Payload capacities and drone specifications
Agricultural drones are classified by tank payload volume, flight endurance, and rotor configuration.
- 10-Liter Spraying Drones: Hexacopter or quadcopter designs; ideal for smallholder fields, vegetable beds, and hilly terraced crops.
- 16 to 25-Liter Commercial Drones: Heavy-payload multicopters equipped with high-discharge centrifugal atomizers; ideal for large-scale custom hiring across cotton, sugarcane, and paddy.
- Flight Time & Batteries: High-density smart lithium-polymer (LiPo) batteries providing 15 to 20 minutes of flight per charge; fast chargers recharge batteries in 20 to 30 minutes.
- Rotary Atomizers / Centrifugal Nozzles: Produce uniform droplet sizes (100 to 200 microns) driven downward by propeller downdraft to coat both upper and lower leaf surfaces.
- Obstacle Avoidance: Integrated millimeter-wave radar and terrain-following sensors maintain constant altitude over undulating crop canopies.
Agronomic benefits of precision drone spraying
Aerial drone spraying provides major environmental, water, and labor efficiencies.
- Water Conservation: Requires only 8 to 10 liters of water per acre compared to 150 to 200 liters needed for manual knapsack spraying.
- Ultra-Fast Field Coverage: Sprays 1 acre in 7 to 10 minutes, allowing a custom hiring operator to cover 20 to 30 acres daily.
- Zero Chemical Exposure: Operators control the drone remotely from field borders, completely eliminating operator inhalation of toxic pesticides.
- Canopy Penetration: Propeller downwash forces chemical mist deep into dense crop canopies, controlling hidden pests like aphids and plant hoppers.
DGCA regulations, training, and SMAM subsidies
Operating agricultural drones requires compliance with civil aviation rules, supported by central subsidies.
- DGCA Type Certification: Ensure the drone model holds an official Type Certificate from the Directorate General of Civil Aviation (DGCA).
- Remote Pilot Certificate (RPC): Operators must complete certified drone pilot training at a DGCA-approved Remote Pilot Training Organization (RPTO).
- SMAM Drone Subsidies: Subsidies are provided under the Sub-Mission on Agricultural Mechanization (SMAM): 100% grant for ICAR/KVK institutes, 75% for FPOs, and 40% to 50% for individual farmers/women entrepreneurs.
- Namo Drone Didi: Central initiative providing drones and certified pilot training to rural women Self-Help Groups (SHGs).

Common questions
How much water does an agricultural drone need to spray one acre?
An agricultural drone typically uses only 8 to 10 liters of water per acre, achieving significant water savings compared to manual knapsack spraying.
What certification is mandatory before purchasing an agricultural drone in India?
The drone model must possess an official Type Certificate issued by the Directorate General of Civil Aviation (DGCA) to qualify for legal flight and government subsidies.
What subsidy is available for Farmer Producer Organizations (FPOs) buying Kisan Drones?
Under the Sub-Mission on Agricultural Mechanization (SMAM), Farmer Producer Organizations (FPOs) are eligible for up to 75% financial grant for drone procurement.
