This research was carried out in the SAIS “Túpac Amaru“ (Junín) located at -11.955183 of latitude and -75.707822 of longitude with an average altitude of 4164 m.s.n.m. The objective of the study was to determine the optimal harvest time of seeds of three key native grasses (Festuca dolichophylla, Festuca humilior and Calamagrostis vicunarum). Three crops of seeds were carried out, at 21, 28 and 35 days after full flowering. For each harvest 30 inflorescences marked by species were identified. To determine the optimum harvest time, physical characteristics (purity, weight of 100 seeds and seed size) and physiological (germination and viability) were carried out in the Ecology and Grassland Utilization Laboratory of the Animal Science College - UNALM. For the analysis of the data, a completely randomized design with a 3x3 factorial arrangement was used. The results show that Calamagrostis vicunarum´s seeds exceed in values of purity and viability, 43.6% and 60% respectively, to Festuca humilior´s (37% and 23.3%) and Festuca dolichophylla´s (23.1% and 48.3%), while the latter shows the best results in weight (0.08gr) and seed size (8.4mm). Festuca humilior showed the best germination percentage (33.7%) throughout the evaluation. Regarding the harvest moments, the results show that in the third harvest moment, the highest percentage of purity (38.6%), percentage of germination (28.3%) and viability (49.2%) were found for the three species, therefore the optimum harvest time for the three species evaluated was 35 days after flowering.
