Prices of soybean fell marginally in the benchmark market of Indore due to lack of demand. Demand for soybean has been affected by the low demand for its derivative, soyoil. Soyoil demand falls during summer. Arrivals in Indore were around 1,000, each carrying 100 kg of the oilseed. Futures contracts of soybean on the NCDEX also were trading lower, tracking losses in the benchmark contracts on CBOT. The most active July soybean contract on the NCDEX was down 2.4%.
