In farm 30 rice genotypes was taken for evaluating valuable parameters such as yield attributes, nutrient uptake, physiological attributes and sodium – potassium ratio at tillering and preflowering stages to identify or select tolerant and susceptible rice genotypes under salt stress condition. Initial soil parameters were measured to know the quality of soil. Based on results, it was noticed that genotypes such as Rajendra Mahsuri, GPV 1, GPV 3 perform better w.r.t physiological attributes and sodium potassium ratio , yield attributes and nutrient uptake while Rajendra bhagwati, prabhat and Rasi perform poor in these aspect of research.EnglishThesis
