Context: TERI scientists have developed nano sulphur that significantly boosts mustard yield by 30–40%, offering a viable solution to India’s chronic low oilseed productivity.
About Nano Sulphur:
- What is Nano Sulphur?
- A nano-formulation of sulphur applied via foliar spray to improve nutrient uptake and crop yield.
- It uses plant-growth promoting bacteria for eco-friendly, enzyme-driven nutrient delivery.
- Developed by: The Energy and Resources Institute (TERI).
- Key Features:
- Enhances yield: Boosts mustard production by 30–40% (up to 3.7 tonnes/ha).
- Increases oil content: Raises oil content by 28–30%.
- Replaces 50% traditional sulphur: Cuts input cost and dependency on bulky sulphur fertilisers.
- Efficient absorption: 90–100% availability through foliar application vs. 10–15% in conventional forms.
- Non-leaching: Prevents nutrient loss in sandy or compact soils.
- Significance:
- Economic gain: Farmers can earn up to ₹12,000/acre in additional revenue.
- Soil health: Addresses sulphur deficiency in 41–45% of Indian soils, especially in major oilseed-producing states (MP, Gujarat, Maharashtra, Andhra Pradesh).
- Sustainability: Completely green formulation with biological agents, unlike chemical-based nano urea or
- Supports self-sufficiency: Offers a sustainable alternative to GM crops like DMH-11 without regulatory hurdles.
