The aim of this study was to evaluate the dynamics of growth and nutritional value of Pennisetum spp (cv. Maralfalfa) at three cutting ages (45, 60 and 75 days) and at two times of the year (high and low rainfall) in the district of Oxapampa, Pasco, Peru. Plant height to flag leaf (AH), number of tillers (NT), green biomass (BV), dry matter (DM), in vitro digestibility of dry matter (DIVMS), crude protein (CP), crude fibre (CF), calcium (Ca) and phosphorus (P) were evaluated in a completely randomized design with a 3x2 factorial arrangement (cut-off age and time of year). The AH did not present significant differences for age at cutting (34.27±4.00, 210.08±4.00 and 251.14±4.00 cm for 45, 60 and 75 days, respectively), nor between seasons (191.91±3.26 and 205.09±3.26 cm in low and high precipitation, respectively). The NT did not show significant differences for age at cutting (54.56...
