Aman season, 2002 at experimental field of Khulna University, Khulna to find out the suitable genotype(s) of fine-grained rice (Oryza sativa L.) for the south-west coastal saline region of Bangladesh. Seven fine-grained rice varieties (Kataribhog, Kalizira, Somudraphenna, Chinigudi, Bagunbitchi, Khachra and Parbatzira) were tested. The performance of those varieties was studied under three fertilizer doses (T1=0 kg N/ha + 24 kg P2O5 /ha + 17.64 kg K2O/ha, T2= 40 kg N/ha + 24 kg P2O5 /ha + 17.64 kg K2O/ha and T3 = 0 kg N/ha + 0 kg P2O5 /ha + 0 kg K2O/ha). Yield of Khachra (2.44 t/ha) was highest but statistically similar with Kataribhog (2.15 t/ha), Somudraphenna (2.19 t/ha) and Kalizira (2.11 t/ha). Khachra was also found superior to other varieties in respect of disease and pest resistant. In selected aromatic rice highest yields were obtained when nitrogen, phosphorous and potassium fertilizer were applied. Key words: Aromatic rice, fine-grained, fertilizer management Introduction Rice is grown in more than a hundred countries, with a total harvested area in 2009 of approximately 158 million hectares, producing more
