Variation in the irrigation requirement of pigeon pea, kharif maize, rabi maize and groundnut at
Krishna basin under RCP 4.5 and 6.0 (2030s)
Conclusion
The irrigation requirement predicted for pigeon pea, kharif maize, rabi maize and groundnut
are varying substantially at Krishna Basin in coming years’/future scenarios. Due to the
significant spatial variation in irrigation requirements of major crops, irrigation scheduling at
sites in the Krishna basin needs to be site-specific irrigation scheduling. From this study, it
was concluded that in future, the basin requires site specific water policy changes to ensure
the constant sustainability of crops.
