Abstract: A Field study was conducted at wetland farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during kharif- Rabi – summer seasons (June/July, December/January, April /May, respectively) in 2014-15 and 2015-16 to study the integrated nutrient management for sustainable growth and production in rice-rice-green gram cropping sequence. The experiment was laid out in split plot design with the three replications. The main plot treatments comprised of incorporation of green manures and residue addition of 30% of paddy straw during both the kharif and rabi season in rice viz., M1- kharif- No application of green manure; rabi- No application of crop residue, M2- kharif- Dhaincha@ 6.25t ha-1; rabi-No. application of crop residue, M3-kharif- No application of crop residue; rabi-Residue addition of 30% paddy straw and M4- kharif- Dhaincha@6.25t/ha; rabi- Residue addition of 30% paddy straw and subplot consists of various fertilizer management approaches- S1-Recommended dose of NPK, S2- STCR approach, S3- LCC based N application. The soil N status, yield and economics were assessed during the course of study. The results revealed that the treatment combination of M4S3 (M4-kharif- Dhaincha@ 6.25t ha-1; rabi- Residue addition of 30% paddy straw; S3- LCC based N application) found to be significantly superior over the other treatments.
