Every season, farmers face the same dilemma: buy certified research seeds at a higher cost, or save money with retained local seeds? Field data from across Gujarat makes the answer clear.
The 40% Yield Gap
Field trials across Saurashtra comparing Pragati Super varieties against retained local seeds consistently show a yield advantage of 35–45% in favour of certified seeds. On a 10-bigha field, this is an additional ₹25,000–₹40,000 per season.
Key insight: The extra cost of research seeds (₹800–₹1,200 per bag) is recovered within the first harvest through higher yield and better oil recovery alone.
Why Research Seeds Outperform
1. Genetic Purity
Retained seeds degrade genetically over successive seasons. By the third year, germination rates fall and yields drop. Certified seeds guarantee genetic consistency every season.
2. Disease-Free Material
Local seeds often carry dormant soil-borne pathogens — collar rot, stem rot, and Aspergillus fungi. Research seeds are treated and tested before release.
3. Bred for High Oil Content
Varieties like Super 32 and Super 4 are specifically bred for oil content above 50% — a trait that diminishes within 2–3 seasons of farm retention.
