Pineapple Cultivation

Pineapple cultivation has emerged as a highly profitable agricultural venture, providing substantial financial returns for farmers who engage in cultivating this tropical fruit. Known for its sweet flavor and versatility, pineapple is in high demand both locally and internationally, making it a lucrative crop for small-scale and commercial growers alike. With proper cultivation techniques, pest management, and post-harvest practices, pineapple farming can yield high-quality produce, ensuring economic benefits and sustainable agricultural growth. This pineapple farming guide explores the essential steps and strategies for successful pineapple farming, from planting to harvesting and beyond.

Pineapple life cycle

The pineapple life cycle spans approximately 18 to 24 months, beginning with planting the crown, sucker, or slip, followed by vegetative growth, flowering, fruiting, and eventual harvest, with the potential for ratoon crops to extend productivity. Here are the details about the pineapple life cycle:

Land Preparation

Land preparation is a crucial initial step in pineapple cultivation, laying the groundwork for successful farming and maximizing crop yields. The process begins with clearing the land of any existing vegetation, rocks, or debris, followed by the thorough removal of weeds that could compete with pineapple plants for essential nutrients and water.

Once cleared, the soil is tilled and leveled to create an optimal planting environment, ensuring proper drainage and aeration—key factors for healthy root development. Soil testing may also be conducted to assess nutrient levels and pH, enabling farmers to make necessary adjustments to achieve ideal growing conditions. Effective land preparation not only fosters robust pineapple growth but also helps mitigate pest and disease risks, making it an indispensable step in establishing a productive and profitable pineapple farm.

Soil Type for Pineapple Farming 

Sandy loam, loamy, or well-drained soils with a pH of 5.5 to 6.5 are ideal for pineapple growth because they allow for the optimum uptake of nutrients. Proper drainage keeps roots from rotting and waterlogging. Rich in organic matter and micronutrients like calcium and magnesium, fertile soils improve yield, growth, and fruit quality. Enhancing soil structure and nutrient availability can be achieved by adding manure or compost. Before planting, assess the pH of the soil and make any necessary amendments with sulfur or lime.

Climate Requirements for Pineapple Cultivation

Pineapples thrive in tropical and subtropical climates, where consistent warmth and humidity support their growth and fruit development. The ideal temperature range for successful pineapple cultivation is between 20°C and 30°C. Temperatures below 15°C can slow growth and delay fruiting, while temperatures above 35°C may cause sunburn on the fruit and reduce quality.

Moderate rainfall of about 1000 to 1500 mm annually is optimal for pineapple plants. While pineapples are drought-tolerant due to their CAM (Crassulacean Acid Metabolism) mechanism, which helps them conserve water, regular moisture is crucial during the vegetative and flowering stages to ensure healthy plant growth and maximum yield.

Pineapples are sensitive to waterlogging and excessive moisture, which can lead to root rot and fungal infections. Therefore, well-drained soil and supplemental irrigation during dry periods are necessary to maintain adequate moisture levels without oversaturating the roots.

The plant is highly susceptible to frost, which can damage leaves, halt growth, and even kill young plants. Pineapples should be grown in areas free from frost or in regions where protective measures can be taken during colder months.

Pineapples need constant sunlight all year round for the best fruit quality. While too much extreme heat without protection might harm the fruit, inadequate light can result in poor fruit development and lower sugar content.

In areas with seasonal variations, it is advisable to plant pineapples at the beginning of the rainy season to ensure adequate water availability during early growth, while supplemental irrigation may be necessary during the dry season.

Major Cultivars

The pineapple cultivation industry features a diverse range of major varieties, categorized into three primary groups.

a). Cayenne Group

This group includes well-known varieties such as Smooth Cayenne, Kew, Giant Kew, Typhones, Sarawak, Champaka, Hilo, and Charlotte. These cultivars are valued for their high productivity and are particularly suitable for processing purposes.

b) Queen Group

The Queen group features varieties like Queen, Mauritius, Ripley Queen, James Queen, Alexandra, Common Rough, and Victoria. These cultivars are celebrated for their sweet taste and compact size, making them a preferred choice for fresh consumption.

c) Spanish Group

Varieties in the Spanish group, such as Red Spanish, Singapore Spanish, Cabezona, Selengor Green, Gandol, Betek, Castilla, and Pina de Cumana, are recognized for their disease resistance and adaptability to diverse growing conditions.

