The study was carried out in the county of Astorga, PR, Brazil, in the Nossa Senhora de Aparecida farm. The objective was to study the sward characteristics and forage accumulation of tanzania grass, deferred and after grazed from 07/23 to 09/18/1999, under different sward height levels. The experimental design was a completely randommized, with two replications. The treatments were four levels of sward height: T1=20, T2=40, T3=60 and T4=80 cm. However, the true sward height levels were used for analysis statistics; T1R1=26,3, T1R2=24,6, T2R1=47,9, T2R2=42,5, T3R1=55,8, T3R2=61,7, T4R1=69,2 e T4R2=71,4 cm. Results indicate that: forage mass and green culm mass increased of the positive linear way with increased of sward height. There was no effect of sward height levels on the forage accumulation.
