INTRODUCTION
Aloe vera is one of the world’s most commercially valuable medicinal plants, forming the backbone of the global herbal, pharmaceutical, nutraceutical, cosmetic, beverage, and skincare industries. Known scientifically as Aloe barbadensis miller, the plant has gained international significance due to its high gel content, rich bioactive compounds, and multipurpose usage. More than 200 active substances, including vitamins, minerals, enzymes, amino acids, antioxidants, and anti-inflammatory chemicals, make aloe vera a premium crop for wellness industries worldwide.
Global demand for aloe vera has been consistently rising. The herbal sector exceeded USD 250 billion in 2024, and aloe vera’s market share alone is estimated above USD 20 billion. The plant is widely cultivated in India, China, Mexico, the United States, Thailand, Vietnam, Kenya, Egypt, and South Africa. Consumption is high in the United States, Japan, Germany, South Korea, and the Gulf countries.
Aloe vera’s popularity among farmers is due to its low maintenance nature, drought adaptability, year-round harvesting ability, and suitability for organic cultivation. Once planted, aloe continues to produce for 4–5 years, making it a lucrative perennial crop with stable income. This guide provides a comprehensive international standard blueprint for aloe vera cultivation, from soil and climate to planting, management, processing, and export.
BOTANICAL PROFILE AND PLANT SCIENCE
Aloe vera is a perennial succulent belonging to the Liliaceae family. Succulents store water in their fleshy tissues, enabling the crop to survive harsh dry climates. Its leaves grow in a rosette form with thick gel inside and a yellow latex layer under the skin containing aloin.
Scientific Classification:
Kingdom: Plantae
Family: Liliaceae
Genus: Aloe
Species: Aloe barbadensis miller
Morphological Characteristics:
– Height: 50–80 cm
– Leaves: Thick, fleshy, 45–55 cm long
– Leaf texture: Smooth surface with serrated margins
– Growth habit: Rosette-forming, perennial
– Root system: Fibrous and shallow
Active Ingredients:
Acemannan (immunity booster), Aloin (pharmaceutical use), Vitamins A, C, E, B12, Calcium, Magnesium, Zinc, Amino acids, Lignin, and Polysaccharides.
These compounds make aloe vera highly valuable for medicinal, cosmetic, and nutraceutical purposes.
GLOBAL VARIETIES
Worldwide, more than 400 aloe species exist, yet only a few varieties dominate commercial cultivation.
- Aloe barbadensis miller
Most widely grown variety, rich in gel content. Preferred by cosmetic and food industries.
- Aloe perryi
Higher in aloin content; used mostly in pharmaceutical extraction.
- Aloe vera chinensis
Used primarily for beverage production; high purity and smooth gel quality.
Leading Indian Varieties:
– IC111269
– AL-1
– AL-2
– Barbadensis Premium Strain
The choice of variety depends on the targeted industry (cosmetic, medicinal, or beverage).
CLIMATE REQUIREMENTS
Aloe vera thrives in warm climates. It grows in tropical, subtropical, arid, semi-arid, and coastal regions.
Optimal Climate Conditions:
– Temperature: 15–40°C
– Rainfall: 650–1200 mm
– Sunshine: 6–8 hours daily
– Humidity: 40–60%
– Altitude: Up to 2000 m
Frost is extremely damaging and can kill the plant. Therefore, frost-prone regions must use a polyhouse or protective low tunnel in winter.
Excess rainfall or water stagnation promotes fungal growth and reduces leaf gel quality.
SOIL REQUIREMENTS AND FIELD PREPARATION
Aloe vera prefers soil that drains well. Since roots are shallow, heavy clay or waterlogged soils are unsuitable.
Ideal Soil Conditions:
– Soil type: Sandy loam or loam
– pH: 6.0–8.0
– Organic matter: Medium
– EC tolerance: Up to 3 dS/m (fairly salt tolerant)
Land Preparation Steps:
Deep ploughing to break hardpan
Rotavation for fine tilth
Design ridges and furrows for drainage
Add 5 tons FYM and 1 ton vermicompost per acre
Mix neem cake to reduce soil pathogens
Laser leveling to avoid water stagnation
Soil Solarization:
Covering soil with clear plastic for 25–30 days eliminates nematodes, fungal spores, and weed seeds.
PROPAGATION AND PLANTING MATERIAL
Aloe vera is propagated vegetatively using suckers or root divisions.
Quality Sucker Characteristics:
– From 1.5–2-year-old mother plant
– 3–4 large, healthy leaves
– No disease or yellowing
– Strong root development
Plant Population
12,000–14,000 plants per acre
Spacing:
– Row spacing: 1.5 feet
– Plant spacing: 1 foot
Ideal Planting Time:
– Spring: February–March
– Monsoon: July–August
Planting during monsoon improves survival and reduces irrigation requirement.
IRRIGATION MANAGEMENT
Aloe vera tolerates drought but responds well to controlled irrigation.
Irrigation Intervals:
– First month: Water every 7–8 days
– After establishment: Irrigate every 15 days
– Winter: Once every 25–30 days
– Rainy season: No irrigation required
Recommended System:
Drip irrigation
Benefits:
– Saves 40% water
– Prevents fungal attack
– Increases leaf thickness
– Supports fertigation
Avoid flood irrigation because aloe is extremely sensitive to waterlogging.
NUTRIENT MANAGEMENT
Although aloe vera has modest nutritional requirements, balanced nutrition enhances plant growth and gel recovery.
Basal Dose:
– FYM: 5 tons per acre
– Vermicompost: 1 ton
– Neem cake: 100 kg
– Bone meal or phosphate source
Organic Foliar Sprays:
– Panchagavya (15 days interval)
– Jeevamrut
– Seaweed extract
– Vermiwash
Chemical Nutrition (Optional):
A light annual dressing:
– NPK: 50:25:25
– Micronutrients: Zn, Mg, Fe
Organic aloe has higher market demand, especially for export.
WEED, DISEASE & PEST MANAGEMENT
Aloe vera is not highly disease-prone, but management is essential in humid climates.
Major Diseases:
- Root Rot (Fusarium spp.)
Waterlogging is the primary cause.
Solution:
Improve drainage, apply Trichoderma, reduce irrigation.
- Leaf Spot (Alternaria)
Brown patches on leaf surface.
Solution:
Copper fungicides, neem extract, proper spacing.
- Anthracnose
Common in high humidity.
Solution:
Carbendazim rotation, reduce leaf wetness.
Common Pests:
- Mealy Bugs
Appear as cotton-like clusters.
Control: Neem oil, soap solution, predatory insects.
- Aphids
Transmit viral diseases.
Control: Yellow sticky traps, imidacloprid (last option).
- Mites
Cause leaf discoloration.
Control: Wettable sulfur, neem extracts.
GROWTH STAGES
Aloe vera follows a long-term multi-stage growth cycle:
Year 1 — Establishment Phase
