Among the oilseed crops, groundnut is one of the most important crops of India. India is the largest producer and exporter of groundnut. Tamil Nadu occupies major area under groundnut crop i.e. 40 per cent of total area. Having a physical target of 337 ha covering 658 beneficiaries, the improved groundnut production technology was demonstrated in 5 sub basins.
