High Density Avocado Plantation

What is High Density Avocado Plantation?

High-Density Avocado Plantation is a modern farming technique that involves planting avocado trees at higher densities than traditional methods. Instead of spacing trees far apart, they are planted closer together, resulting in more trees per acre. This technique maximizes land utilization and increases overall yield, ultimately boosting profitability for avocado farmers.

Benefits of High-Density Avocado Plantation

  1. Reach full production earlier: With high-density planting, avocado trees can achieve full production sooner. Fruit production typically begins in the third year, and maximum productivity is reached by the fifth or sixth year.
  2. Trees well sheltered: High-density avocado plantations provide better shelter for small trees than conventional spacing. This results in the creation of microclimates, improving fruit quality and yield.
  3. Self-mulching: In high-density plantations, small trees self-mulch at an earlier stage. Mulch layer, promoting healthier tree growth and more efficient nutrient absorption.
  4. Improved tree health: Regular pruning in high-density plantations helps maintain a balanced root-to-shoot ratio, improving overall tree health.
  5. Better fruit size: High-density planting encourages healthier trees with robust canopies and root systems, resulting in improved fruit size.
  6. Land utilization: High-density avocado plantations allow planting on steeper land since machinery access is less crucial than in conventional plantations.
  7. Reduced harvest costs: High-density planting enables ground-level harvesting, significantly reducing the associated costs. There is no need for expensive cherry picker machinery or skilled labor.
  8. Minimize health and safety risks: High-density plantations offer advantages in terms of health and safety by reducing the reliance on risky cherry picker work and minimizing potential accidents.
  9. Reduced soil compaction: Without cherry pickers and smaller sprayers, high-density plantations experience reduced soil compaction, leading to better soil health and structure.
  10. Less pest and disease damage: The compact canopy of high-density avocado plantations allows for better spray penetration, resulting in fewer insect infestations and more effective fungicide application.
  11. Less fruit staining: Strong and vigorous canopies maintained in high-density plantations help minimize fruit staining, ensuring higher fruit quality and market appeal.

High-Density Avocado Plantation Techniques

The trend of planting fruit tree crops more intensively has been observed worldwide, including among avocado growers in New Zealand. Traditionally, avocado plantations were spaced at 7 meters by 7 meters, resulting in approximately 200 trees per hectare. However, high-density plantings have gained popularity, with spacing options ranging from 6 meters by 4 meters (416 trees per hectare) to 5 meters by 3 meters (666 trees per hectare).

Some experimental plantations have even pushed the limits with spacings as close as 2.5 meters by 2.5 meters, accommodating up to 1600 trees per hectare. These techniques allow for maximizing land utilization and achieving higher yields in avocado farming.

Sustainable and Best Practices for High-Density Avocado Plantations

Avocados (Persia americana) are nutritious tropical fruits from Mexico and Central America. Jamaica, Spain, Zanzibar, Florida, and California received it. Early 19th century India brought it. Avocados are abundant in protein (4%), healthy fats (30%), and low in carbs. Avocado oil, like olive oil, is used in cosmetics. Avocados have 245 cal/100 g and several vitamins and minerals. Copper, iron, and potassium—essential for antioxidant enzymes and blood pressure—are abundant in the fruit.

Avocados contain all essential amino acids and have been shown to promote good cholesterol while reducing bad cholesterol levels. Avocado is commonly used fresh in sandwiches, salads, ice creams, and milkshakes. The pulp can also be preserved by freezing. The peel extracts of immature fruits of the Green cultivar have been found to contain three antifungal compounds. Avocado’s caloric value ranges from 1500 to 2250 calories per kilogram, and its protein content is three times that of an apple, nearly equal to that of a local plantain, and less than olive fruit.

Avocado cultivation has a historical background in India. American missionaries introduced avocados to Bangalore between 1906 and 1914, and further propagation for commercial purposes began in the 1940s. Avocado orchards were established in regions like Kallar near Nilgris, Palni, Kodaikanal, Yercaud, Coorg, and British bungalows. With the influx of Americans during World War II, interest in avocado propagation increased.

The Government of Mysore opened a research station for non-citrus fruits in Hessaraghatta, Bangalore, where different avocado seedlings were introduced. Avocado cultivation gained popularity in the last decade due to its nutritional properties. Avocado production is concentrated in Central and South American countries, with Mexico being the largest producer and exporter. Other major producers include Chile, Indonesia, the United States, Dominican Republic, Colombia, Brazil, and Peru.

