India’s annual infrastructure output growth slowed to a four-month low of 1.4 percent in February, mainly dragged down by a contraction in the production of steel, fertilisers and refinery products, government data showed on Tuesday. The output had expanded 1.8 percent year-on-year in January. The infrastructure sector, which comprises coal, crude oil, oil refining, natural gas, steel, cement, electricity and fertilisers, accounts for 37.9 percent of India’s industrial output.
