A greenhouse experiment was conducted to evaluate N responses to 12 lowland rice genotypes. Soil used in the experiment was an Inceptisol. The N rates used were Omg kg' (low) and 300 mg kq' (high) of soil. Straw yield, grain yield and panicle density were significantly increased with the addition of N fertilization and genotype treatment. The N X genotype interaction also was significant for these traits, indicating different responses of genotypes with variation in N rates.  aGenotype  aRice  aArroz  aGenótipo  aNitrogênio  aOryza sativa  aSolo ácido1 aSANTOS, A.
