Field experiment on “Effect of different age and number of seedlings on growth and yield of machine transplanted rice (Oryza sativa L.)” was conducted at Agricultural Research Station, Gangavathi, University of Agricultural Sciences, Raichur and Karnataka during kharif, 2012 and 2013 in clay soil. Pooled mean of two years indicated that, planting of twenty five days old seedlings recorded significantly higher plant height at harvest (95.41 cm), number of green leaves per plant at 60 DAT (87.52), number of tillers at harvest (734 m-2), leaf area plant-1 at harvest (810 cm2), leaf area index (3.88) and grain and straw yield (5101 and 6335 kg ha-1, respectively), gross and net returns (Rs. 91,141 and 45,178 ha-1, respectively), and benefit cost ratio of 2.01. Similarly among the number of seedlings hill-1, planting of three to four seedling hill-1 recorded significantly higher plant height at harvest (97.34 cm), number of green leaves per plant at 60 DAT (90.41), number of tillers at harvest (787 m-2), leaf area plant-1 at harvest (877 cm2), leaf area index (4.18) and grain and straw yield (5330 and 6585 kg ha-1, respectively), gross and net returns (Rs. 95,190 and 49,165 ha-1, respectively) and benefit cost ratio 2.10.