Each group offers unique characteristics, enabling farmers to select cultivars that align with their specific farming goals and market requirements. This diversity ensures flexibility and caters to a wide range of consumer preferences.

Planting

Selecting superior propagation resources, such as suckers (shoots developing from the base of the plant), slips (tiny shoots sprouting from the fruit stalk), and crowns (the leafy top of the fruit), is the first step in pineapple cultivation. To guarantee good growth, these materials are planted in soil that has been prepared with due consideration for arrangement and spacing.

Making the most of available space, sunshine, and resources requires careful orchard planning. The Double Row Planting System is a popular technique that involves placing two rows of pineapple plants closely together on a single raised bed with a greater distance between the beds.

a). Spacing Details

The spacing guidelines for pineapple farming are meticulously planned to promote optimal growth and streamline farm operations. Raised beds are generally constructed to be 1 meter wide, creating a sturdy foundation for planting. On each bed, rows are positioned 45 cm apart to provide ample space for the plants to thrive without becoming overcrowded.

Within a row, individual plants are placed 30 cm apart, ensuring an ideal density that fosters healthy growth. Furthermore, a 60 cm distance is maintained between neighboring beds, enabling easy access for critical tasks like irrigation, fertilization, and harvesting. This well-thought-out spacing approach balances plant vitality with efficient farm management.

b). Planting Layout

The planting layout for pineapple cultivation involves the use of raised beds with double rows to improve drainage and prevent waterlogging, a crucial factor for maintaining pineapple health. Within these double rows, plants are arranged in a zigzag or staggered pattern to optimize space utilization and ensure even sunlight exposure, promoting balanced growth and efficient use of resources.

c). Additional Considerations

Additional considerations for pineapple cultivation include selecting the ideal planting season, which is typically during the rainy season or when irrigation is accessible, to ensure proper moisture for the plants. The planting method, whether using raised beds or flatbeds, depends on soil drainage conditions to prevent waterlogging and promote healthy growth. On average, around 17,400 plants can be cultivated per acre, though this number may vary based on the spacing and planting system employed to optimize yield and resource efficiency.

Irrigation of Pineapple

Because pineapples require consistent hydration, especially during dry seasons, effective irrigation techniques like drip or sprinkler systems are crucial for their healthy development. During the vegetative stage, each plant needs about 2-3 liters of water per week, and during flowering and fruiting, that amount rises to 3-5 liters per week. Waterlogging and root rot can be avoided with proper drainage, and mulching helps retain soil moisture and lower evaporation.

The most effective method is drip irrigation since it minimizes water loss by delivering water straight to the roots. Maintaining soil moisture levels between 50 and 70 percent of the field’s capacity is advised, and irrigation should be adjusted seasonally, rising in hotter months and falling in rainier ones. Because pineapples are sensitive to too much moisture, overwatering can harm the roots and have a detrimental effect on the health of the plant.

Irrigation Schedule for Pineapple Based on Growth Stage

Fertilizer and Manure for Pineapple

For optimum growth and yield, pineapple plants require a balanced supply of potassium, phosphorus, and nitrogen. Compost and farmyard manure are examples of organic fertilizers that increase soil fertility and offer long-term sustenance. Pineapples are nutrient-demanding crops that need careful fertilization.

Because of its effective absorption, ammonium sulfate is a preferred source of nitrogen. Using inorganic fertilizers excessively can damage soil health, contaminate water, raise expenses, and reduce profitability. For pineapple farming to be successful over the long run, a sustainable, balanced fertilization strategy is essential.

Pest and Disease

Common pests include mealybugs and nematodes, while diseases like root rot and wilt can affect yield. Regular monitoring and integrated pest management (IPM) are essential.

Pests in Pineapple Cultivation

a). Mealy Bug

Sap-sucking pests cause wilting, chlorosis, and fruit rot, with ants aiding in the dispersal of mealybugs, whose honeydew secretion disrupts plant food production. Infested fruits develop a white, waxy coating, rendering them unmarketable, while affected leaves turn pale green or yellow with brown tips, and wilting begins at the leaf edges. Severe infestations lead to rapid wilting with yellow or red leaves, whereas mild infestations result in slow wilting due to root damage.

