Missed call, IVR, SMS and WhatsApp voice
No app dependency. A farmer can call, use a neighbor's smartphone, or ask an RSK operator to log the case.

Smart water, crop and advisory decisions over a missed call.
A voice-and-SMS platform for small farmers that recommends crop portfolios, detects monsoon dry-spell risk, and routes uncertain crop-health cases to Rythu Seva Kendras with plot evidence attached.
Selected solution
A complete field-to-RSK operating system
Crop portfolio + water-risk engine
Ranks safe, balanced and high-return crops using soil, satellite, rainfall, groundwater and market signals.
Expert queue and district early warning
Low-confidence photo/voice cases go to RSK staff with plot history, then return as voice advice and training labels.
End-to-end web form
One farmer, one plot, one advisory workflow
Fill the form once. The page generates the IVR transcript, crop portfolio, dry-spell alert, SMS fallback, crop-health triage and RSK queue without redirecting anywhere.
