Seed Treatment With Biofertilizer

• Fungicide-treated seeds, should be again treated with a bacterial culture. There should be an interval of atleast 24 hours between fungicidal and biofertilizer treatments.
• The improved rhizobial strain COC 10 is more effective in increasing the yield. Treat the seeds with 3 packets (600 g/ha) of Rhizobial culture COC 10  and 3 packets (600 g/ha)  of Phosphobacteria developed at TNAU using rice kanji as binder. If the seed treatment is not carried out apply 10packets of Rhizobium (2000 g/ha)  and 10 packets (2000 g)  of Phosphobacteria with 25 kg of FYM and 25 kg of soil before sowing.   Dry the biofertilizer treated seeds in shade for 15 minutes before sowing.

Rainfed : 12.5 kg N + 25 kg P2O5 + 12.5 kg K2O +10 kg S*/ha
Irrigated : 25 kg N + 50 kg P2O5 + 25 kg K2O + 20 kg S*/ha
