| Popis: | The grassland ecosystems in the central Andes of Peru, have extensive vegetation formations dominated by tussock grasslands that are not consumed by Andean livestock (Andean camels, cattle, and sheep), so they are burned by rural inhabitants to cause tender shoots, but that cause serious consequences for the ecosystem and its ecosystem services; however, when used as a supplier of plant fiber, this negative action can be reversed in favor of the care and protection of these vegetation formations. For this to happen, it is necessary to generate knowledge of the recovery potential and productive capacity of these species, for this purpose it has been proposed as a research objective, to evaluate the growth and phytomass production of the shoot after cutting, of 5 species of grasses more widespread, in 5 plots of 900 m2 and 50 subplots of 32 m2, under the effect of the application of cattle manure and phosphate rock, which were controlled for 9 months (October 2020 to June 2021). It has been observed that there are differences between the effect of applied manure, between plant species, and plot location for p ≤ 0.01; likewise, a high canonical correlation between biological variables (canopy cover, canopy height, and dry matter production) and climatic variables (maximum temperature, minimum T. in °C and precipitation in liters/m2) has been evidenced. |
