Context
Mustard (largest indigenous edible-oil crop) → Orobanche attack → yield loss → higher edible-oil imports.
Orobanche
• Root-parasitic
• Underground
• Steals nutrients
Impact
• Stunted growth
• Yield ↓ up to 50%
• Rajasthan–Haryana–MP belt affected
Chemical issue
• Glyphosate non-selective → kills crop
• Low-dose ineffective
