An experiment was conducted at Instructional Farm, Department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during Kharif season of 2019-2020. The experiment consisted of randomize block design having Factorial arrangement in three replications. In this experiment, 12 treatment combinations including four different age of seedlings D₁- 12 days, D₂- 18 days, D₃- 24 days and D₄- 30 days old seedlings, while three levels of nitrogen viz., N₁- 100% RDN as basal, N₂- 50% RDN as basal + 50% RDN at tillering stage and N₃- 50% RDN as basal + 25% RDN at tillering stage + 25% at panicle initiation, it was found that age of seedlings and nitrogen levels significantly affected plant height, number of leaves per plant, number of grains/panicle, thousand grain weight, grain and Stover yield of rice. Higher plant height of rice was recorded under the treatment combination consisting of transplanting of 12- days old seedling with application of nitrogen in three split doses with the respective values of 50.13, 78.98 and 99.52 cm at growth stage of 30, 60 and 90 DAT, respectively. Similarly, resulted in significantly maximum total number of grains per panicle of rice was recorded under the treatment combination consisting of transplanting of 12- days old seedling with application of nitrogen in three split doses with the respective values of 187.93 . It was concluded from highest grain yield per hectare of rice was recorded under the treatment combination consisting of transplanting of 12- days old seedling with application of nitrogen in three split doses with the respective values of 64.61 q/ha.
