Two field experiments were carried out in saline soil receiving fertilizers NPK @ 130-75-75 kg ha-1, respectively, to see the effect of seedling age and number of seedling hill-1 on rice growth and yield. Rice seedlings of 25-, 35- and 55-day-old were transplanted in puddled field. Results revealed that seedlings of 25- to 35-day-old produced significantly higher number of tillers and productive tillers hill-1, paddy and straw yields compared with 55-day-old seedlings. In the second experiment, transplanting of two and three seedlings hill-1 of 35-day-old gave more promising results compared with one and four seedlings. Two seedlings hill-1 caused maximum increase in plant height, straw and paddy yield while more number of tillers and productive tillers were recorded with three seedlings hill-1.
