Mineral status of sweet gourd in response to salinity at Barguna and Patuakhali districts

摘要: A study was conducted on salinity tolerance of sweet gourd in selected tidal areas of Barguna and Patuakhali district during July, 2013 to June, 2014. Vegetable and soils of different locations were taken under investigation. On the basis of soil salinity, Sonakata, Taltoli, Barguna was selected as saline area (EC value 7.9 dS m-1) and Kadomtola, Dumki; Patuakhali was selected as non-saline area (EC value 1.19 dS m-1). The soil and vegetable were analyzed for Phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), Sulphur (S), Soil pH and EC. In saline area comparatively lower amounts of Phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), Sulphur (S) were found in sweet gourd and sweet gourd leaf than that of non-saline area. Accumulation of different mineral constituents in sweat gourd was remarkably affected by salinity. The uptake of K, S and P in sweet gourd was increased with decrease of soil EC level. The discussed vegetable can grow in saline area with sufficient mineral composition though the amounts of these minerals were found lower than vegetable grown in non-saline area. Considering the findings achieved sweet gourd can tolerate moderate salinity (soil EC value up to7. 9 dSm-1) and might be recommended to grow commercially in the study area for nutritional security.
