The south-east Asian countries are facing a serious threat of arsenic (As) toxicity due to extensive use of As contaminated groundwater for rice cultivation. This experiment was configured to assess the consequences of rice seed priming with selenium (Se) and cultivation in As free and As contaminated soil. The experiment was arranged in a factorial complete randomized design having two factors viz. seed priming and soil As stress with total twenty-five treatment combinations replicated thrice. Seed priming with Se promotes growth, yield under both As free and As stressed conditions. Se supplementation considerably enhanced the tiller numbers, chlorophyll content, plant height, panicle length and test weight of rice by 23.1%, 23.4%, 15.6% and 30.1%, respectively. When cultivated in As spiked soil and compared with control, Se primed plant enhance growth and yield by reducing As translocation from root to aerial parts, expressed as translocation factor (TF). A reduction of TF root to shoot (46.96%), TF root to husk (36.78–38.01%), TF root to grain (39.63%) can be seen among the Se primed plants than unprimed plants both cultivated in similar As stress. Besides these, a noteworthy reduction in estimated daily intake (EDI) and cancer risk (CR) were also noticed with the consumption of cooked rice obtained after cooking of brown rice of Se primed plants than their unprimed counterparts.