Management

Natural enemies include parasitoids such as Anagyrus ananatis and Anagyrus kamali, as well as predators like ants, Cryptolaemus montrouzieri, lacewings, spiders, dragonflies, praying mantises, and others.

b). Pineapple Scale

Scale insects have three life stages (egg, immature, adult) and can complete several generations annually.

Damage Symptoms

Rust-colored spots appear on infested plants. The insect hides beneath a waxy secretion and molted skin, making early-stage control critical. Severe infestations can encrust plant tissues entirely.

Management

Natural enemies include parasitoids such as Aphytis chrysomphali, Encarsia citrinus, and Encarsia perniciosi, as well as predators like Rhyzobius lophanthae, Chilocoris infernalis, Pharoscymnus flexibilis, Telsimia nitida, and predatory thrips.

c). Pineapple fruit borer

One of the main pests of pineapple is thought to be the pineapple fruit borer. Uneven fruit development and holes are caused by the larvae boring into the fruit. Although damage from this insect varies widely, it can reach over 90%, and borer attacks appear to be more common in dry climes. Fruit borer assaults typically take place during fruit production and flowering, though they can also attack slips and infrequently mine leaves.

Damage symptoms

The fruit borer larvae create galleries within the pulp, causing an oozing known as “gummosis” on the fruit’s outer surface, and the resulting insect damage often leads to the rejection of the product at the packing plant.

Management

Natural enemies of the pineapple fruit borer include a variety of predators such as the mirid bug (Dicyphus hesperus), reduviid bug, big-eyed bugs (Geocoris sp.), rove beetle, dragonfly, damselfly, spider, robber fly, praying mantis, red ants, lacewings, and others.

d). Pineapple Fruit Fly

Damage symptoms

Pineapple fruit fly primarily infests fruits, causing damage when the female punctures the fruit skin with her sharp ovipositor, allowing bacteria to enter and initiate decay. Larvae hatch from the eggs and feed on the decaying tissue, as well as the bacteria and yeasts that proliferate, while also burrowing into the pineapple.

Management

Management of fruit flies involves using baited traps, such as pheromone or attractant-based traps, to monitor and reduce adult populations, along with applying netting or bagging to protect fruits from infestation.

e). Pineapple Weevil

The life cycle of pineapple weevil completed within 3 – 4 months

Damage symptoms

The entire life cycle of the weevil occurs within the same plant. Females lay single eggs in slits they create on plant leaves, and the larvae burrow into the stem, forming tunnels. Larvae pupate in the central stem, where they create a cocoon for development, and if sufficient plant tissue remains, adults emerge on the same host plant. Infestation results in the exudation of a gelatinous material that protects the weevil slits, causing damage such as feeding marks on leaves, browning of foliage, and decomposition at the base of central leaves.

Management

Mechanical control of pineapple weevil involves handpicking to manually collect and destroy adult weevils and larvae, as well as using physical barriers or trenches around fields to prevent their movement, while biological control strategies include encouraging natural predators like ants, beetles, and parasitoids that feed on weevil eggs, larvae, or adults, and applying entomopathogenic fungi such as Beauveria bassiana to target weevil populations.

Diseases in Pineapple Cultivation

a). Phytophthora heart rot

Phytophthora heart rot, caused by the pathogen Phytophthora cinnamomi, primarily affects the central leaves of pineapple plants, leading to browning and eventual death of these leaves. The disease thrives in wet, poorly drained soils, and infection often begins at the base of the plant, spreading upward to the heart (central growing point). Symptoms include a soft, water-soaked appearance in the affected tissues, followed by a foul odor as the rot progresses. Management strategies include improving soil drainage, avoiding waterlogging, and applying fungicides to prevent and control the spread of the disease.

