Contribution of _________towards economic growth has declined considerably in India in the last few decades?

Agriculture

In India, in 1999-2000, nearly 60% were employed in the primary sector (agriculture and mining), 17% in the secondary sector (manufacturing, construction and utilities), and 23% in the tertiary sector (trade, transport, financial services etc.) However, if we look at the contribution of these sectors to economic growth, the share of agriculture has declined sharply, and services contribute approximately half. This is a very serious situation because it means that the sector where the maximum people are employed is not able to generate much income for them. (Government of India, Economic Survey 2001-2002).
