সাজনা (MORINGA OLEIFERA)
ORIGIN
সাজনা is native to:
Northern India
The Himalayan foothills
Bangladesh region
Pakistan
Nepal
It later spread throughout Africa, Southeast Asia, and tropical regions globally.
TAXONOMY
Kingdom: Plantae
Order: Brassicales
Family: Moringaceae
Genus: Moringa
Species: Moringa oleifera
EVOLUTION
সাজনা evolved in semi-arid, drought-prone areas, which shaped several features:
Deep root system
Ability to grow with very little water
Leaves rich in nutrients for survival
Rapid growth to outcompete other plants
It has been cultivated for thousands of years for food, medicine, and oil.
DESCRIPTION
Plant Characteristics
Type: Fast-growing, deciduous tree
Height: 6–12 meters
Leaves: Pinnate, small leaflets, rich green
Flowers: Creamy white, fragrant
Fruits: Long, slender pods called “drumsticks”
Seeds: Winged, oil-rich
Leaves and pods are the most consumed parts.
ECOLOGY
সাজনা tolerates:
High temperatures
Low rainfall
Poor, sandy soils
Ecological Importance
Useful in reforestation and soil restoration
Leaves enrich soil when decomposed
Seeds purify water (clarifying and antimicrobial)
Supports biodiversity by attracting bees and insects
CULTIVATION
Propagation
Seeds (very easy)
Stem cuttings for faster growth
Growing Conditions
Sunlight: Full sun
Soil: Light, well-drained
Water: Low to moderate
Temperature: 25–35°C
Harvest:
Leaves: every 30–45 days
Pods: seasonal (winter–spring)
It grows extremely fast—up to 3 meters in the first year.
