A field experiment was conducted at Agricultural Research Station, Kampasagar, Nalgonda, during kharif, 2011 withMTU-1010 variety, to find out the optimum nutrient requirement for aerobic rice cultivation. The experiment comprising of two nitrogen levels (120 and 180 kg N ha-1), two phosphorus levels (60 and 90 kg P ha-1), two potassium levels (40 and 60 kg K ha-1) and two iron levels (0 and 25 kg Fe ha-1) were laid in ten plots replicated thrice. The results revealed that application of 180:90:60:25 kg N, P, K and Fe ha-1 registered higher number of tillers and panicles (491 and 381 m-2), filled grains panicle-1 (86.3), 1000-grain weight (26.97 g), grain and straw yields (4960 and 6034 kg ha-1 respectively) than the application of (120:60:40 kg N, P and K ha-1). However, it was on par with (180:90:60 kg N, P and K ha-1) which registered similar number of tillers, panicles (483 and 375 m-2),filled grains panicle-1 (84.7), 1000-grain weight (26.47 g), grain and straw yields (4873 and 5814 kg ha-1 respectively).
