Besides, restricted supplies from the major producing belts too fuelled the uptrend.
At the Multi Commodity Exchange, cardamom for delivery in August gained Rs 4.70, or 0.49 per cent, to Rs 950 per kg, in a trading volume of 29 lots.
On similar lines, the spice for delivery in September contracts traded higher by Rs 1.80 or 0.19 per cent to Rs 916.50 per kg in 19 lots.
Analysts said fresh positions built up by speculators on the back of rise in demand in the spot market against restricted arrivals from growing regions, mainly influenced cardamom prices at futures trade.
