The Revised September 27 2020 experiment was laid out in a completely randomized design with three Accepted October 19 2020 replications and consisted of two factors. The first factor comprised three salinity concentrations 0 control 2 and 4 and the second factor Keywords had three concentrations of BRs 0 ppm control 2 ppm and 4 ppm. The results showed that under non-saline conditions the control rice Antioxidant enzymes plants sprayed with BRs at a concentration of 2 ppm had the highest values of root length cm leaf area cm2 proportion of Brassinosteroid firm seeds weight of 1000 seeds g and yield Jasmine 85 g barrel . At the salinity level of 4 rice plants sprayed with BRs at Salinity a concentration of 2 ppm demonstrated the highest levels of APX and CAT enzymes. Briefly rice plants grown under higher salinity levels had Corresponding author decreased growth and yield. Spraying BRs helped improve growth and yield parameters of rice under high salinity conditions. Phan Hai Van Email phvan@ Cited as Phan V. H. Bui T. M. amp Nguyen S. D. 2020 .
