Abstract
The present study was undertaken to study the “SCREENING OF RICE GENOTYPES FOR SODICITY TOLERANCE UNDER CALCAREOUS SOIL” during 2019-2020 at the research farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar.The research trial was designed in RBD with 30 plots in each of 3 replication. 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.
