The interaction between plant population and level of nitrogen in transplanted rice was investigated for 2 years during the wet season (June to November) at the mangrove swamps of Warri, Nigeria. Eight individual plant populations and three levels of nitrogen were compared in a replicated split-plot design. There was no significant interactions between spacing and nitrogen level. Rice grain yield increased with increasing N application. The application of 78.4 kg N/ha produced significantly higher grain yield than the control plots. Plants spaced at 20 x 5 cm, 4: 1 regularity (1,000,000 plants/ha) gave the highest yield and were found statistically superior to tho1085se spaced at either 50 x 12.5 cm or 25 x 25 cm (160,000 per ha) and at 20 x 20 cm (250,000 per
