At present, the company is selling Muriate of Potash (MoP) at Rs 800 per bag.
"We have reduced the MoP prices by Rs 50. The new rates will be effective from June 1," Indian Potash Ltd (IPL) Managing Director P S Gehlaut said.
The prices are reduced for the MoP used by farmers for agriculture purpose only.
Potash strengthens plant roots and boosts drought resistance. Its prices have come down at less than half its 2009 peak amid a supply glut caused by weak demand and the addition of new production capacity across the globe.
IPL accounts for about 50 per cent of the total country's potash market. The company annually sells more than 15 lakh tonnes.
IPL has also diversified into dairy, cattle feed, sugars and rural warehousing.
