A study was conducted during July 2020 to June 2021to explore the impacts of salinity on the yield and mineral composition of radish in the challenging as well as salinity prone south-central coastal region of Bangladesh. The study encompassed multiple locations, including PSTU farm, Dumki; south Muradia, Dumki; Nauvanga, Kalapara; Pakhimara, Kalapara of Patuakhali district and Sawdagarpara, Taltoli of Barguna district having EC level 0.87, 0.97, 4.4, 4.8 and 6.4 dSm-1, respectively. The yield of radish was increased with the increasing of soil EC level. Mineral analysis encompassed the examination of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), sodium (Na), zinc (Zn), iron (Fe), copper (Cu) and manganese (Mn) content in Radish. The results unveiled a decreasing trend in P, Ca, S, Zn, Fe, Cu, and Mn levels as soil EC levels rose. In contrast, K, Mg, and Na exhibited an ascending trend with higher soil EC levels. Results indicated that radish displayed a moderate tolerance to salinity, up to a soil EC 6.4 dSm-1. Consequently, it can be recommended for commercial cultivation in the study areas.

Key words: Radish, yield, minerals, salinity, coastal area.
