ABSTRACT
A study was conducted on saline tolerant vegetables with their mineral constituents for nutritional security during July 2020 to June 2021. Edible portions of bottle gourd, sweet gourd, sponge gourd, snake gourd and ridge gourd were collected from three selected locations of Borguna and Patuakhali districts. The locations were Sawdagarpara of Borguna district as well as Pakhimara of Khepupara upazilla and Dumki of Patuakhali district. It is noted that the soils of Borguna generally contains high saline in dry season; but during the sampling period the soil at Sawdagarpara observed moderately saline (EC value 6.2 dS m-1) and this might be due to high rainfall during the study year. The vegetable were analyzed for P, K, Ca, Mg and S. In saline area cooperatively lower accumulation of P and higher accumulations of K, Ca, Mg and S were found in most of the vegetable than that of non-saline area. Therefore, the discussed vegetable could be grown in saline area for sufficient mineral compositions. Considering the achieved findings the studied vegetables can tolerate moderate salinity (soil EC value up to 6.2dSm-1) and they can be recommended to grow commercially in the study area for nutritional security. The trend of minerals accumulation in most of the vegetable was Ca>Mg>P>K>S. On the basis of total minerals content the trend of vegetable was found as bottle gourd>ridge gourd>snake gourd>sponge gourd> sweet gourd.
