Agriculture in Koderma District: Eastern Plateau and Hills
Jharkhand falls mainly in the Eastern Plateau and Hills agro-climatic zone (hot subhumid, 1000-1600mm of rain a year across the zone), where undulating tribal plateau with mostly rain-fed farming is typical. Soils in this zone are mostly red, yellow and lateritic soil. Crops commonly grown across the zone include Rice (Paddy), Ragi (Finger Millet), Maize (Corn), pulses, oilseeds, Niger Seed, Sesame (Til).
These are zone-level facts (ICAR / Planning Commission agro-climatic classification), not a crop census of Koderma itself. Koderma's own month-by-month rainfall and temperatures are in the climate section.

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.
