This region includes the Coromandel and Northern Circar coasts. Here climate is sub-humid maritime with May and January temperatures rang­ing from 26°C-32°C and 20°C-29°C respectively and annual rainfall of 75 cm-150 cm. The soils are alluvial, loam and clay facing the menacing problem of alkalinity.

The region accounts for 20.33 per cent of rice and 17.05 per cent of groundnut production of the country. Main crops include rice, jute, tobacco, sugarcane, maize, millets, groundnut and oilseeds. Main agricultural strategies include improvement in the cultivation of spices (pepper and cardamom) and development of fisheries.

These involve increasing cropping intensity using water-efficient crops on residual moisture, discouraging growing of rice on marginal lands and bring such lands under alternate crops like oilseeds and pulses; diversifying cropping and avoiding mono-cropping; developing horticul­ture in upland areas; increasing marine, brackish water and inland fisheries; upgrading genetic poten­tial of existing animals; improving tank irrigation by desalting and embanking existing tanks and improv­ing field channels and structures; and providing solutions to the problems of water logging and alka­linity.
