In Senegal, rice occupies a place of first choice in the daily food. In spite of the importance of this cereal, its production covers only 50 to 80% of the national needs.However, the noted outputs are weak. The total objective of this work is a contribution to food self-sufficiency and aims specifically to the agronomic performance evaluation and the rice adaptation of plate under the conditions of culture of the Southern zone of the Arachidier Basin. Within the framework of this work a device in complete random blocks with 3 repetitions was used and like factor studied the variety. The culture was led under strictly rain hydrous condition. The results of the variance analysis showed a significant variability according to the varieties tested for the unit of the studied characters. They are the earliest varieties Art3-7-l9p8-1-b-b-1 and NERICA 14 which gave the highest outputs between 4615 kg/ha and 4371 kg/ha. The weakest outputs are observed on the level of the late variety (CNAX 3031-78-2-1-7).Under the conditions of the South Arachidier Basin the best varieties associate a good precocity an output in acceptable grain and a good weight of 1000 grains.
