Organic production techniques in Pigeonpea - Seed Treatment

Treat the seeds with a mixture of Beejamrut (200gm/kg seed) and Trichoderma viridi (8 gm/kg of seed). Dry the seeds in shade. Now again treat the seeds with red gram Rhizobium and PSB biofertilizer (5gm each per kg of seed) and dry the treated seeds in shade. Such treated seeds should be sown with 4-6 hour of treatment. In south Indian states, Panchgavya is being used in place of Beejamrut. Seeds are soaked in diluted Panchgavya for 20 min, dried and then treated with Trichoderma viridi, PSBand Rhizobium.
