This research aims to identify the effects of soil moisture and salinity on aroma quality and yield of Pare Wangi rice. Aroma quality was determined based on 2-Asetyl-1-pirolin (2AP) content. This study was conducted in Pare Wangi, Kori village, East Nusa Tenggara Province. Completely randomized design was used in the study, consisted of two-factor treatment: soil moisture and salinity level. The results showed that Pare Wangi produce higher grain yield (39.55 g/pot) at high soil moisture levels (125% FC). It was decrease to be 32.87 g/pot and 22.36 for soil moisture level 100% FC and 75% FC repectively. At high soil moisture ( 125% FC) and 2.5 g NaCl.kg-1 soil caused an increase of 2AP rice content up to 1.84 ppb. Soil moisture at 75 % FC without NaCl was the best treatment for producing the highest 2AP content (3.19 ppb). 2AP content of rice was positively correlated to rice-aroma score.
