BR23). The experiment comprised three levels of number of seedlings hill<sup>-1</sup> viz. 2, 4, and 6, three nitrogen rates viz. 0, 60 and 120 kg N ha<sup>-1 </sup>and three levels of time of nitrogen application viz. nitrogen application in two equal splits at 15 DAT and early tillering stage (ET); nitrogen application in three equal splits at 15 DAT, ET and panicle initiation (PI) stage; nitrogen application in four equal splits at 15 DAT, ET, PI and flowering (F) stages. The experiment was laid out in a randomized complete block design with three replications. Number of effective tillers hill<sup>‑1</sup>, grain yield and straw yield were the highest when 6 seedlings were transplanted hill<sup>‑1</sup> while all yield contributing characters, grain and straw yields were the highest at 120 kg N ha<sup>-1</sup>. In case of interaction, the highest grain yield was recorded in combination of 6 seedlings hill<sup>-1</sup> × 120 kg N ha<sup>-1</sup> and 120 kg N ha<sup>-1</sup> × three times of nitrogen applications (15 DAT + ET + PI). The highest number of effective tillers hill<sup>-1</sup> and grain yield were recorded in 6 seedlings hill<sup>-1</sup> × 120 kg N ha<sup>-1 </sup>× three times N application (15 DAT + ET + PI) and thus this practice appears as the promising one for late transplant <em>Aman</em> rice ( cv. BR23) cultivation.</p><p>Int J Appl Sci Biotechnol, Vol 3(4): 692-698</p> ER -
