Abstract

Storage without pesticide is a challengeable aspect. The deterioration of physiological quality of seeds during storage was strongly attributed to containers. Storage is the carryover of seed from one season to next sowing. On recommendation of presowing seed management techniques for betterment of plant population, necessitates the storability of treated seeds with expected benefits for longer period of usage. Researchers also expressed that seeds after imposing management techniques could be stored with expected in vigourative effect up to resowing. Traditional rice variety Navara with three different combinations of liquid biofertilizers Azospirillum (15%), Phosphobacteria (15%), Azospirillum (15%) Phospho bacteria (15%), in cloth bag, polythene bag and plastic containers for eight months along with hydro primed and control seeds. The results revealed that after eight months of storage, the seeds primed with Azospirillum (15%) Phospho bacteria (15%) maintained the germination above the seed certification standard with higher seedling quality characters compared to unprimed seed.

Conclusion

The seeds primed with combinations of bio products evaluated for seed quality characters were (15 per cent Azospirillum + 15 per cent Phosphobacteria, 15 per cent Azospirillum, 15 per cent Phosphobacteria) evaluated for storability along with unprimmed and hydroprimed seeds under ambient conditions of coimbatore for 8 months where the primed seeds were dried back to original moisture content and stored in air tight plastic containers under ambient condition. The results revealed that 15 per cent Azospirillum + 15 per cent Phosphobacteria by 15 Azospirillum, 15 per cent Phosphobacteria, performed best compared to unprimed seeds at the end of 8 months of storage, measuring the higher order level of seed vigour characters in terms of germination, seedling length, vigour index and dry matter production.
