A field experiment was conducted for two years (December, 2001 to December, 2003) at Imbiakpabai, Bayelsa State-a tidal saline mangrove swamp agro-ecological zone of Nigeria, to compare the agronomic performance of 10 swamp rice hybrids between dry and wet season croppings. Percent germination, days to 50% emergence, plant height (cm), tiller number, number of leaves, grain yield (tha-1) among the rice genotypes all varied significantly (P < 0.05). WITA 4 produced highest grain yield (2.19 tha-1) and lowest grain yield was obtained from Tox 303-13-3-1-1-2 (1.03 tha-1). Between the two cropping seasons, higher grain yield (1.66 tha-1) was obtained in the wet season as compared with 1.34 tha-1 of the dry season. Generally, wet season gave better agronomic performance than dry season. WITA 4 and BW 348-1 have been identified as good cultivars for planting in this agro-ecology, and wet season cropping is preferred to that of dry season. © 2010 EuroJournals Publishing, Inc.
