Abstract

Dry matter production (DM) and morphological composition were evaluated according to regrowth age (RA; four, six, and eight weeks) and prairie height (PH) in Pennisetum ciliare cv. H-17, during rainy season (RS) and drought (DS). The variables were total MS (TDM), leaf (LDM), stem (SDM), dead material (DMDM) and PH. A completely randomized design with four repetitions and linear regression analysis was used. During RS, the TDM was similar (p > 0.05) between RA (8342 kg ha-1) and decreased 90% in DS. During RS, there was greater (p < 0.05) LDM at four weeks, while at eight there was greater SDM and DMDM. The SDM and DDM were manifested when the PH was 34 cm and 47 cm, respectively. The RA and PH had a significant effect on the performance and structural behavior of DM in Pennisetum ciliare cv. H-17.