Avocado production in Asia is limited, with countries like China, Vietnam, and Korea cultivating the fruit. Mexico give 45 percent of the international avocado market, which continues to grow globally. Avocado production in India is currently limited and needs to be better organized. However, the agro-climatic conditions in various parts of the country favor expanding avocado cultivation. Avocado is grown in southern tropical states like Tamil Nadu, Kerala, Karnataka, Maharashtra, and the northeastern Himalayan state of Sikkim.

Avocado Farming

Avocados require specific soil and climate conditions to thrive. They are intolerant to northern India’s hot, dry winds and frosts and are typically grown in tropical or subtropical areas with summer rainfall and humid subtropical summer rainfall areas. Avocados are sensitive to poor drainage and cannot withstand water-logging. They are also intolerant to saline conditions, and the pH range is from 5 to 7.

Varieties: Avocado cultivation in India involves the West Indian, Guatemalan, and Mexican races. West Indian-Guatemalan hybrids are preferred in tropical areas, while Guatemalan-Mexican hybrids thrive in less tropical regions. In Sikkim, both Mexican and Guatemalan races are successful. Some notable avocado varieties worldwide include Hass, Fuerte, Gwen, Bacon, Zutano, Reed, and Pinkerton. India has promising varieties like Green Type, Purple, TKD-1, Nabal, Linda, Puyevla, Gott-Froid, Furerte, Pullock, and Waldin. These varieties differ in fruit size, skin texture, oil content, and flavor.

Propagation: Avocado propagation uses seeds. Avocado seeds only last 2–3 weeks. Dry peat or sand at 50°C improves seed viability. To speed germination, remove the seed coat before sowing. Most Indian avocado trees are seedlings, which take longer to fruit and vary in output and quality.

Avocado seedlings are highly variable due to cross-pollination, making them difficult to breed for commercial orchards. Budding or grafting superior avocado clones is necessary to resolve these challenges. Indian research found that September and March cleft grafting had the highest success rates and best development.

Field Preparation and Planting: Choose A and B group varieties with overlapping flowering times. A/B group varieties should be 1:1 or 2:1. Avocado trees are planted 6 to 12 meters apart, depending on their vigor and growth pattern. Fuerte needs more space. Avocados should be planted on mounds in wet locations.

Sikkim prefers a planting distance of 10 x 10 meters on steep slopes, while southern India prefers 6–12 meters, especially for coffee. One cubic meter of planting pits in April-May is dug and filled with farmyard manure and dirt. Planting should be done in June-July or September. Avocado trees are grown with coffee in some areas.

Nutrient Management: Avocado trees need balanced nitrogen, phosphorus, and potassium manure. Young trees need 1:1:1, while mature trees need 2:1:2. When soil pH surpasses 7, iron chelate can fix the iron shortage. Iron, zinc, and boron help trees grow, absorb nutrients, and yield. Avocados require integrated nutrient management with inorganic fertilizers and organic manure.

Fertilizers should be sprayed twice, in May-June and September-October, in humid tropical locations like Coorg and Karnataka, Kerala, and Tamil Nadu. Fertilizer use in Northern India follows the monsoon season, March–April and September–October. Apply zinc sulfate (0.5%) and other micronutrients foliar in April-May or September-October.

Training and Pruning: Avocado plants need early light pruning to open their central canopy. Unless necessary, subsequent pruning is infrequent. To regulate tree size, upright species may need top pruning, while spreading varieties may benefit from branch thinning and shortening. For cultural activities, pruning removes dropping or ground-touching branches. Overpruning can increase vegetative growth and lower yield.

Irrigation: In India, avocados are cultivated in locations with high and consistent rainfall. Thus, avocado trees are usually grown without watering. Every three to four weeks in dry months, Irrigation helps prevent moisture stress. Sprinkler watering increases avocado fruit size, oil %, and harvesting time. However, flooding promotes root rot. Mulching with dried grass or leaves can prevent winter moisture stress.

Intercultural and weed management: avocado orchards should avoid extensive cultivation to protect surface roots. Intercropping legumes or shallow-rooted crops can smother weeds in young orchards. Gramoxone or glyphosate are good herbicides for heavy rainfall areas. In coffee-based plantations, scruffling coffee plants can control weeds without disturbing avocado tree roots.

