Similarly, the spice for delivery in May lost Rs 76, or 1.22 per cent, to Rs 6,150 per quintal in 20,050 lots.
Market analysts said trimming positions by traders, driven by ample stocks position on increased supplies from producing regions in the physical market, mainly weighed on turmeric prices at futures trade.
