Castor seed prices turned weak by Rs 22 to Rs 3,937 per quintal in futures trade today after profit- booking by speculators, tracking subdued physical sentiments.
Market players said slackness in industrial demand for soap, pain and lubricant, triggered by increased supplies from growing regions in the spot markets, weighed on market sentiments.
Traders preferred to booking profits at existing levels, which led to the fall in castor seed futures prices, they added.
At the National Commodity and Derivatives Exchange, castor seed delivery for the immediate May contract dropped by Rs 22, or 0.56 per cent, to Rs 3,937 per quintal with an open interest of 42,330 lots.
The delivery of the most-traded June contract declined by Rs 20, or 0.50 per cent, to Rs 3,991 per quintal with the business turnover in 62,790 open lots.
