapple and pineapple juice
• Dried and other processed pineapple products
• Fiber and by-products from leaves and processing waste in some production systems
