Abstract
Salinity stress affects cultivable areas in coastal districts to varying degrees. Bangladesh's coastal and offshore areas include tidal areas, estuaries, and river floodplains in the south along the Bay of Bengal. Agricultural land use in these areas is very poor, accounting for roughly half of the national average. Bangladesh's main food crop is rice. Rice seed germination, plant height, tiller numbers, and leaf area index are all negatively affected by salinity. Rice (Oryza sativa L.) is the most important cereal crop in terms of cultivated area and total production. It accounts for nearly 20% of the world's dietary energy supply. Salinity is an important abiotic ecological factor that reduces rice and other plant growth and productivity globally. Soil salinity has a global impact on agricultural productivity. Soil salinization is caused by climate change, and the dynamic scarcity of freshwater has harmed crop production worldwide. Proper nutrient management could increase agricultural production throughout saline areas by reducing the negative effects of salinity. This research can be carried out to determine which nutrient element (or elements) benefit rice the most when it is salted.
