Also, reports of higher output estimates this marketing year kept pressure on sugar prices.
At National Commodity and Derivatives Exchange, sugar for delivery in October fell Rs 19, or 0.82 per cent to Rs 2,297 per quintal with an open interest of 31,490 lots.
Similarly, the sweetener for delivery in July contracts traded lower by Rs 18, or 0.80 per cent to Rs 2,225 per quintal in 46,460 lots.
Analysts said, trimming of positions by speculators, driven by adequate stocks position on higher supplies from mills amid reports of higher output, mainly kept pressure on sugar prices at futures trade.