b). Fusarium wilt

Another terrible disease that affects pineapple plants is Fusarium wilt, which is brought on by Fusarium guttiforme and is characterized by the yellowing and wilting of leaves that ultimately results in plant death. By invading the plant’s vascular system, the fungus prevents the movement of nutrients and water. Stunted growth and reddish-brown staining of the interior leaves are common symptoms of infected plants. Contaminated soil and diseased plant debris are the main ways that the disease spreads. Utilizing crop rotation, disease-free planting material, and soil fumigation to lessen the pathogen’s presence in the field are all examples of effective management.

c). Root rot

A common disease in pineapple farming, especially in soils that are wet or poorly drained, is root rot, which is brought on by fungi like Phytophthora and Pythium. These fungi target the root system, impairing the plant’s capacity to take up nutrients and water, causing wilting, leaf yellowing, and ultimately plant death. A discernible decrease in root mass is often accompanied by the appearance of brown, mushy, and decaying roots. Wet circumstances are ideal for the disease’s growth, thus effective water management is essential to prevention.

It is crucial to prevent overwatering and enhance soil drainage in order to control root rot. Planting in well-drained soils or raised beds can greatly lower the danger of infection. The application of soil treatments and fungicides can also aid in limiting the infections’ ability to spread. To reduce the effects of root rot and preserve healthy plant growth, other useful tactics include employing crop rotation and disease-resistant pineapple cultivars.

d). Black rot

Black rot, caused by the fungus Ceratocystis paradoxa, is a significant post-harvest disease that primarily affects pineapple fruits, particularly during storage and transportation. The infection often begins at wounds or injuries on the fruit surface, where the fungus enters and spreads rapidly. Infected fruits develop dark brown to black lesions, which gradually soften and decay, emitting a foul odor. The rot can spread to adjacent fruits, leading to significant economic losses as the affected produce becomes unmarketable.

To manage black rot, it is crucial to handle fruits carefully during harvesting and packing to minimize physical damage. Proper sanitation of storage facilities and equipment can also help reduce the risk of contamination. Post-harvest treatments, such as fungicide applications and controlled atmosphere storage, can be effective in preventing the spread of the disease. Additionally, ensuring that fruits are stored in cool, dry conditions and avoiding prolonged storage periods can help mitigate the impact of black rot on pineapple quality and shelf life.

Harvesting and Yield 

Pineapple plants usually flower 12–15 months after planting, and depending on the variety, planting time, plant material, and temperature, the fruits are available for harvest 15–18 months later. With fruits mature roughly five months after blossoming, natural harvesting takes place from May to August. Ethrel (100 ppm) is sprayed one month prior to the flowering season to guarantee consistent flowering.

Table-use fruits are allowed to turn golden yellow, while canning fruits are picked when there are only minor alterations at the root. The plant can be kept as a ratoon crop for three to four years after harvest, though fruit weight and yield drop in succeeding ratoons. Average yields, depending on cultivation methods and spacing, range from 50 to 80 tonnes/ha.

Grading

Grading is a crucial step in post-harvest handling to ensure that pineapple fruits meet quality standards for marketability and processing. Fruits are sorted and categorized based on specific criteria such as weight, size, and color. Uniformity in these attributes is essential for both aesthetic appeal and functional purposes, such as canning or fresh consumption. Larger, well-colored fruits are often preferred for table purposes, while smaller or slightly blemished fruits may be directed toward processing. Proper grading helps maintain consistency, enhances consumer satisfaction, and maximizes the economic value of the harvest

Storage

Harvested pineapples must be stored properly to preserve their quality and self-life. Under normal circumstances, fruits with their crowns intact can be preserved for ten to fifteen days without suffering any serious damage. However, to slow down the ripening process and avoid spoiling, refrigerated shipping is required for long-distance shipment or prolonged storage.

When stored between 10 and 13 degrees Celsius, pineapples can last up to 20 days. It is advised to maintain 7.2°C and 80–90% relative humidity for the best storage conditions. The fruit is delivered to customers or processing facilities in optimal condition thanks to these carefully regulated conditions, which also assist in maintaining the fruit’s flavor, texture, and freshness.

Packing

Proper pineapple packing is essential to prevent damage during transport and ensure quality. For local markets, pineapples are packed upright in bamboo baskets (20-25 kg) lined with paddy straw, with a second layer placed on the crowns. For distant markets, each fruit is individually wrapped in paddy straw to prevent bruising, maintaining freshness and enhancing market value.
