Agriculture in Chennai District: East Coast Plains and Hills
Tamil Nadu falls mainly in the East Coast Plains and Hills agro-climatic zone (hot humid, 780-1300mm of rain a year across the zone), where deltaic rice bowls (Kaveri, Godavari, Mahanadi) with coconut and chilli is typical. Soils in this zone are mostly alluvial coastal and red loam soil. Crops commonly grown across the zone include Rice (Paddy), Sugarcane, Groundnut, Coconut, chilli, oilseeds.
These are zone-level facts (ICAR / Planning Commission agro-climatic classification), not a crop census of Chennai itself. Chennai's own month-by-month rainfall and temperatures are in the climate section.

Soil, Water & Irrigation
Drip and sprinkler subsidies (45-90%) and a solar pump cut water and power costs. Because soils vary field to field inside a zone, a free soil health card is the only reliable guide to what your own plot needs.
