AB - <p>A field experiment was conducted at Agricultural Research Station, Kampasagar Nalgonda, Telangana during the <em>kharif</em> seasons of 2011 and 2012 to find out the effect of different nursery densities and plant population on grain yield and yield attributes in rice. Tiller number and panicle number m<sup>-2</sup> were significantly higher at 44 hills m<sup>-2 </sup>plant population than 33 hills m<sup>-2 </sup>and 25 hills m<sup>-2</sup>. Panicle length, filled grains panicle<sup>-1</sup> and 1000 grain weight were significantly not influenced with plant population. Though there was non significance difference of grain yield with different plant populations, adopting 44 hills m<sup>-2 </sup>recorded superior grain yield (5.39 t ha<sup>-1</sup>) over 33 (5.08 t ha<sup>-1</sup> ) and 25 hills m<sup>-2</sup> (4.95 t ha<sup>-1</sup>). Among nursery densities, 2.5, 5 and 7.5 kg seed 40 m<sup>-2 </sup>did not show any significant influence on yield attributes and grain yield. Numerically, higher grain yields were observed in 2.5 kg seed 40 m<sup>-2 </sup>(5.3 t ha<sup>-1</sup>) than 5 kg seed 40 m<sup>-2</sup> (5.12 t ha<sup>-1</sup>) and 7.5 kg seed 40 m<sup>-2 </sup>(5.01 t ha<sup>-1</sup>).Nutrient uptake was higher in 44 hills m<sup>-2</sup> than 33 and 25 hills m<sup>-2</sup>. NPK uptake was significantly higher at 2.5 kg seed 40 m<sup>-2</sup> than 7.5 kg seed 40 m<sup>-2</sup>. Higher gross and net returns were earned in 44 hills m<sup>-2</sup> (Rs. 80850 and Rs. 50325) than 25 hills m<sup>-2</sup> (Rs. 74250 and Rs. 48750). 2.5 kg seed 40 m<sup>-2</sup> recorded higher gross and net returns ( ` 79500 and Rs. 52640) than other seed densities.</p>
