Top oxygen-releasing trees in Indian agroforestry
- Peepal (Ficus religiosa): Features an expansive foliar canopy; performs day-time photosynthesis and nighttime oxygen release via CAM pathways.
- Banyan (Ficus benghalensis): Massive evergreen canopy with prop roots, generating high volumes of oxygen and sequestering substantial atmospheric carbon.
- Neem (Azadirachta indica): Dense foliage releases steady daytime oxygen while acting as a natural air filter and source of organic biopesticides.
- Arjun (Terminalia arjuna): Riverbank and wetland tree known for deep root systems, high oxygen output, and cardiac medicinal bark.
- Jamun (Syzygium cumini): Hardy fruit tree with broad, glossy evergreen leaves producing high biomass and oxygen throughout the year.
Factors influencing oxygen production in trees
- Leaf surface area: Trees with dense, broad leaves and multi-tier canopies capture more sunlight, producing more oxygen per day.
- Maturity and biomass: Healthy, mature perennial trees release significantly more oxygen than young saplings or short-lived shrubs.
- Water and sunlight availability: Adequate soil moisture and unobstructed sunlight maximize photosynthetic stomatal conductance.
Agroforestry benefits on farm borders
Planting oxygenating native trees along field boundaries and village commons creates protective windbreaks, reduces wind erosion, moderates summer heat stress for dairy livestock, and enhances carbon sequestration under voluntary carbon credit programs.

Common questions
Which tree is considered the highest producer of oxygen in India?
Peepal (Ficus religiosa) is widely recognized as one of the highest oxygen-producing trees due to its large leaf surface and nighttime gas exchange capability.
Can trees release oxygen during the night?
While most plants absorb oxygen and release carbon dioxide at night, certain CAM-pathway trees like Peepal can take in carbon dioxide and release oxygen during nighttime hours.
How does boundary tree planting benefit farmlands?
Boundary trees serve as windbreaks that reduce soil moisture evaporation, provide livestock shade, prevent wind erosion, and enrich biodiversity.
