MUMBAI, May 10 (Reuters) - India silver futures may extend gains for a fourth month in a row on the back of firm cues in the base metals complex, and a pick-up in physical offtake in the domestic markets, analysts said.

India's biggest gold buying festival which is later this month may also spur some buying in silver, which many Indian consumers consider auspicious, traders said.

"The investment appetite is good for silver along with industrial demand," said Pinakin Vyas, assistant vice-president with IndusInd Bank, adding additional buying will happen only if prices fall to 24,000 rupees.

"We are hearing of good demand for Akshaya Tritiya for silver in the market after the slight correction," he said.

India, the world's largest consumer of the precious metal, celebrates Akshaya Tritiya on May 16, when it is considered auspicious to buy precious metals for lasting prosperity. The base metals complex has been displaying firm trend on the back of demand hopes after the news of $1 trillion emergency package to stabilise markets and resolve the Greek debt crisis.

Prices of silver often move in tandem with base metals because of the industrial usage of the white metal.

The most-active July silver contract MSVN0 on the Multi Commodity Exchange rose 5.1 percent in April. It has added about 11 percent in the previous three months, as safe-haven and investment demand supported the white metal.

It was trading 0.78 percent lower on the day at 28,353 rupees per kg at 5:54 p.m.

"There is a bullish trend in silver, buying could be done at 28,100, targeting 28,640/29,250 rupees, maintaining a stop loss of 27,850 rupees," said Arun Kumar Ubbara, an analyst with Way 2 Wealth Securities.

European Union finance ministers agreed on Monday 10 May on emergency measures worth 500 billion euros ($670 billion) to prevent Greece's debt crisis causing turmoil in other euro zone countries, dimming the yellow metal's safe-haven appeal. The yellow metal's rally witnessed last week was mainly on the back of debt concerns in the euro zone.

Prices of the white metal are still down from the all-time high of over 30,000 rupees seen last December.

"There has been some shortage of silver in the market as traders soaked-up the metal during the recent fall," said Prithviraj Kothari, director with Bombay Bullion Association told Reuters in an interview.

"Demand is picking-up, we maintain our bullish view, buying could be done at 28,200, targeting 29,400 rupees," said Aurobinda Prasad, head of research, Karvy Comtrade.
