Grow Onion with : Smart Nutrition Tips

Achieve higher Onion yield and uniform bulb quality with precise plant nutrition.

Challenges in Onion (Indian Conditions)
1.Dense planting & close row spacing: Manual spraying often fails to cover lower leaves effectively.
2.High pest & disease pressure:Thrips, purple blotch, downy mildew, and white rot require frequent spraying.
3.Frequent foliar nutrient sprays needed: Micronutrients like zinc, boron, and growth regulators are applied for bulb quality.

Most critical stage in Onion crop : Bulb Initiation to Bulb Development Stage
Most important Nutrient & Micro Nutrients Required for Onion: Potassium, Sulphur & Boron

Why Potassium & Boron is Critical for Onion
1.Increases bulb size & weight
2. Improves bulb colour & shine
3. Enhances pungency (quality)
4. Improves storability & shelf life
5. Reduces water stress effects

How Agricultural Drones Help in Onion Spraying
1.Uniform spray coverage across dense crop canopy
2.Better penetration to lower leaves due to drone downwash
3.No physical contact with plants – safer for labour
4.Saves 60–70% labour cost
5.Reduces water usage by 80–90%
