RESUMO

This research was carried out in 1997, at the Centro de Ciencias Agrarias of the Universidade Federal de Sao Carlos, in Araras, SP, Brazil, to evaluate the behavior of theree growth stages ( S1= initial vegetative stage, s2 = full vegetative stage, and s3= reprodutive stage) of the Crioula alfafa cultivar, in the presence of four water levels (L1=100%, L2=80%, L3= 45-50% and, L4=20-25% of a sprinkler irrigation) in a field trial. Growth stages changed according to water levels, and s2stage was the most affected bywater supply, while s1, was the least one and water showed to be a negative factor to plant establishment.
