New Delhi, Sep 15 (IANS): India's food inflation dipped marginally to 9.47 percent for the week ended Sep 3 year-on-year but still hovered high enough to trouble policymakers, according to official data released Thursday.

In the week under review, prices of essential food items were still reigning on the higher side. Onions were 42.98 percent costlier, vegetable prices rose 17.47 percent, while fruits became dearer by 22.64 percent.

The primary articles index, which has a 20.12 percent weight in the wholesale price index, rose by 13.04 percent in the week under review, according to data released by the commerce and industry ministry.

The index for non-food articles rose 18.49 percent for the week ended Aug 20, while the indices for fuel and power increased 13.01 percent.
