ICAR Puttur

Drip Irrigation/Fertigation Calculator

The DCR- Cashew Drip/Fertigation Calculator software has been developed by ICAR-Directorate of Cashew Research, Puttur with funding support of RKVY-RAFTAAR, Government of Karnataka and is designed to aid the growers to find out the water to be supplied through drip irrigation and to calculate the fertilizer to be used while fertigation.
