Phenology of five forage species in the swamps of the upper basin of the Ichu and Pampas river

Abstract

The phenological study of forage species in the bofedales of the upper basin of the Ichu and Pampas river, allowed the phenological evaluation of the most dominant and abundant forage species of the Lachocc and Choclocoha bofedales, during the period from December 2017 to October 2018, in closings of 0.75 ha and 1ha respectively. Vegetation coverings were determined through the vegetation censuses, to determine the dominance of the species. The identification of ten plants of the 5 predominant species in both bofedales was carried out, evaluating every 15 days throughout their phenological cycle. The results indicate that Poa gymnantha, Poa perligulata, Calamagrostis rigescens, Calamagrostis vicunarum, Alchemilla diplophyllaand Alchemilla pinnatacomplete their phenological cycle at 226, 212, 218, 218, 170 and 167 days. While the phenology of Distichia muscoidesis directly related to the availability of humidity and the place where it develops. In addition, the phenology of most species coincides with the presence of rainy seasons beginning in December with greater notoriety, lasting until June and July.
