International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Conclusion
Subsoiling at 2m interval + organic manure (S 3) resulted in higher productivity and profitability
for three years. From fourth year subsoiling had no effect, therefore subsoiling to be
implemented once in three years and addition of organic manure also helps in enhancing the
productivity.
