Abstract

The experiment was carried out at the Faculty of Ciências Agrárias e Veterinárias, Unesp, Jaboticabal, São Paulo State. The treatments aimed to evaluate five Cynodon cultivars at eleven cutting ages to study the characteristics of growing, and at five cutting ages to evaluate the chemical composition. A random design with split plot was adopted, with three replications, considering cultivars as plot and cutting age as subplots. The following variables were studied: dry matter (DM) production, leaf/stem ratio and the contents of crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF), in green leaf, stem and total plant. The highest DM production was from 14 to 84 days (P<0.01), and did not differ among cultivars. The leaf/stem ratio differ (P<0.01) among cultivars (C) and decreased with plant age (I) showing interaction C x I. The CP contents of the total plant were superior to the stem and inferior to the leaf. The NDF and ADF contents were similar among cultivars. The Cynodon cultivars would be better managed during 28 days of plant growth
