Fertiliser stocks were in focus at the bourses on Thursday, rallying up to 9 per cent on the BSE in intra-day trade, after the Centre increased its share of subsidy for di-ammonia phosphate (DAP) by 140 per cent from Rs 500 to Rs 1,200 per bag. The hike in DAP fertiliser subsidy is due to rising prices of phosphoric acid, ammonia, etc, internationally.
