Field-Validated Yield Advantage of Bio Super Phosphate Over TSP – Yala 2025 Ampara

On 9th August 2025, a detailed harvest analysis was conducted in the Dehiattakandiya Agrarian Service Division in Ampara during the Yala season, comparing Sassrika Lanka Bio Super Phosphate (BSP) with conventional imported TSP basal fertilizer.

The evaluation, carried out in collaboration with the Department of Census and Statistics, involved five representative field locations. Each plot maintained comparble conditions, including similar application of other fertilizers and uniform land extent, allowing a reliable comparison of phosphorus sources.

 

Across all locations, BSP consistently outperformed TSP. The average yield recorded under BSP was approximately 7247 kg, compared to 5865 kg with TSP, representing an average increase of around 24 percent.

In some locations, yield improvements exceeded 35 percent, demonstrating the strong field performance of BSP, particularly in soils with lower phosphorus availability.

These results highlight the importance of efficient phosphorus utilization and the role of biologically enhanced fertilizer solutions in improving crop productivity. The findings also reinforce the value of field-based validation in understanding real agricultural outcomes.

Sassrika Lanka continues to work closely with farmers and national institutions to deliver sustainable, locally developed fertilizer solutions that enhance soil health, improve nutrient efficiency, and support long term agricultural productivity in Sri Lanka.
