Kethata Aruna", is the existing fertilizer subsidy programme for paddy sector, which was executed in 2005 in Sri Lanka. Underneath this subsidy programme, the three important fertilizers, i.e. Urea, Triple Tremendous Phosphate (TSP) and Muriate of Potash (MOP), have already been seriously sponsored for paddy farmers While using the intention of promoting the usage of fertilizer to boost nationwide paddy production.
