dc.description.abstract Seed priming enhances seed performance in many crop species including rice. But, storing primed seed for longer period of time is the challenge in commercializing of the technology. This study was conducted to investigate the storability of halo-primed and redried seed of upland rice under laboratory conditions. Rice seeds were hydro-primed (distilled water for 24 hours) and halo-primed using different concentrations of calcium chloride in 0.25, 0.5, 0.75% and 1.00% (w/w) CaCl2 solutions for 24 hours and re-dried. The primed seeds were compared with dry seeds. Both primed and dry seeds were stored in low-density polyethylene and high-density polyethylene plastic bags at 25± 3oC for 0, 15, 30, 45, 60, and 75 days. Data on germination percentage, seedling fresh and dry weights, speed of germination, root and shoot lengths, vigor index and thousand seed weight were collected every fifteen days. It was observed that storing rice seed hydroprimed (distilled water) and halo-primed (@1.00% CaCl2), re-dried, and stored in highdensity polyethylene plastic bags could readily maintain seed germination and seedling growth parameters until 45 days whereas low-density polyethylene bags could maintain physiological quality until 30 days. Therefore, it is recommended that rice seed primed with 1.00% CaCl2, re-dried and stored in high-density polyethylene plastic bags could be sold within 45 days after priming en_US
