ABSTRACT
Lowland ecology, which includes irrigated, rainfed, medium deep water and mangrove swamp environments, represents the major rice growing ecology in Nigeria. Varietal development that addresses specific problems has been carried out. The problems are numerous because of the diverse nature of this ecology in terms of water regimes, soil types, and biotic and abiotic conditions. Successes have been recorded in terms of higher yields and resistance to stresses; however, these have failed to contend with emerging problems. The challenges posed include insects, diseases, weeds, nematodes, environmental stresses, government policies, socio-economic factors, human health risks, migration, ageing and HIV/AIDS-related problems.
