Indian soya and sugar futures dropped on Wednesday amid adequate supplies, while gold eased in line with global trends and wheat was steady. September soyabeans at the National Commodity and Derivatives Exchange were down 7.9 rupees at 1,269 rupees per 100 kg.
Refined soyaoil for the same month at the Multi Commodity Exchange (MCX) fell 1.9 rupees to 367.6 rupees per 10 kg.
Traders said physical demand had been sluggish after prices rose 2.5 percent in about seven days, while supplies were good. Soya futures had climbed because of scanty rains in the central state of Madhya Prudish, which produces about two-thirds of India's output.
Traders said rains were needed for the soyabean crop, which was in the flowering stage. Sugar eased with little pick-up in demand, with September sugar 8 rupees lower at 1,842 rupees per 100 kg and October down 6 rupees at 1,850 rupees.
"Prices should rise in a month or so when demand grows in the festival season and stocks will be lower," one trader said. Demand for sugar and edible oils generally increases in the Hindu festival months from September and peaks during Dowel, which is on November 1 this year.
Gold futures followed world markets, with October at the MCX losing 10 rupees to 6,270 rupees per 10 grams and December down 4 rupees at 6,335 rupees.
Gold held steady above $438 an ounce in Asia on Wednesday ahead of United States data, but the yellow metal remained vulnerable to selling due to a firmer dollar.
The local market follows global trends as India, the world's top consumer of the yellow metal, imports most of its gold.
Wheat remained steady, with September futures at NCDEX 1.60 rupees lower at 770.40 rupees.
