Rainfed direct seeded & Semi-dry

* suitable for salt affected soils Note of Caution of the varieties: IR 50 and ADT43 are recommended for Kar, Sornavari and Kuruvai seasons and should not be grown during cold weather period. Improved White Ponni is also susceptible to blast and care should be taken on plant protection measures. All samba/late samba season varieties are likely to get infected with false smut and hence prophylactic spraying has to be adopted.
