The government on Friday cut its estimate of annual growth for the fiscal year to 4.9 per cent from 5 per cent because of a contraction in the manufacturing and mining sectors.
The revision down will do little to help the Congress party-led ruling alliance, which faces an uphill battle in a general election due by May amid allegations of economic mismanagement, corruption scams and high inflation.
Last week, the Statistics Ministry revised down economic growth for the previous fiscal year to 4.5 per cent - the slowest pace during the decade Manmohan Singh has been prime minister - from an earlier estimate of 5 per cent.
Farm output is expected to grow 4.6 per cent in the fiscal year to March 31, against 1.4 per cent growth a year ago, while the manufacturing sector is seen contracting by 0.2 per cent compared with 1.1 per cent growth in 2012/13, the Statistics Ministry said in a statement.
Finance Minister P Chidambaram expressed satisfaction over the growth projections and exuded confidence that it will improve significantly in the next fiscal year (FY15).
"I am confident that the final estimate will be not less than 5 per cent for the whole year", he said.
Last year, the Finance Minister had projected gross domestic product (GDP) growth of 6.1-6.7 per cent in 2013/14 in his annual budget, but lately lowered the estimates to about 5 per cent.
Chidambaram is widely expected to announce measures, including a cut in excise duties on some products, to push up manufacturing output when he presents an interim budget for the coming fiscal year in Parliament on February 17.
The full-year budget will, however, be presented by the next finance minister after the elections.
Asia's third-largest economy grew at 4.6 per cent annually in the first half of the current fiscal year, down from 5.3 per cent in the corresponding period a year ago.
The services sector, which contributes about 60 percent to gross domestic product, is likely to grow at 6.9 per cent in the current fiscal year, compared with 7 per cent growth a year ago, the data showed.
The construction sector, contributing nearly 8 per cent to GDP, is estimated to grow at 1.7 per cent from 1.1 percent a year ago.
"The data shows that there is an overall slowdown in the economy with construction being very weak together with manufacturing," said Saugata Bhattacharya, chief economist at Axis Bank.
Increases in interest rates by the Reserve Bank of India to rein in near-double digit retail inflation - three times since Raghuram Rajan took charge in September - have also dampened chances of early economic recovery.
"Notwithstanding a favourable monsoon in 2013 and healthy agricultural performance, the pickup in rural demand has been uneven and weaker than expected," said Aditi Nayar, an economist at ICRA, the Indian arm of rating agency Moody's.
The economy grew at more than 9 per cent annually for three straight years during the 2005/06 to 2007/08 period, before being hit by the global financial crisis and high interest rates amid a slower global recovery.
This year, the government has cleared hundreds of much-delayed projects such as power plants, mines and ports, but the impact is expected to be visible only in next year's growth numbers, due to a time lag in actual investments.
Last week, the Reserve Bank of India in its quarterly review said the weakening of private consumption and investment demand had dampened prospects of a second-half pick-up in GDP growth.
Consumption, which contributes about 70 per cent to the near $1.8-trillion ( or nearly Rs 110 lakh crore) economy, is expected to grow 4.4 per cent in fiscal 2013/14, down from 5.2 per cent the previous year, the data showed.
Annual car sales declined by about 5 per cent in the first three quarters, hit by high inflation, fuel prices and interest rates.