Avocado Harvest

Flowering, pollination, and fruiting: Avocado trees start fruiting 5-6 years after planting. Avocados have diurnally synchronized dichogamy. This means that all tree blossoms that open simultaneously will grow into female flowers. When the blossoms reopen as male flowers, the male components will mature. Dichogamy and cross-pollination hinder floral self-pollination. A and B avocado cultivars are categorized by bloom behavior.

Group A opens in the morning and afternoon, whereas Group B opens in the afternoon and morning. The groupings can cross-pollinate. Due to the flower opening process, the avocado fruit set is limited, making insect pollination essential. Hymenopterans, dipterans, and coleopterans pollinate avocado blooms, with hymenoptera being the main pollinators.

Managing Pests and Diseases in High-Density Avocado Plantations

Pests and diseases pose significant challenges in managing high-density avocado plantations. The major diseases affecting avocados include Anthracnose, Phytophthora Root Rot, and Avocado Scab. Anthracnose, caused by Colletotrichumgloeosprotioides, leads to brown circular lesions on fruits, which can result in shedding and deformity. Copper-based fungicides can be used for control.

Phytophthora Root Rot, caused by Phytophthora cinnamoni, affects the roots, causing them to turn black and eventually die. Metalaxyl and potassium phosphonate are recommended treatments. Avocado Scab, caused by Sphacelomaperseae, results in brown or purple spots with a rough texture on the fruit. Tolerant varieties and copper-containing fungicides can help control the scab.

Regarding insect pests, mites, mealy bugs, scales, and thrips are important to manage. Mites like the brown avocado mite and perseamite can damage foliage and affect fruit production. Predatory mites and avoiding chemical pesticides can help control mite populations. Mealybugs, sexually dimorphic insects, can be problematic if insecticides kill their natural enemies.

Ladybird beetles and insecticide sprays can be used for control. Thrips leave scars on the fruit, which can spread and damage the fruit’s quality. Organic mulch and selective insecticides can help reduce thrip populations. Fruit flies, such as Bactrocera dorsalis and B. caryeaea, infest mature fruits and cause rotting. IPM strategies, including sanitation, traps, and bait sprays, can effectively manage fruit fly infestation.

Harvesting and Post-Harvest Tips for High-Density Avocado Plantation

Avocado plants grown from seeds start bearing fruit after five to six years, while grafted plants yield in three to four years. Mature fruits of purple varieties change their color from purple to maroon, while green varieties become greenish-yellow. Harvesting is done when the color of the seed coat within the fruit changes from yellowish-white to dark brown. After harvesting, the mature fruits ripen within six to ten days.

While on the tree, avocados remain hard and only soften after being picked. Each tree can yield approximately 100 to 500 fruits. Harvesting seasons vary across different regions in India, with July to October being the usual harvesting time in Sikkim, June to October in Coorg, and July-August as the peak harvest time in Tamil Nadu.

Avocado do not ripen on the tree, so they must be picked carefully at the right stage of maturity. In India, fruits weighing around 250 to 300 grams are preferred. The most popular varieties include Hass, Fuerte, and Green. Harvested avocados are usually hard and mature and ripen during transportation and distribution. Unripe avocados can be stored for up to four weeks at temperatures between 5.5 to 8°C. Due to small-scale production and scattered production areas, there is no organized marketing system for avocados in India.

Maximizing Yield in High-Density Avocado Plantation

To maximize yield in high-density avocado plantations, planting trees intensively with closer spacing can reduce the number of fruits needed per tree to achieve good yields per hectare.

Tree Spacing: 7 x 7 meters Trees per Hectare: 204 In high-density avocado plantations, the spacing of trees plays a crucial role in determining the fruit yield per tree and hectare. With a tree spacing of 7 x 7 meters and 204 trees per hectare, the number of fruits per tree ranges from 171 to 853, resulting in yields ranging from 8 to 40 tonnes per hectare. Different tree spacings, such as 5 x 3 meters, 3.5 x 3.5 meters, 5 x 2 meters, 2.5 x 2.5 meters, and 1.25 x 1.25 meters, have varying tree densities and corresponding fruit numbers per tree, leading to different yield potentials.
